## Insights
- [Thai Industry Codes That Lost the Most Companies, 2015-2025](https://maxdatathailand.com/insights/which-thai-industry-codes-shrank-the-most-by-company-count-2015-2025/): TSIC 60101 lost 1,065 filing companies between 2015 and 2025, the steepest company count decline of any 5-digit Thai industry code with matched data. The count fell from 2,797 to 1,732 over the decade. TSIC 92001 lost fewer filers in raw terms, 754, but fell a sharper 66.37 percent. Thailand's whole filing base still grew 49.05 percent over the same years. Of 938 codes with data in both 2015 and 2025, only 140 shrank at all. This page is the mirror image of the site's fastest-growing industry codes ranking, which covers the same decade from the opposite direction.
- [Thailand's Most and Least Micro-Heavy Industry Sections (2026)](https://maxdatathailand.com/insights/thailands-most-and-least-micro-heavy-industry-sections-2026/): Public administration is Thailand's most micro-heavy industry section, with 86.8 percent of its companies classified as micro by DBD's size bands, as of 17 Jul 2026. The section counts only 38 registered companies. Mining and quarrying follows close behind at 85.3 percent micro. Real estate, agriculture and education all clear 81 percent. Human health and social work sits at the opposite end, just 60.7 percent micro, the lowest share among the 19 sections large enough to trust. The gap between the two extremes runs 26.1 percentage points.
- [Thailand's Median Company Founding Year Is 2019 (2026)](https://maxdatathailand.com/insights/thailands-median-company-founding-year-2026/): The median founding year for a Thai company is 2019, as of 17 July 2026. Of the 1,561,866 companies with a known founding year, exactly half were incorporated in 2019 or earlier. The halfway mark falls at company number 780,933. Companies founded in 2019 or later make up 55.5 percent of that total. The register's typical company is not yet seven years old.
- [Thailand's 14-Year Company Formation Growth Streak, 2007-2025](https://maxdatathailand.com/insights/thailands-14-year-company-formation-growth-streak-2007-2025/): New company formation in Thailand rose every single year from 2008 through 2021, a 14 year unbroken climb. It peaked in 2021 at 151,205 new firms. That is up from just 30,227 in 2007. The streak then snapped: registrations fell 20.69 percent in 2022 and kept falling in 2023, the first back to back decline of the period. Formation has since recovered for two straight years but as of 2025 still sits 14.94 percent below the 2021 peak.
- [Thai Industries That Got More Asset Heavy, 2007 to 2025](https://maxdatathailand.com/insights/thai-industry-sections-capital-intensity-trend-2007-2025/): Education's asset-to-revenue ratio rocketed from 2.5x to 20.8x between 2007 and 2025, the steepest capital intensity climb of any Thai industry section. Financial and insurance climbed too, from 8.0x to 15.8x. That pace still trails education by more than four times over. Professional, scientific and technical services and administrative and support both roughly doubled their ratios over the same 18 years. Four sections became less asset heavy instead. Arts and entertainment led that group, falling from 3.3x to 2.1x.
- [Thailand's Deepest Net-Loss Industry Codes in 2026](https://maxdatathailand.com/insights/thai-industry-codes-with-the-deepest-net-losses-2026/): 353 of Thailand's 1,228 five-digit industry codes report a negative net margin overall, 28.7 percent, as of 17 July 2026. Only 55 of those losses run deeper than negative 50 percent, so most of the red ink is shallow, not catastrophic. The steepest loss among large-revenue codes sits in agriculture, code 03224, at negative 111.4 percent on 230 million baht of revenue. Among the ten deepest-margin large-revenue codes, the biggest dollar loss sits in an information and communication code, where reporting companies lost a combined 6.58 billion baht.
- [Rayong vs Nakhon Ratchasima: Same Companies, 6x the Revenue 2026](https://maxdatathailand.com/insights/same-company-count-different-fortunes-thai-provinces-2026/): No, and Rayong and Nakhon Ratchasima prove it. Nakhon Ratchasima registers 33,958 companies as of 17 July 2026, just 875 more than Rayong's 33,083. Rayong's companies still report 3.20 trillion baht in total revenue against Nakhon Ratchasima's 534.50 billion baht, a gap of about 5.99 times. Rayong ranks fourth nationally for revenue while sitting tenth for company count. Nakhon Ratchasima ranks ninth for company count but only fourteenth for revenue. Headcount and output are two different economies.
- [Same Company Count, 616x Revenue Gap Between Thai TSIC Codes 2026](https://maxdatathailand.com/insights/same-company-count-different-fortunes-thai-industry-codes-2026/): Two Thai TSIC industry codes each carry exactly 1,392 registered companies, yet their total revenue differs by 616 times. TSIC 61101 reported 93.10 billion baht in total revenue as of 17 July 2026. TSIC 63120, with the identical company count, reported just 151.03 million baht. Only 40.7 percent of companies under 61101 are still active, against 5.7 percent under 63120. Company count alone tells you almost nothing about a sector's economic weight.
- [18 Industry Codes Generate Half of Thai Corporate Profit 2026](https://maxdatathailand.com/insights/profit-concentration-among-5-digit-thai-industry-codes-2026/): Eighteen. That is how many of Thailand's 1,207 five digit industry codes it takes to generate half of the country's net corporate profit, as of 17 July 2026. Those 18 codes report 50.79 percent of the 3.29 trillion baht in total net profit, while holding just 5.96 percent of companies registered under a profit reporting code. One code alone, sitting in the financial and insurance section, earns 10.35 percent of all profit by itself. The winning codes span nine different industry sections, not one dominant trade, a wider spread than the revenue and asset concentration already published on this site.
- [Do Large-Company Heavy Thai Industries Survive Longer 2026](https://maxdatathailand.com/insights/do-thai-industries-with-more-large-companies-survive-longer-2026/): The correlation is 0.05, essentially zero, between how large-company heavy a Thai industry code is and how well its companies survive, as of 17 July 2026. The analysis covers 745 Thai industry codes with at least 100 registered companies each. Split those codes into four quartiles by large-company share and the weighted survival rate rises from 44.70 percent in the lowest quartile to 53.85 percent in the highest. That gap is 9.15 points. Among the 20 codes most packed with large companies, survival still swings from 24.66 percent to 80.10 percent. A heavy large-company mix does not reliably buy durability.
- [Thailand's Biggest Industry Code Revenue Collapse: TSIC 61209 (2026)](https://maxdatathailand.com/insights/which-thai-industry-codes-lost-the-most-revenue-2015-2025/): TSIC code 61209 lost 98.4 percent of its revenue between 2015 and 2025, the steepest drop of any Thai industry code with a meaningful base. Revenue fell from 65.31 billion baht to 1.01 billion baht in a decade. Three more codes lost more than 95 percent of their revenue over the same years. Section J, the code's parent industry, still grew 11.8 percent overall. Strip this one code out and the rest of section J grew 20.9 percent instead. A handful of shrinking codes can drag down an entire sector's growth rate even while the whole economy keeps expanding.
- [Which Thai Industries Keep the Most Companies Active in 2026](https://maxdatathailand.com/insights/which-thai-industries-keep-the-most-companies-active-2026/): Human health and social work keeps 73.89 percent of its registered companies active today, the highest current status share of any industry section as of 17 July 2026. Real estate and water and waste follow at roughly 62 percent each. Households as employers sits at the very bottom with only 9.38 percent active, though that section holds just 32 companies in total. Among sections with real scale, mining and quarrying is the weakest, with only 30.86 percent of its 8,231 companies still active. Nationally, exactly half of the 1,986,709 classified companies carry an active status.
- [Thailand's 10 Border SEZ Provinces Compared, 2026](https://maxdatathailand.com/insights/thailands-special-economic-zone-provinces-2026/): Songkhla anchors Thailand's ten Special Economic Zone border provinces with 28,543 registered companies, as of 17 July 2026. Trat has just 3,331, the smallest of the group. That is an 8.57 times gap between provinces holding the same SEZ status. Together the ten provinces hold 89,654 companies, only 4.51 percent of Thailand's 1,989,709 registered firms. Their combined revenue of 1.53 trillion baht is a thinner 1.91 percent of the national total, proof that a shared policy label did not produce shared results.
- [Thailand's Rarest Company Types: Households and Extraterritorial 2026](https://maxdatathailand.com/insights/thailands-rarest-registered-company-types-2026/): Thirty two companies in Thailand are classified as households employing domestic staff, and only 4 as extraterritorial organizations, the two smallest of the registry's 21 industry sections as of 17 July 2026. Together they make up just 0.0018 percent of the 1,989,709 companies on the books. Households run an unusually strong 13.67 percent net margin. Extraterritorial organizations post a net loss equal to 10.0 percent of revenue. The next smallest section, public administration, still counts only 38 companies before the numbers jump into the thousands.
- [Thailand's Equity Growth vs Revenue Growth, 2007 to 2025](https://maxdatathailand.com/insights/thailands-equity-growth-vs-revenue-growth-2007-2025/): 4.53. That is how many times total reported equity in Thailand's company register multiplied between 2007 and 2025, rising from 8.48 trillion baht to 38.41 trillion baht. Revenue grew far more slowly over the same 18 statement years, up 2.83 times, from 23.99 trillion baht to 67.95 trillion baht. Equity now equals 56.5 percent of yearly revenue across the registry, up from 35.3 percent in 2007. Thai companies are building up their capital base faster than they are growing sales, a pattern distinct from simple business expansion.
- [Thailand's Falling Asset Turnover Ratio, 2007 to 2025](https://maxdatathailand.com/insights/thailands-asset-turnover-ratio-trend-2007-2025/): Thailand's corporate asset turnover ratio has fallen over eighteen years, despite several rebound years along the way. Companies generated 83.3 baht of revenue per 100 baht of assets in 2007. That figure sank to 65.4 baht by 2025. The gap amounts to a 17.9 percentage point decline. Total corporate assets grew about 3.6 times over the period. Revenue grew far more slowly, roughly 2.8 times. The ratio hit its lowest point in 2020, at 52.8. Thai firms are simply carrying more balance sheet weight for every baht of sales than they did two decades ago.
- [120 Thai Industry Codes Where Every Firm Is Micro (2026)](https://maxdatathailand.com/insights/thailands-all-micro-industry-codes-2026/): 120 of Thailand's 1,228 five digit TSIC industry codes have never produced a single small, medium or large company, as of 17 July 2026. That is 9.8 percent of every industry code in the registry. Together those 120 codes hold just 506 companies, 0.03 percent of the 1,986,709 Thai firms with a recorded size band. The biggest of them, TSIC 92009 in the arts and entertainment section, counts only 54 companies and one still active. Codes stuck at all micro also survive worse, 24.5 percent active against 50.0 percent nationally.
- [Thai Industry Codes Where One Firm Owns Nearly All Revenue 2026](https://maxdatathailand.com/insights/thai-industry-codes-where-one-firm-takes-nearly-all-the-revenue-2026/): TSIC code 10411 carries 28 registered companies, and one of them, T S Oil Industry Company Limited, reports 99.99 percent of the code's total revenue, as of 17 July 2026. Only 3 of those 28 companies filed a financial statement, and just 4 remain active. This is not a one-off. Among 225 Thai industry codes carrying 20 to 99 registered companies each, 7 show one firm holding at least 95 percent of the code's revenue, and 2 clear 99 percent outright. A registry that lists two dozen names in a code can still be a market of one.
- [Thai Industries With the Thinnest Equity Cushion in 2026](https://maxdatathailand.com/insights/thai-industries-with-the-thinnest-equity-cushion-2026/): Education companies fund just 5.87 percent of their assets with equity, the thinnest solvency cushion of any Thai industry section as of 17 July 2026. Arts and entertainment follows at 19.9 percent, then financial and insurance at 26.83 percent. Extraterritorial organizations post the thickest cushion of any section at 87.82 percent, though that group holds only 3 reporting companies. Among sections with real scale, mining and quarrying carries the thickest buffer at 65.95 percent. The gap between education and mining runs to 60.08 percentage points.
- [Construction vs Manufacturing in Thailand: Assets and ROE 2026](https://maxdatathailand.com/insights/construction-vs-manufacturing-companies-in-thailand-2026/): Manufacturing firms in Thailand carry average total assets of 163.7 million baht per company, versus just 23.2 million baht for construction firms, a gap of 7.07 times. Manufacturing's return on equity runs at 9.84 percent. Construction earns only 2.55 percent, so manufacturing's return is 3.85 times construction's. Construction still outnumbers manufacturing by company count, 283,534 registered firms against 230,396, as of 17 July 2026.
- [Just 12 Thai Industry Codes Hold Half of Corporate Assets 2026](https://maxdatathailand.com/insights/which-thai-industry-codes-hold-half-of-corporate-assets-2026/): Twelve. That is how many of Thailand's 997 five digit industry codes with asset data it takes to reach half of the country's corporate balance sheet. Those 12 codes are 1.2 percent of all coded industries. They hold 51.1 percent of the country's 102.6 trillion baht in reported assets as of 7 July 2026. One code alone holds 22.2 percent of the national total. Just 19 companies file under it. The other 985 codes split the remaining 48.9 percent among thousands of businesses.
- [Two Ways to Average Thai Company Revenue in 2026](https://maxdatathailand.com/insights/two-ways-to-average-thai-company-revenue-2026/): Average revenue per Thai company is either 40.3 million baht or 63.4 million baht, and the difference comes entirely from the denominator. Divide Thailand's 80.15 trillion baht in reported revenue by all 1,989,709 registered companies and the average is 40.3 million baht. Divide the same 80.15 trillion baht by the 1,263,354 companies that actually filed financial data and the average jumps to 63.4 million baht. That is a 57.5 percent gap between two numbers describing the same economy. Neither figure is wrong. They simply answer different questions about who counts as a company.
- [Thailand's Top 5-Digit TSIC Codes by Company Count 2026](https://maxdatathailand.com/insights/top-5-digit-tsic-codes-by-company-count-thailand-2026/): 165,550 companies in Thailand carry TSIC code 41002, an unnamed construction code, making it the single largest 5-digit industry code in the country as of 7 July 2026. That is 8.32 percent of every registered company in Thailand. The next largest code, 68102 in real estate, holds 59,095 companies, less than half as many. Two of the top five codes belong to the construction section. Together the top five codes hold 351,016 companies, 17.64 percent of the national total, and the registry cannot spell out what any of them actually do.
- [Thailand's Top 10 Provinces by Registered Company Count 2026](https://maxdatathailand.com/insights/top-10-thai-provinces-by-company-count-2026/): Bangkok leads Thailand with 812,799 registered companies as of 7 July 2026. That is 6.40 times second place Chon Buri's 127,023, a gap of 685,776 companies. Nonthaburi ranks third at 102,370, then Samut Prakan and Pathum Thani, three provinces that ring the capital. Chiang Mai is the top province outside Greater Bangkok and the eastern seaboard at 65,164. Together the top 10 provinces hold 72.67 percent of every registered company in the country, leaving 67 provinces to split the rest.
- [Thailand's Industry Register Share Shift, 2007 to 2025](https://maxdatathailand.com/insights/thailands-industry-register-share-shift-2007-2025/): Manufacturing's share of Thailand's filing companies fell from 16.6 percent in 2007 to 11.6 percent in 2025. Professional, scientific and technical services rose from 6.4 percent to 8.5 percent over the same eighteen years. Wholesale and retail trade and construction also lost ground, while the classified filing base itself grew from 314,504 companies to 712,785, up 126.6 percent. Thailand's economy of filers shifted measurably from industry and trade toward services and expertise.
- [Thailand's Most Capital-Intensive 5-Digit Industry Codes (2026)](https://maxdatathailand.com/insights/most-capital-intensive-5-digit-industry-codes-in-thailand-2026/): TSIC code 64191 holds 22.75 trillion baht in total assets as of 7 July 2026. Just 19 filing companies sit inside that code. That works out to roughly 1.2 trillion baht in assets per firm, the highest of any five digit industry code in Thailand. The code sits inside the financial and insurance section, and its largest filer is Bangkok Bank Public Company Limited. It beats the second ranked code by more than 30 times. Those 19 companies alone hold 22.2 percent of every baht of assets reported by Thai companies with a filed statement that year.
- [Financial Sector Nets 25.4% Margin, IT Just 5.8%, 2026](https://maxdatathailand.com/insights/information-communication-vs-financial-insurance-in-thailand-2026/): Financial and insurance companies average 133.1 million baht in revenue per firm and keep 25.4 percent of it as net profit, a margin more than four times the 5.8 percent that information and communication firms manage. Finance counts 35,567 companies on the register against 52,537 for information and communication. Yet the average finance company banks over 16 times more net profit each year. Return on assets flips the story though, 1.80 percent for finance against 2.36 percent for information and communication, because bank balance sheets carry far more capital per firm.
- [How Few Industries Hold Half of Thai Profit, 2026](https://maxdatathailand.com/insights/how-few-industries-hold-half-of-thai-profit-2026/): Two of Thailand's 21 industry sections generate more than half the country's net profit, as of 7 July 2026. Manufacturing alone contributes 1.10 trillion baht, 33.4 percent of the national total. Financial and insurance adds 0.84 trillion baht, 25.5 percent more. Together the two sections reach 1.94 trillion baht, 58.9 percent of the national total. Wholesale and retail trade holds the most companies of any section, 715,976 of them, yet contributes only 15.0 percent of profit. Profit concentrates far faster than the company count does.
- [Fastest-Growing Thai Industry Codes by Company Count, 2015-2025](https://maxdatathailand.com/insights/fastest-growing-thai-industry-codes-by-company-count-2015-2025/): TSIC 47912, an unnamed wholesale and retail trade code, grew 916 percent in filing companies between 2015 and 2025. The count rose from 641 to 6,513 over the decade. That is the fastest growth rate of any 5-digit Thai industry code with a meaningful starting base. Thailand's entire filing company base grew only 48.9 percent over the same decade. This code expanded more than eighteen times as fast as the average. Four of the ten fastest-growing codes sit inside wholesale and retail trade. The story here is entity count, not revenue, a different lens from the site's revenue growth ranking.
- [Large-Company Mix and Net Margins in Thai Industry Codes 2026](https://maxdatathailand.com/insights/do-thai-industries-with-more-large-companies-earn-higher-margins-2026/): Thai industry codes where large companies make up 20 to 40 percent of the company count post an average net margin of 12.67 percent. Codes where large firms are under 20 percent of the roster average just 2.30 percent, a gap of 10.36 percentage points. Only seven of 967 sizable TSIC codes fall in that higher band, covering 862 companies. The single code where large firms exceed 40 percent of the roster settles back to 9.34 percent, so the pattern is not a straight line upward.
- [Mining Firms File Financial Statements Least Often 2026](https://maxdatathailand.com/insights/which-thai-industries-file-financial-statements-least-2026/): Mining companies file a financial statement only 43.4 percent of the time, the lowest rate among Thailand's 18 major industry sections, as of 7 July 2026. Electricity and gas leads at 79.2 percent. The gap between the two is 35.8 percentage points, despite both being capital heavy sectors. The national filing rate across all classified companies sits at 63.5 percent. Five sections, including mining, construction and wholesale trade, file below that national average.
- [The 428,000-Company Gap in Thailand's Founding Year Data (2026)](https://maxdatathailand.com/insights/the-missing-founding-years-in-thailands-company-register-2026/): Summing every dated new company record from 2007 through 2025 in Thailand's company register yields 1,561,866 firms. The full register holds 1,989,709 registered companies as of 7 July 2026. That leaves a gap of 427,843 companies, 21.5 percent of the register, with no founding year captured anywhere in the yearly series. The founding year table and the separate statement year table both start precisely at 2007. That shared cutoff points to a digitization boundary in the underlying registry data, not a sudden wave of centuries old firms.
- [Thailand's ROE Minus ROA Gap: 2007 to 2025](https://maxdatathailand.com/insights/thailands-roe-roa-leverage-gap-2007-2025/): Borrowed money widened the gap between Thailand's return on equity and return on assets to 8.99 percentage points in 2013, the widest reading in nineteen years, as of 7 July 2026. That gap narrowed to just 2.81 points in 2019, the tightest reading in the series. By 2025 it sat at 4.81 points, roughly half the 2013 peak. The average gap across all nineteen years runs 6.32 points. The swing traces how much debt amplified shareholder returns each year since 2007, a pattern the debt load and assets to equity figures on this site do not show on their own.
- [Thailand's Most Volatile Industry Codes by Revenue 2026](https://maxdatathailand.com/insights/thailands-most-volatile-industry-codes-by-revenue-2026/): TSIC code 47524, in wholesale and retail trade, is Thailand's most volatile industry code by revenue, moving 67.9 times from its lowest year to its highest. Its revenue jumped 37 times over in a single year, from 330 billion baht to 12.33 trillion baht, then fell 97.5 percent the very next year. Company counts barely moved across that swing, ruling out a wave of new filers as the driver. Across the 368 codes with enough history and scale to compare fairly, the typical code carries a volatility score of just 0.33, nine times calmer than the leader.
- [Thailand Transportation vs Administrative Support Revenue 2026](https://maxdatathailand.com/insights/thailands-logistics-sector-vs-administrative-support-2026/): Thailand's transportation and storage companies average 42.91 million baht in yearly revenue per firm, 2.57 times the 16.69 million baht that administrative and support companies average. Return on equity tells a sharper story. Transportation earns 11.02 percent against administrative and support's 4.85 percent, more than double. Administrative and support fields more companies, 100,691 against transportation's 85,273, yet it converts barely half of transportation's total revenue into national output.
- [Digital Economy vs Professional Services in Thailand 2026](https://maxdatathailand.com/insights/thailands-digital-economy-vs-professional-services-2026/): Professional and technical services post a 13.6 percent net margin as of 7 July 2026, more than double the 5.8 percent margin in information and communication. Flip the lens to scale and the ranking reverses. Information and communication generates about 25.4 million baht in revenue per company, roughly 3.25 times the 7.8 million baht that professional services earns per company. Professional services also runs on nearly triple the headcount of firms, 138,962 against 52,537. Bigger companies, thinner margins. Smaller companies, fatter ones.
- [Thailand Company Register Freshness: 128,617 New Firms in 2025](https://maxdatathailand.com/insights/thailands-company-register-freshness-2026/): 128,617 companies joined Thailand's business register in 2025, the most recent full year of data. That is 6.46 percent of the entire national register. Roughly one company in every fifteen on file was born that single year. 2024 added a smaller 121,657 companies. Over the past decade, 1,134,729 companies joined the register. That decade alone accounts for 57.03 percent of everything on file today.
- [40 Thai Industry Codes With Zero Large Companies in 2026](https://maxdatathailand.com/insights/thai-industries-with-no-large-companies-2026/): Forty Thai industry codes with at least 500 registered companies apiece have never produced a single large company, together holding 51,740 firms. That is 9.7 percent of the 413 industry codes large enough to expect a giant. Wholesale and retail trade and accommodation and food service contribute five such codes each, more than any other sector. Micro enterprises make up 81.8 percent of these firms, well above the national average of 75.1 percent.
- [How Few Industry Codes Generate Half of Thai Revenue 2026](https://maxdatathailand.com/insights/how-few-industry-codes-generate-half-of-thai-revenue-2026/): Thirty industry codes generate half of Thailand's corporate revenue. That is 2.44 percent of the country's 1,228 five digit TSIC codes, as of 7 July 2026. The top 30 codes together report 40.32 trillion baht, 50.35 percent of the 80.08 trillion baht attributed to all classified codes. One single code, inside the wholesale and retail trade section, accounts for 12.79 percent of that revenue by itself. Those same 30 codes hold only 18.83 percent of the companies carrying a code, so revenue concentrates far faster than headcount does.
- [Five Boom Years Built 41% of Thailand's Company Register in 2026](https://maxdatathailand.com/insights/how-few-boom-years-built-thailands-company-register-2026/): Forty one point two percent of every Thai company with a known founding year was registered in just five calendar years, all of them since 2019. Thailand's registry holds 1,561,866 companies with a dated founding year across 19 years, from 2007 to 2025. The five busiest years, 2021, 2025, 2020, 2024 and 2022, added 643,829 new companies between them. The other fourteen years produced the remaining 58.8 percent. Registration did not climb steadily, it surged.
- [Widest and Narrowest Net Margins Among Thai Industry Codes 2026](https://maxdatathailand.com/insights/which-thai-industry-codes-have-the-widest-profit-margins-2026/): The widest net margin among Thailand's roughly 1,228 five digit industry codes is 87.05 percent, held by a single code, as of 7 July 2026. Among codes classified as financial and insurance specifically, one code leads at 73.19 percent. The worst performer in the whole registry is a different code at negative 93.50 percent. Three information and communication codes also post margins below negative 32 percent. None of this shows up at the 21 section level, where these same codes blend into averages of a few percentage points either side of zero.
- [Thai Industry Codes With the Most Large Companies, 2026](https://maxdatathailand.com/insights/which-thai-industry-codes-are-heaviest-with-large-companies-2026/): Thailand's most large-company-heavy five-digit industry code is 10722, a sugar-manufacturing code where 30.18 percent of registered firms are large. That is against a national rate of just 0.7 percent. The vegetable and animal oil code 10420 runs close behind at 22.52 percent large. Meanwhile 490 of Thailand's industry codes count zero large companies at all. Rice growing, cattle raising and vegetable growing each carry hundreds of registered firms and not one large company between them.
- [Tourism vs Arts and Entertainment: Net Margin in Thailand 2026](https://maxdatathailand.com/insights/tourism-vs-arts-and-entertainment-companies-in-thailand-2026/): Tourism and hospitality, coded as accommodation and food service in DBD data, posts an aggregate net margin of 5.66 percent as of 7 Jul 2026. Arts, entertainment and recreation, its neighbor in Thailand's leisure economy, runs a net loss of negative 1.09 percent. That is a 6.75 point gap between two sectors built on the same tourists and free time. Tourism and hospitality has 83,598 registered companies, 4.52 times the 18,486 in arts and entertainment. Arts and entertainment is one of only two of Thailand's 21 industry sections in the red, and the only one of meaningful size.
- [Thailand's Narrowest and Broadest Industry Codes 2026](https://maxdatathailand.com/insights/thailands-narrowest-and-broadest-industry-codes-2026/): 257 of Thailand's 1,228 five digit industry codes count fewer than 20 registered companies each, as of 7 July 2026. That is one code in five reduced to a micro niche. One hundred fifty seven codes hold five companies or fewer, and forty seven hold exactly one. At the other end, 296 codes cross the 1,000 company mark. Just 47 codes, 3.83 percent of the total, already hold 1,018,528 companies, 51.27 percent of the whole registry. The single busiest code alone carries 165,550 companies. Thailand's industry map is a long tail of tiny slots under a handful of giants.
- [Thailand's Corporate Assets-to-Equity Ratio: 2007 to 2025](https://maxdatathailand.com/insights/thailands-corporate-assets-to-equity-ratio-2007-2025/): 3.40. That is where Thailand's aggregate corporate assets-to-equity ratio, total assets divided by total equity, stood in 2007. By 2025 it had fallen to 2.68. Total assets across filing companies grew 3.57 times over those 18 years. Total equity grew faster still, 4.53 times. The ratio dipped to 2.44 in 2018, a year when a wave of newly filed statements briefly distorted the count. Outside that anomaly, the broader decline is real. Thai companies now fund more of their balance sheet with equity than they did in 2007.
- [Thailand's Corporate Debt Load: 2007 to 2025](https://maxdatathailand.com/insights/thai-corporate-debt-load-2007-2025/): Thailand's registered companies carried 64.43 trillion baht in combined liabilities in statement year 2025, as of 7 July 2026. That is up from 20.32 trillion baht in 2007, a rise of 217.1 percent in eighteen years. Total debt roughly tripled, 3.17 times the 2007 level. Shareholder equity grew even faster over the same span, up 353.1 percent, so the debt to equity ratio actually fell, from 2.40 in 2007 to 1.68 in 2025. Thai companies are borrowing far more money in absolute terms while relying less on debt to fund the balance sheet than they did eighteen years ago.
- [Thailand's Top 5 Provinces Hold 80% of Company Revenue, 2026](https://maxdatathailand.com/insights/revenue-concentration-by-thai-province-2026/): Thailand's top five provinces by revenue, Bangkok, Samut Prakan, Chon Buri, Rayong and Pathum Thani, generate 80.5 percent of the country's 80.15 trillion baht in reported company revenue as of 7 Jul 2026. Ranked instead by company count, a different top five holds only 61.4 percent of registered companies. Bangkok alone produces 63.1 percent of national revenue. Rayong ranks tenth by company count but fourth by revenue, driven by heavy industry. Money concentrates in Thailand's provinces far more tightly than company headcount does.
- [How One 5-Digit Code Dominates Thai Industry Sections, 2026](https://maxdatathailand.com/insights/how-much-of-each-thai-sector-sits-in-one-industry-code-2026/): Electricity and gas is 89.12 percent a single five digit industry code in Thailand, more than any other sector. Accommodation and food service is 61.24 percent one code, mostly restaurants. Construction runs 58.38 percent through one code too. Manufacturing sits at the other extreme, its 230,396 companies spread so thin that the largest single code holds just 4.94 percent, as of 7 Jul 2026.
- [Thailand's Fastest Growing Industry Code: TSIC 63113 (2026)](https://maxdatathailand.com/insights/fastest-growing-thai-industry-codes-by-revenue-2015-2025/): TSIC code 63113 grew revenue 32.4 fold between 2015 and 2025, the fastest of Thailand's five digit industry codes with a meaningful starting base. Revenue rose from 3.58 billion baht to 115.97 billion baht in a decade. The code sits inside the information and communication section, which grew only 11.8 percent over the same ten years. Strip this one code out and the rest of the section actually shrank 1.4 percent. A single sliver of the economy produced more revenue growth than its entire parent sector managed on its own.
- [Thailand Agriculture vs Manufacturing: Size and Margin 2026](https://maxdatathailand.com/insights/agriculture-vs-manufacturing-companies-in-thailand-2026/): The average Thai manufacturing company reports 175.0 million baht in yearly revenue, more than four times agriculture's 42.0 million baht, as of 7 July 2026. Manufacturing also earns a fatter margin, 4.37 percent against agriculture's 2.55 percent. Its return on equity of 9.82 percent triples agriculture's 2.73 percent. Yet agriculture's revenue grew 96.5 percent over the past decade, nearly four times manufacturing's 24.6 percent gain. Bigger and more profitable does not mean faster growing.
- [Which Thai Industries Turn Assets Into Revenue Fastest 2026](https://maxdatathailand.com/insights/which-thai-industries-turn-assets-into-revenue-fastest-2026/): Wholesale and retail trade generates an estimated 0.96 baht of revenue for every baht of assets on the books, the fastest of any major Thai industry section, as of 7 July 2026. Financial and insurance sits at just 0.05 baht per baht of assets. That is a gap of roughly 19 times between Thailand's two largest sectors by total assets. Manufacturing is the only other section above the halfway mark. It turns over 0.67 baht per baht of assets. Education is the single slowest section at 0.04.
- [Thailand's Biggest Net Margin Swings by Industry, 2015-2025](https://maxdatathailand.com/insights/which-thai-industries-improved-net-margin-most-2015-2025/): Mining and quarrying widened its net margin more than any other Thai industry section between 2015 and 2025. The section swung 27.57 percentage points, moving from a loss to a profit. Education gained 8.11 points to reach a 15.22 percent margin. Accommodation and food service climbed 7.89 points as tourism rebuilt after the pandemic collapse. Financial and insurance, already the most profitable section in 2015, added another 7.74 points. Eleven of eighteen comparable sections widened their margin over the decade. Seven narrowed.
- [Which Thai Industries Hold More Assets Than Companies in 2026](https://maxdatathailand.com/insights/which-thai-industries-hold-more-assets-than-their-company-count-suggests-2026/): Financial and insurance holds 1.8 percent of Thailand's classified companies but an estimated 33.4 percent of national corporate assets, an 18.7 fold overweight. Manufacturing is a smaller version of the same story, at 11.6 percent of companies and 19.5 percent of assets. Wholesale and retail sits closest to proportional, with 36 percent of companies against 20.9 percent of assets. Construction is the mirror image of finance, holding 14.3 percent of companies but only 3.4 percent of assets.
- [Top 10 Companies' Share of Thai Company Revenue (2026)](https://maxdatathailand.com/insights/top-10-companies-share-of-thai-corporate-revenue-2026/): The ten largest Thai companies by revenue report a combined 10.84 trillion baht, about 13.53 percent of Thailand's entire 80.15 trillion baht in reported company revenue as of 7 July 2026. Hua Seng Heng Commoditas, a gold trading house, leads at 3.32 percent of national revenue on its own. PTT ranks second at 2.31 percent. Five of the ten are gold bullion traders, together worth 8.52 percent of national revenue. Three PTT group companies add another 3.78 percent. Ten firms, a rounding error against 1,989,709 registered companies, carry more than one baht in eight.
- [Thailand's Corporate Asset Turnover Ratio in 2026](https://maxdatathailand.com/insights/thailands-corporate-asset-turnover-ratio-2026/): The average Thai company turns over 0.62 baht of revenue for every baht of assets on its books, as of 7 July 2026. National revenue of 80.15 trillion baht runs against an estimated 129.0 trillion baht in company assets. Wholesale and retail trade turns its balance sheet fastest, at 1.62 baht of revenue per baht of assets. Education sits at the other extreme, at just 0.05. The fastest sector outruns the slowest by nearly thirty times.
- [Registered Companies Per Capita by Thai Province (2026)](https://maxdatathailand.com/insights/registered-companies-per-capita-by-thai-province-2026/): Phuket carries 122.23 registered companies for every 1,000 residents as of 7 Jul 2026, 4.06 times Thailand's national average and second only to Bangkok. Bangkok itself leads at 148.97 per 1,000 residents, a 4.95 times multiple, the expected capital effect. Nonthaburi and Chon Buri come next in a near tie, each near 77.7 per 1,000 residents. Samut Prakan follows at 70.68, and Rayong, the leader in revenue per resident, ranks only seventh here at 42.31. Company density and revenue density point to different provinces entirely.
- [Public Administration: Thailand's Smallest Sector, 38 Firms, 2026](https://maxdatathailand.com/insights/public-administration-companies-in-thailand-2026/): 38 companies make up Thailand's entire public administration industry section, the smallest true industry in the registry. Combined they report 267.8 million baht in revenue. Net profit reaches 14.6 million baht. That works out to a 5.45 percent net margin. One dental services firm, Dental Corporation Company Limited, contributes 216.1 million baht of that revenue. That single company accounts for 80.7 percent of the section total. Only 11 of the 38 companies remain active, a 28.9 percent survival rate. The national survival rate is far higher, at 50.0 percent.
- [Other Services in Thailand: 20,455 Firms, Thinnest Margins (2026)](https://maxdatathailand.com/insights/other-services-companies-in-thailand-2026/): Section S, Thailand's catch-all other services category, holds 20,455 registered companies as of 7 Jul 2026. That is more firms than agriculture, arts and entertainment, human health, education, mining or electricity and gas. Yet the section nets just a 0.36 percent margin, against a 4.10 percent national average. Return on assets sits at 0.25 percent and return on equity at 0.67 percent, both near the bottom of the register. Micro firms make up 80.5 percent of the section, well above the 75.1 percent national share, and only 16 companies in it count as large.
- [Average Thai Company Equity: 41.6 Million Baht in 2026](https://maxdatathailand.com/insights/how-much-equity-backs-the-average-thai-company-2026/): Weighting shareholder equity across all 21 industry sections puts the average Thai company's equity at about 41.6 million baht as of 7 July 2026. That works out to roughly 82.6 trillion baht sitting on the books of 1,986,489 classified companies nationwide. Financial and insurance firms average 486.8 million baht each, nearly 12 times the national figure. Just two sections, finance and manufacturing, hold 41.93 percent of all that equity while accounting for only 13.39 percent of companies. Wholesale and retail, home to more than a third of Thailand's companies, sits close to the national average at 36.1 million baht.
- [Energy and Utilities vs Mining: Assets and Margin in Thailand 2026](https://maxdatathailand.com/insights/energy-and-utilities-vs-mining-and-quarrying-in-thailand-2026/): Energy and utilities averages 392.4 million baht in assets per company as of 7 Jul 2026, ahead of mining and quarrying's 337.6 million. Mining flips the order on profitability, posting a 14.04 percent net margin against energy's 11.86 percent. Mining also earns a higher return on assets, 5.23 percent against 3.97 percent, and turns its balance sheet into revenue faster. Energy and utilities counters with sturdier survival, 60.3 percent of its firms still active against just 30.9 percent for mining. A bigger balance sheet does not buy a better margin.
- [Which Thai Industries Punch Above Their Weight in Profit 2026](https://maxdatathailand.com/insights/which-thai-industries-punch-above-their-weight-in-profit-2026/): Financial and insurance holds just 1.79 percent of Thailand's 1,986,489 classified companies, yet it earns 25.52 percent of the country's 3.29 trillion baht in net profit, as of 7 July 2026. That profit share is 14.25 times larger than its company count share, the widest gap in the registry. Electricity and gas ranks second at 7.46 times, then mining and quarrying at 4.62 times. Manufacturing holds the largest profit pool in baht terms but a modest 2.88 times ratio, since it also holds 11.6 percent of all companies. Wholesale and retail trade earns less than half its share of profit.
- [Which Thai Industries Grew Profit Most, 2015 to 2024](https://maxdatathailand.com/insights/which-thai-industries-grew-total-profit-the-most-since-2015-2026/): Manufacturing added more aggregate net profit than any other Thai industry section between 2015 and 2024, up 221.91 billion baht to 899.87 billion baht. Financial and insurance follows, up 208.71 billion baht. Mining's turnaround is the sharpest move in the data. An aggregate loss of 37.78 billion baht in 2015 became an 83.38 billion baht profit in 2024, a swing of 121.16 billion baht. Information and communication is the only major section to lose more than half its profit, falling from 95.88 billion baht to 42.40 billion baht.
- [Thailand's Fastest-Growing Industries by Company Register Share 2026](https://maxdatathailand.com/insights/which-thai-industries-are-gaining-share-of-the-company-register-2026/): Healthcare's share of Thailand's company filing register grew almost sevenfold between 2008 and 2024, rising from 0.41 percent of filers to 1.24 percent. Education more than tripled its own share too, moving from 0.53 percent to 0.79 percent. The two laggards sit at the opposite end. Manufacturing grew only 1.64 times over the period and mining just 1.44 times, both well behind the 2.25 times growth of the entire filing register. Scale and growth do not move together in Thailand's company base.
- [Which Thai Industries Inflate Return on Equity With Debt 2026](https://maxdatathailand.com/insights/where-leverage-inflates-roe-in-thai-industries-2026/): Financial and insurance carries 3.72 baht of assets for every baht of equity, the heaviest debt load of any major Thai industry as of 7 July 2026. Its return on assets is a modest 1.80 percent. That debt turns the return into a 6.71 percent return on equity. Human health needs far less debt, just 1.62 times equity. Its return on assets already reaches 6.71 percent. Its return on equity climbs to a stronger 10.89 percent. The national average equity multiplier is 2.40 times. Return on equity alone cannot tell you which industries earned their number and which borrowed it.
- [Thailand's Filing Base Growth vs Company Formation 2026](https://maxdatathailand.com/insights/is-thailands-filing-base-keeping-pace-with-company-formation-2026/): New company formation in Thailand grew at an 8.38 percent annual pace between 2007 and 2025, close to double the 4.65 percent annual pace of financial statement filings. New companies equaled 9.59 percent of that year's filing count in 2007. By 2025 that share reached 18.01 percent. Filings fell 2.2 percent in 2025, the only year over year drop in the 19 year series, while new company formation rose 5.72 percent. The filing base is not keeping pace with the registration boom.
- [Profit Margin Gaps Within Thai Industry Sectors in 2026](https://maxdatathailand.com/insights/how-wide-is-the-profit-margin-gap-within-thai-industries-2026/): Agriculture's profit margins swing 51.45 percentage points between its narrowest industry codes, the widest gap of any Thai sector with enough codes to compare, as of 7 July 2026. Manufacturing's 379 codes span just 12.6 points, one of the tightest clusters in the economy. Information and communication's 53 codes span 27.14 points, more than double manufacturing's range. A sector label hides real variation, and how much it hides depends on which sector you pick.
- [How Thai Company Profitability Survived Three Crises, 2007-2025](https://maxdatathailand.com/insights/how-thai-company-profitability-weathered-three-crises-2007-2025/): Thai companies' net margin bottomed at 2.58 percent in 2019, the lowest of any year between 2007 and 2025. That trough sits below the 3.27 percent low of the 2008 financial crisis, the 4.22 percent low of the 2011 floods and the 3.61 percent low of the 2020 pandemic year. Return on equity fell to 4.34 percent in 2019, also the weakest reading of the whole period. Profitability recovered within a year after each of the three named shocks, but the deepest scar of the past two decades predates COVID entirely.
- [How Much Profit Do Thai Companies Make Each Day in 2026?](https://maxdatathailand.com/insights/how-much-profit-do-thai-companies-make-each-day-2026/): Thailand's company register produces about 9.01 billion baht of net profit every single day. That comes from 3.29 trillion baht in annual net profit divided across 365 days. Manufacturing, finance and retail trade alone supply 73.9 percent of that daily total. The register turns 4.10 baht of every 100 baht in daily revenue into daily profit. New company formations, by contrast, averaged just 352 a day in 2025, proof that the profit clock and the formation clock run at very different paces.
- [30% of Thailand's Narrow Industries Are One-Company Markets 2026](https://maxdatathailand.com/insights/how-many-of-thailands-narrow-industries-are-one-company-markets-2026/): 29.85 percent of Thailand's narrow five digit industry codes have one company earning at least half of all reported revenue, as of 7 July 2026. That is 357 of 1,196 codes with usable revenue data. 14.55 percent, 174 codes, clear an even higher 80 percent threshold. At the broad 21 section level almost nothing looks this concentrated. The highest real sector is mining at 19.04 percent. Concentration hides inside the narrow codes and disappears once industries get bundled together into sections.
- [Company Size and Survival Rates Across Thai Industries 2026](https://maxdatathailand.com/insights/do-bigger-thai-companies-survive-longer-2026/): Human health and social work posts Thailand's highest industry survival rate at 73.9 percent, with just 1.03 percent of its companies classed large. Manufacturing carries the second highest large company share of any sector at 2.05 percent, yet its survival rate is only 47.3 percent. Across eighteen major industry sections, the relationship between large company share and survival rate is essentially flat, a correlation of 0.07. A bigger mix of large companies does not buy a Thai industry a longer life.
- [Thailand's Most Profitable Industries by Profit Per Company 2026](https://maxdatathailand.com/insights/which-industries-earn-the-most-profit-per-company-in-thailand-2026/): Financial and insurance companies average 32.7 million baht in net profit each, the highest of any industry section in Thailand. Mining and quarrying ranks second at 17.66 million baht per company, then electricity and gas at 15.60 million. Manufacturing, which books the largest total revenue and the largest total net profit of any sector, ranks only fourth per company at 7.39 million baht. Financial and insurance firms average 4.42 times more profit per company than manufacturing firms. Spread that profit across manufacturing's 230,396 companies instead of finance's 35,567, and the average falls hard.
- [Thailand's Water and Waste Sector: 4,818 Firms, 2026](https://maxdatathailand.com/insights/water-supply-and-waste-management-companies-in-thailand-2026/): Thailand's water supply, sewerage and waste management sector, registered as Section E, holds 4,818 companies as of 7 July 2026. Together they report 146.79 billion baht in revenue and 10.72 billion baht in net profit. That is a 7.31 percent net margin, well above the 4.10 percent national average. Inside the section, water utilities alone earn a 28.48 percent margin, beating the sector wide margin of financial and insurance companies. Yet Section E is the one lettered industry on this site still without its own profile page.
- [Why Thai Corporate Revenue Tripled in 2018 Then Fell Back (2026)](https://maxdatathailand.com/insights/the-2018-revenue-spike-in-thai-company-data-explained-2026/): Thailand's reported corporate revenue reached 122.95 trillion baht in statement year 2018, as of 7 Jul 2026. That is 2.77 times the 44.41 trillion baht reported for 2017. It is also 2.56 times the 48.12 trillion baht reported for 2019. The number of reporting companies grew just 7.35 percent that year. Nearly all of the extra 78.54 trillion baht sat in four industry sections, not the whole economy. The spike traces to registry coverage widening, not a real jump in output.
- [Thailand Services vs Industrial Revenue Growth 2015-2025](https://maxdatathailand.com/insights/thailands-services-economy-vs-industrial-economy-2015-2025/): Services revenue grew far faster than industrial revenue in Thailand over the past decade. Grouping the 21 TSIC sections into a services block and an industrial block, services revenue climbed from 21.6 trillion baht in 2015 to 43.4 trillion baht in 2025, up 101.0 percent. Industrial revenue rose from 19.0 trillion baht to 23.9 trillion baht, up just 25.7 percent. Services now make up 64.4 percent of the two blocks combined, up from 53.1 percent a decade earlier. The comparison uses 2015 and 2025 endpoints to sidestep a reporting spike in 2018.
- [Thailand's Most and Least Durable Industry Codes in 2026](https://maxdatathailand.com/insights/thailands-most-and-least-durable-industry-codes-2026/): Industry code 86202 keeps 99.97 percent of its 2,926 registered companies active, the highest survival rate of any Thai TSIC code with at least 400 firms, as of 7 July 2026. Code 03111 sits at the opposite extreme, with only 3.21 percent of its 468 companies still active. That is a 96.76 percentage point gap between two codes drawn from the same national registry. The national average active share is 50.0 percent, so both extremes sit far outside the typical range, and neither is named here, only numbered.
- [Thailand's Missing Middle: Medium Companies by Industry 2026](https://maxdatathailand.com/insights/thailands-missing-middle-companies-by-industry-2026/): Other services counts medium sized companies at just 0.46 percent of its firms, the thinnest middle market of any major Thai industry as of 7 Jul 2026. Water and waste tops the list at 3.78 percent, with manufacturing close behind at 3.52 percent. That gap means water and waste grows medium firms at more than eight times the rate of other services. Nationally, medium companies make up only 1.96 percent of all size banded firms, so most sectors sit below that line, echoing the missing middle pattern documented in SME finance research worldwide.
- [Thailand's Company Birth Rate: 2007 to 2025](https://maxdatathailand.com/insights/thailands-company-birth-rate-2007-2025/): Thailand's company birth rate fell to 8.97 percent in 2025, measuring new registrations against the stock of firms already on the books. That stock stood at 1,433,249 companies going into 2025. The rate was 109.48 percent in 2008, the earliest year the math can run, since few firms existed in the tracked base. It had slid to 16.29 percent by 2021, the same year raw registrations hit a record 151,205. From 2021 to 2025 the rate fell a further 44.94 percent even as registrations stayed strong. Thailand keeps adding companies, just at a slower relative pace each year.
- [How Volatile Is Thai Company Formation, 2007 to 2025](https://maxdatathailand.com/insights/how-volatile-is-thai-company-formation-2007-2025/): New company registrations in Thailand swung from 89,719 in 2017 to a record 151,205 in 2021, then dropped to 119,923 in 2022, a one year fall of 20.69 percent. The 2021 peak was almost exactly five times the 2007 count of 30,227. Annual growth across 2008 to 2025 averaged 8.89 percent but swung by about 10.1 percentage points either side of that average. Two boom years and one hard bust year explain most of the swing, and the cycle runs far choppier than steadier national registries abroad, as of 7 Jul 2026.
- [How Few Industry Codes Hold Half of Thailand's Companies 2026](https://maxdatathailand.com/insights/how-few-industry-codes-hold-half-of-thai-companies-2026/): Forty five industry codes already hold half of Thailand's classified companies. That is just 3.7 percent of the country's 1,228 five digit codes. The cumulative share is 50.26 percent of the 1,986,709 companies with a code, as of 7 July 2026. Round the cutoff to an even 50 codes and the top slice covers 52.70 percent. One single code alone holds 165,550 companies, 8.33 percent of the registry by itself. Meanwhile 485 codes, nearly 40 percent of all codes, hold 100 companies or fewer each. Thailand's business registry looks less like a level field and more like a steep pyramid.
- [Which Thai Provinces Outperform Population in Revenue (2026)](https://maxdatathailand.com/insights/which-thai-provinces-outperform-their-population-in-revenue-2026/): Rayong generates about 4.09 million baht in registered company revenue for every resident, 3.37 times the national average, as of 7 Jul 2026. Samut Prakan follows at 3.49 million baht per resident, 2.88 times the average. Together the two provinces hold about 3.3 percent of Thailand's population. Yet Rayong contributes 4.00 percent of mapped company revenue and Samut Prakan contributes 6.03 percent. Neither is a population magnet like Chiang Mai or Nakhon Ratchasima. Rayong runs the Eastern Seaboard's petrochemical and auto plants, and Samut Prakan runs the port linked industrial estates just outside Bangkok.
- [Fastest Growing Average Firm Size in Thailand 2007 to 2025](https://maxdatathailand.com/insights/which-industries-grew-average-company-size-the-fastest-2007-2025/): Wholesale and retail trade grew its average company revenue faster than any other Thai industry over the last 18 statement years, up 118.8 percent as of 7 July 2026. The typical wholesale and retail firm reported 65.1 million baht in 2007 and 142.4 million baht in 2025. Mining and quarrying comes second at 60.3 percent. At the other end, human health and social work shrank 34.8 percent, real estate shrank 8.9 percent, and professional, scientific and technical services shrank 24.2 percent, because new firms piled in faster than revenue did.
- [The Giant vs the Average Firm, by Thai Industry 2026](https://maxdatathailand.com/insights/the-giant-and-the-typical-firm-by-thai-industry-2026/): Wholesale and retail trade shows the widest gap of any Thai industry section, where the top firm earns 58,694 times the sector's average company revenue as of 7 July 2026. Hua Seng Heng Commoditas Company Limited reported 5.56 trillion baht in revenue. The sector's average company revenue is just 94.67 million baht. Administrative and support follows at 9,694 times. Manufacturing ranks third at 8,926 times. Water and waste management shows the narrowest gap among sizeable sectors, at 129 times. An industry's size tells you little about how lopsided it is inside.
- [Thai Financial Statement Filings by Year: 2007 to 2025](https://maxdatathailand.com/insights/thai-financial-statement-filings-by-year-2007-2025/): The number of Thai companies filing a financial statement each year climbed from 315,278 in 2007 to a record 730,001 in 2024, as of 7 July 2026. That is a 131.5 percent increase over 17 years. In 2025 the count slipped to 713,946, the first annual decline in the entire series. The drop came to 2.2 percent. Every other year from 2008 through 2024 grew over the one before it. The average annual pace across the full stretch works out to 4.6 percent.
- [Most Capital-Intensive Industries in Thailand by Assets (2026)](https://maxdatathailand.com/insights/most-capital-intensive-industries-in-thailand-2026/): Financial and insurance companies hold an average of 1.81 billion baht in assets each, the highest of any industry section in Thailand. That average is 21.5 times the mean of the other 20 sections, and more than four times the second ranked sector, electricity and gas, at 392.4 million baht. Manufacturing averages 163.8 million baht. Wholesale and retail trade, the largest sector by company count, averages just 56.4 million baht. Capital intensity varies far more across Thai industries than revenue or profit margin alone would suggest.
- [Is Thai Company Formation Speeding Up or Slowing Down in 2026?](https://maxdatathailand.com/insights/is-thai-company-formation-speeding-up-or-slowing-down-2026/): Thai company formation is slowing on average even though the year to year path has turned into a rollercoaster. Annual growth averaged 11.62 percent a year from 2008 through 2019. It averaged 3.42 percent a year from 2020 through 2025, less than a third of the earlier pace. Growth hit 23.51 percent in 2021, the fastest year on record. It then reversed into a 20.69 percent contraction in 2022, the sharpest single year drop in the series. A partial rebound followed, with 5.72 percent growth in 2025. Counting new companies each year hides this deceleration that the growth rate reveals.
- [How Many Industry Codes Sit Inside Each Thai Sector, 2026](https://maxdatathailand.com/insights/how-many-sub-industries-make-up-each-thai-sector-2026/): Manufacturing spans 421 distinct 5-digit industry codes, more than any of Thailand's 21 lettered business sectors, as of 7 July 2026. Wholesale and retail trade follows with 200 codes. Real estate holds only 9 codes despite housing 149,608 companies. Households and extraterritorial organizations sit at the bottom with 3 and 2 codes. Across the whole registry, 1,228 distinct industry codes exist. The typical sector contains just 27 of them.
- [Education vs Healthcare Companies in Thailand: Size and ROE 2026](https://maxdatathailand.com/insights/education-vs-healthcare-companies-in-thailand-2026/): Healthcare companies in Thailand average 6.7 times the revenue of education companies, as of 7 July 2026. The human health and social work sector reports 517.42 billion baht in total revenue against 62.01 billion baht for education. Education still wins on return on equity, posting 12.1 percent against 10.9 percent for healthcare. Healthcare wins comfortably on return on assets, at 6.71 percent against just 0.71 percent for education. Bigger does not mean more profitable, and profitable does not mean efficient with assets.
- [Construction vs Real Estate Companies in Thailand 2026](https://maxdatathailand.com/insights/construction-vs-real-estate-companies-in-thailand-2026/): Construction and real estate are Thailand's two property-adjacent sectors, yet they sit at opposite ends of the profit table. Construction spans 283,534 registered companies, nearly twice real estate's 149,608. Construction's aggregate net margin is just 2.3 percent, while real estate holds 7.7 percent, more than three times higher. Real estate companies also average 643,905 baht in net profit each, over three times construction's 189,328 baht average, despite almost identical average revenue per company.
- [Thai Companies' Average Assets Per Firm: 2007 to 2025](https://maxdatathailand.com/insights/are-thai-companies-getting-bigger-assets-per-firm-2007-2025/): Average assets per filing Thai company reached about 144 million baht in 2025, up from roughly 91 million baht in 2007. That is a 57.7 percent rise in typical firm size across eighteen years. Over the same span the number of companies filing a statement grew from 315,278 to 713,946, more than doubling. Total assets on file climbed 257 percent, so more of that growth came from new filers joining the registry than from existing firms swelling in size.
- [Thailand Industries Ranked by Total Profit in Baht, 2026](https://maxdatathailand.com/insights/which-industries-generate-the-most-profit-in-thailand-2026/): Manufacturing produced 1.10 trillion baht in net profit across Thailand's registered companies, more than any other industry, as of 7 July 2026. Financial and insurance ranks second at 839.19 billion baht, even though its 25.40 percent net margin is nearly six times manufacturing's 4.37 percent. Wholesale and retail trade lands third at 493.82 billion baht on a margin of just 1.27 percent. The top three sections alone generate 73.9 percent of all profit summed across Thailand's 21 industry sections. Scale, not margin, decides who actually earns the most money in the Thai economy.
- [Thailand's Smallest Industries by Company Count in 2026](https://maxdatathailand.com/insights/thailands-smallest-business-sectors-2026/): Just 74 companies in Thailand fall under public administration, households as employers, and extraterritorial organizations combined, sections O, T and U. Thailand has 1,989,709 registered companies as of 7 July 2026. Those three sections equal just 0.0037 percent of that total. Water supply and waste management, section E, adds only 4,818 more, still under a quarter of one percent. Electricity, gas, steam and air conditioning supply, section D, is the fifth smallest at 7,833. Together the five smallest sections hold 12,725 companies, under two percent of the size of wholesale and retail trade alone.
- [Thailand Company Formation Trends Through the Pandemic 2026](https://maxdatathailand.com/insights/thailand-company-formation-during-the-pandemic-2026/): New company registrations in Thailand hit a two-decade high of 151,205 in 2021, not a Covid slowdown, a 35.9 percent jump from 111,284 in 2019. Registrations then fell 25.6 percent to a trough of 112,461 in 2023. By 2025 the count recovered to 128,617, still 14.9 percent below the 2021 peak but 15.6 percent above the last pre-pandemic year. The pandemic years were a boom, then a bust, not the slump most people assume.
- [Financial Sector vs Real Estate Profitability in Thailand 2026](https://maxdatathailand.com/insights/financial-sector-vs-real-estate-profitability-2026/): Thailand's financial sector posts a 25.4 percent net margin as of 2 July 2026. Real estate posts 7.7 percent, roughly a third as much. Finance reaches that margin with only 35,567 registered companies. Real estate carries 149,608 registered companies, more than four times as many. The average finance company books about 92.9 million baht in yearly revenue. The average real estate company books about 8.4 million baht. Scale sits with real estate. Profit per baht sits with finance.
- [Big Business vs Small Business by Industry in Thailand 2026](https://maxdatathailand.com/insights/big-business-vs-small-business-by-industry-in-thailand-2026/): Large companies make up just 0.70 percent of Thailand's 1,986,709 size-classified companies as of 7 July 2026. That rate more than triples in energy and utilities, where 2.44 percent of firms are large, about one in every 41 companies. Manufacturing follows at 2.05 percent. At the other end, other services counts large firms at just 0.08 percent, roughly one in 1,278, and education sits at 0.13 percent, about one in 772. Scale concentrates in a handful of capital-heavy sectors and stays almost invisible everywhere else.
- [Wholesale and Retail: Thailand's Biggest Sector 2026](https://maxdatathailand.com/insights/wholesale-and-retail-thailands-biggest-sector-2026/): Wholesale and retail is Thailand's largest sector, with 715,976 registered companies as of 2 July 2026. That is 36.0 percent of all classified firms, so one in three companies is a trader. The sector reports 34.93 trillion baht of revenue, 45.6 percent of the national total. Yet its net profit margin is just 1.40 percent, the thinnest of any major sector. Scale here does not buy profit.
- [Who Leads Each Industry in Thailand by Revenue (2026)](https://maxdatathailand.com/insights/who-leads-each-industry-in-thailand-2026/): Every major Thai industry has one revenue leader, and the ten of them map who runs corporate business here. PTT tops manufacturing, a sector of 230,396 firms. Hua Seng Heng Commoditas leads wholesale and retail, the most crowded field at 715,976 companies. Central Pattana runs real estate, Minor International runs hospitality, and Bangkok Dusit Medical Services leads health. Mining is the smallest arena mapped, at 8,231 firms. Ten sectors, ten champions, as of 2 July 2026.
- [Which Thai Business Sectors Lose Money by Net Margin 2026](https://maxdatathailand.com/insights/which-thai-business-sectors-lose-money-2026/): Two of Thailand's business sectors reported an aggregate net loss as of 2 July 2026. Arts, entertainment and recreation came in at a net margin of -0.24 percent. Other service activities finished at -0.07 percent. Every other section turned a profit. The national aggregate margin sits at a positive 4.42 percent. Financial and insurance leads the whole economy at 26.90 percent. A sector losing money outright is rare in the registry, which makes these two worth a close look.
- [Thai Company Survival Rates by Industry in 2026](https://maxdatathailand.com/insights/which-industries-survive-and-which-fail-in-thailand-2026/): Half of Thailand's registered companies are still alive, a national survival rate of 50.0 percent as of 2 July 2026. Survival splits hard by sector. Human health and social work keeps 73.9 percent of its firms active, the best of any section. Mining and quarrying keeps only 30.9 percent, the worst. The three largest sectors by count, trade, construction and manufacturing, all sit below the national line.
- [Which Industries Have the Most Companies in Thailand? (2026)](https://maxdatathailand.com/insights/which-industries-have-the-most-companies-in-thailand-2026/): Wholesale and retail trade is by far Thailand's largest industry, with 715,976 registered companies, or 36 percent of all classified firms as of 2 July 2026. Construction ranks second with 283,534 and manufacturing third with 230,396. Those three sectors hold 61.9 percent of the country's companies between them.
- [Which Thai Industries One Company Dominates (2026)](https://maxdatathailand.com/insights/which-industries-are-dominated-by-one-company-in-thailand-2026/): PTT Exploration and Production holds 19.68 percent of all mining and quarrying revenue, the steepest single-company dominance of any measured Thai sector as of 2 July 2026. Hua Seng Heng Commoditas is close behind, holding 15.91 percent of wholesale and retail trade, the country's largest sector by company count. Administrative and support and information and communication follow above 13 percent. The average top firm across 18 measured sections holds just 7.81 percent of its sector. Accommodation and food service sits at the other end, where Minor International holds only 2.07 percent. Field size and dominance move on separate tracks.
- [Which Decade Created the Most Thai Companies 2026](https://maxdatathailand.com/insights/which-decade-created-the-most-thai-companies-2026/): The 2020s have already created 756,290 new Thai companies, more than any decade on record. The full 2010s produced 706,885 across ten years. That leaves the half finished 2020s ahead by 49,405 companies in six years rather than ten. The year 2021 set the single year record at 151,205 registrations. Thailand now holds 1,989,709 registered companies in total. Formation is accelerating, not settling.
- [Where Thai Company Profits Come From in 2026](https://maxdatathailand.com/insights/where-thai-company-profits-come-from-2026/): Two industries produce 62.2 percent of all company profit in Thailand as of 2 July 2026. Manufacturing alone accounts for 32.5 percent of the national total of 3.39 trillion baht. Financial and insurance adds another 29.7 percent. Wholesale and retail, the third-place sector, trails far behind at 14.4 percent. Every other sector splits the remaining scraps.
- [What Share of Thai Companies File Financial Statements? (2026)](https://maxdatathailand.com/insights/what-share-of-thai-companies-report-financials-2026/): Of Thailand's 1,989,709 registered companies, about 1,239,700 have a financial statement on file as of 2 July 2026, a 62.3 percent reporting rate. The other 750,009 companies, roughly 37.7 percent, have no statement on record. Any national revenue or profit total is therefore built from a little under two thirds of the register.
- [Thailand Transportation and Logistics Sector Size 2026](https://maxdatathailand.com/insights/transportation-and-logistics-companies-in-thailand-2026/): Thailand's transportation and storage sector counts 85,273 companies as of 2 July 2026. That is 4.3 percent of all classified firms. Together they reported about 2.14 trillion baht in revenue. The sector earns a 5.89 percent net margin and a 10.37 percent return on equity, one of the highest of any sector. Reported revenue grew 56.1 percent across the past decade. Thai Airways International leads the field by revenue.
- [Thailand's Micro-Business Economy: 1.5 Million Firms in 2026](https://maxdatathailand.com/insights/the-micro-business-economy-of-thailand-2026/): Thailand has 1,495,029 micro companies as of 2 July 2026, which is 75.3 percent of all 1,986,709 classified firms. Small firms add another 439,043, so micro and small together reach 97.4 percent of the registry. Medium companies number just 38,827, and only 13,810 firms are large. Three of every four Thai companies are the smallest kind there is.
- [The Eastern Economic Corridor of Thailand in Numbers 2026](https://maxdatathailand.com/insights/the-eastern-economic-corridor-of-thailand-in-numbers-2026/): The Eastern Economic Corridor is home to 173,905 registered companies as of 2 July 2026. That is 8.7 percent of every company in Thailand. Those same three provinces booked 7.86 trillion baht in revenue, which is 10.3 percent of the national total. Chon Buri, Rayong and Chachoengsao punch above their count. Fewer than nine companies in a hundred sit here, yet they turn over more than one baht in ten.
- [Thailand's Regions Compared by Business Activity 2026](https://maxdatathailand.com/insights/thailands-regions-compared-by-business-2026/): Bangkok holds 40.9 percent of Thailand's registered companies as of 2 July 2026. That is one province out-registering every multi province region in the country. On revenue the gap is wider: Bangkok books 61.5 percent of the national total. Central Thailand ranks second with 404,768 companies spread across 14 provinces. The Northeast covers 20 provinces yet earns just over 3 percent of revenue. Business here is not spread across the map. It is stacked on the capital.
- [Thailand's Financial and Insurance Sector: Profit in 2026](https://maxdatathailand.com/insights/thailands-financial-and-insurance-sector-2026/): Financial and insurance posts a 26.9 percent net profit margin, the highest of any major sector in Thailand as of 2 July 2026. The sector counts only 35,567 companies, about 1.8 percent of all classified firms. It still books 3.74 trillion baht in revenue, near 4.9 percent of the national total. Its margin runs close to double that of the next sector, mining at 13.49 percent. Small in number, outsized in profit.
- [Thailand Tourism and Hospitality Business Size in 2026](https://maxdatathailand.com/insights/thailand-tourism-and-hospitality-business-2026/): Thailand's accommodation and food service sector holds 83,598 registered companies as of 2 July 2026. That works out to 4.2 percent of all classified firms. The sector reported about 0.91 trillion baht in revenue. Its revenue climbed 88.8 percent over the decade, from 394.6 to 745.3 billion baht. Net profit margin sits at 4.96 percent. The survival rate of 58.1 percent beats the 50.0 percent national average. Minor International leads the sector by revenue.
- [Thai Company Revenue Over 20 Years: 2007 to 2025 (2026)](https://maxdatathailand.com/insights/thai-company-revenue-over-20-years-2007-to-2025/): Reported company revenue in Thailand grew from 23.26 trillion baht in 2007 to 59.81 trillion baht in 2025. That is a 157 percent gain over 18 statement years, about 5.4 percent compounded annually. Reported net profit climbed faster, from 0.98 trillion to 2.88 trillion baht. The aggregate net margin barely moved, at 4.2 percent in 2007 and 4.8 percent in 2025. The economy more than doubled on paper while keeping the same thin slice of profit.
- [Thai Company Formation: The 20-Year Trend (2007 to 2025)](https://maxdatathailand.com/insights/thai-company-formation-trend-2007-2025/): Thailand registered 128,617 new companies in 2025, up from 30,227 in 2007. New company formation grew at roughly 8 percent a year across the period and reached a record 151,205 registrations in 2021. Even after the 2021 peak, yearly formation has stayed well above its pre-pandemic level.
- [Southern Thailand Registered Companies by Province in 2026](https://maxdatathailand.com/insights/southern-thailand-business-in-2026/): Southern Thailand holds 179,033 registered companies as of 2 July 2026, which is 9.0 percent of the national total. Those firms report 2.32 trillion baht in revenue, only 3.0 percent of the country's turnover. Three provinces dominate the region. Phuket, Surat Thani and Songkhla together hold 121,261 companies, 67.7 percent of the South. The rest of the 14 provinces split what remains.
- [Thailand's Smallest Business Provinces by Company Count (2026)](https://maxdatathailand.com/insights/smallest-business-provinces-in-thailand-2026/): Mae Hong Son has 1,569 registered companies, the fewest of any classified province in Thailand, as of 2 July 2026. Uthai Thani follows at 2,099 and Satun at 2,110. Bangkok alone holds 812,799 companies, about 518 times Mae Hong Son's count. The ten smallest provinces combined hold only 23,608 companies, just 1.19 percent of the national total. Company count and business intensity do not always move together. Chai Nat, the tenth smallest province by count, still books 27.09 million baht of revenue per company, the highest among the ten.
- [Richest Provinces in Thailand by Company Revenue (2026)](https://maxdatathailand.com/insights/richest-provinces-in-thailand-by-revenue-2026/): Bangkok generates the most company revenue in Thailand, 47.13 trillion baht as of 2 July 2026, which is 61.5 percent of the national total. Samut Prakan ranks second at 4.82 trillion baht, then Chon Buri at 3.79 trillion. Ranking by revenue instead of company count reshuffles the map. Rayong holds only 33,083 companies yet books 3.22 trillion baht, the richest firms per company of any large province.
- [Revenue Concentration Among Thai Companies 2026](https://maxdatathailand.com/insights/revenue-concentration-among-thai-companies-2026/): Thailand's ten largest companies produce 14.1 percent of all reported company revenue as of 2 July 2026. Those ten firms are 0.0008 percent of the 1,239,700 companies that reported. Total reported revenue reached 76.62 trillion baht. Bangkok alone holds 61.5 percent of it. Micro and small firms make up 97.4 percent of all companies. Thai business is a long tail with a very heavy head.
- [Return on Equity by Industry in Thailand (2026)](https://maxdatathailand.com/insights/return-on-equity-by-industry-in-thailand-2026/): Education earns the highest return on equity in Thailand at 12.31 percent as of 2 July 2026. Human health follows at 11.17 percent, then transportation and storage at 10.37 percent. Nine of the fifteen tracked sectors beat the national average of 6.30 percent. Construction sits last at 2.15 percent. Profit margin ranked these sectors one way. How hard each one works the owners' money looks nothing alike.
- [Real Estate Companies in Thailand: Margin and Health 2026](https://maxdatathailand.com/insights/real-estate-companies-in-thailand-2026/): Thailand counts 149,608 real estate companies as of 2 July 2026, the fourth largest sector by count. Those firms make up 7.5 percent of all classified companies. The sector earns a 7.92 percent net margin, well above the 4.42 percent national average. Its 62.4 percent survival rate is among the highest of any sector. Yet reported revenue is only 1.24 trillion baht, just 1.6 percent of the national total. Real estate keeps assets, it does not churn them.
- [Professional and Technical Services in Thailand: Size, Margin 2026](https://maxdatathailand.com/insights/professional-and-technical-services-in-thailand-2026/): Thailand counts 138,962 registered professional, scientific and technical services companies as of 2 July 2026. That is 7.0 percent of all classified firms, the fifth largest sector by count. Together they reported about 1.05 trillion baht in revenue. The net profit margin is 12.68 percent, the fourth highest of any sector. Only finance, mining and education keep more of each baht. This is where the knowledge economy earns its keep.
- [Northern Thailand: 170,661 Companies by Province 2026](https://maxdatathailand.com/insights/northern-thailand-business-in-2026/): Northern Thailand holds 170,661 registered companies as of 2 July 2026. That is about 8.6 percent of the national total. The region turns over 2.00 trillion baht in revenue. That revenue is only 2.6 percent of the country. One city carries the region: Chiang Mai counts 65,164 companies. That figure is 38.2 percent of the North. Chiang Rai is a distant second at 18,652. The other fifteen provinces split the rest thinly.
- [Northeast Isan Business in Thailand: The Numbers, 2026](https://maxdatathailand.com/insights/northeast-isan-business-in-thailand-2026/): Thailand's Northeast holds 179,476 registered companies as of 2 July 2026, which is 9.0 percent of the national total. Those companies book 2.34 trillion baht in revenue, only 3.1 percent of the country's total. This is the largest and most populous of Thailand's regions. Bangkok alone registers 812,799 companies, about 4.5 times the entire Northeast. Population and company count do not track together here.
- [Most Profitable Industries in Thailand by Net Margin (2026)](https://maxdatathailand.com/insights/most-profitable-industries-in-thailand-2026/): Financial and insurance is Thailand's most profitable industry, earning a 26.9 percent net margin as of 2 July 2026. Mining, education and professional services follow, each above 12.68 percent. Wholesale and retail, the largest sector by company count, sits at the bottom with a margin of just 1.4 percent. Scale and profitability rarely move together.
- [Most Efficient Provinces in Thailand by Revenue per Company 2026](https://maxdatathailand.com/insights/most-efficient-provinces-in-thailand-by-revenue-2026/): Rayong generates about 97.5 million baht of revenue per registered company, the most of any Thai province as of 2 July 2026. Phra Nakhon Si Ayutthaya ranks second at about 73.2 million. Bangkok, home to more companies than anywhere else, ranks only third at about 58.0 million. The national average sits near 61.8 million baht per company. Where owners register and where the money is made are two different maps.
- [Mining and Quarrying in Thailand: High Margin, Low Survival 2026](https://maxdatathailand.com/insights/mining-and-quarrying-companies-in-thailand-2026/): Thailand's mining and quarrying sector runs a 13.49 percent net profit margin, the second highest of any sector as of 2 July 2026. Only 30.9 percent of its companies are still active, the lowest survival rate in the economy. The sector holds 8,231 registered firms. It reported about 0.43 trillion baht in revenue. Return on equity sits at 7.40 percent. High reward meets high mortality.
- [Manufacturing vs Wholesale and Retail Trade in Thailand 2026](https://maxdatathailand.com/insights/manufacturing-vs-wholesale-and-retail-compared-2026/): Wholesale and retail trade runs 715,976 companies against manufacturing's 230,396, a gap of 3.1 times. It also books 38.8 percent more total revenue, 34.93 trillion baht versus 25.16 trillion baht. Yet manufacturing turns a 4.38 percent net margin, more than three times wholesale and retail's 1.4 percent. Scale and profit point in opposite directions for Thailand's two biggest sectors.
- [Manufacturing Companies in Thailand: Count and Revenue (2026)](https://maxdatathailand.com/insights/manufacturing-companies-in-thailand-2026/): Thailand has 230,396 registered manufacturing companies as of 2 July 2026, about 11.6 percent of all classified firms. Yet manufacturing carries 32.8 percent of the country's reported revenue, roughly 25.2 trillion baht. That gap between a modest share of companies and a large share of revenue is what makes manufacturing the heavyweight of the Thai economy.
- [Largest Companies in Thailand by Revenue (2026)](https://maxdatathailand.com/insights/largest-companies-in-thailand-by-revenue-2026/): Hua Seng Heng Commoditas reported the highest revenue of any Thai company, at about 2.7 trillion baht as of 2 July 2026, ahead of PTT at 1.8 trillion. The most striking pattern in the top ten is gold. Five of the ten largest companies by revenue are gold traders, together moving roughly 6.8 trillion baht. Revenue here reflects trading throughput, not profit.
- [Thai Tech and Telecom Revenue: Growing or Shrinking in 2026](https://maxdatathailand.com/insights/is-thai-tech-and-telecom-growing-or-shrinking-2026/): By reported revenue, Thailand's information and communication sector shrank 23.2 percent over the decade, dropping from 844.8 billion baht in 2015 to 648.6 billion baht in 2025. It is the rare sector to move backward while almost everything else grew. The sector still holds 52,537 companies and a 55.3 percent survival rate, above the national 50.0 percent. The decline is in reported revenue and may reflect where telecom income is booked, not a real collapse.
- [How Profitable Are Thai Companies? Margin, ROA and ROE (2026)](https://maxdatathailand.com/insights/how-profitable-are-thai-companies-2026/): Across all filed financial statements, Thai companies earn an aggregate net margin of 4.42 percent, a return on assets of 2.62 percent and a return on equity of 6.3 percent as of 2 July 2026. Profitability has drifted down over the past decade. Return on equity peaked above 13.3 percent in the early 2010s and now sits near 7.79 percent. Thai firms have grown larger while their returns have thinned.
- [How Much Revenue Do Thai Companies Generate? (2026)](https://maxdatathailand.com/insights/how-much-revenue-do-thai-companies-generate-2026/): Thai companies report about 76.6 trillion baht in combined revenue and 3.4 trillion baht in net profit as of 2 July 2026, drawn from 1,239,700 filed financial statements. Revenue is concentrated. Wholesale and retail plus manufacturing alone account for 78.4 percent of the total. The headline number is huge, but it rests on a narrow set of high-volume sectors.
- [How Many Thai Companies Are Actually Active? 993,373 in 2026](https://maxdatathailand.com/insights/how-many-thai-companies-are-actually-active-2026/): Thailand lists 1,989,709 registered companies as of 2 July 2026. Only 993,373 of them are actually active. That is 50.0 percent of every company carrying an activity status. Another 993,336 sit dormant, still on the register but showing no trading signal. Just 1,239,700 companies have ever filed a financial statement. A registration count is not an activity count, and in Thailand the gap is exactly half.
- [New Companies Thailand Adds Each Day: 352 in 2026](https://maxdatathailand.com/insights/how-many-new-companies-does-thailand-add-each-day-2026/): Thailand added 128,617 new companies in 2025, which works out to about 352 a day as of 2 July 2026. That is one fresh registration roughly every four minutes, around the clock. The daily rate has run above 300 every year since 2021. The record still belongs to 2021, when 151,205 new companies arrived, about 414 a day. Formation has grown at roughly 8.4 percent a year since 2007. The register now holds 1,989,709 companies in total.
- [How Many Thai Directors Control Multiple Companies in 2026](https://maxdatathailand.com/insights/how-many-directors-control-multiple-companies-in-thailand-2026/): Most Thai company directors control exactly one company, but 513,111 of them are linked to two or more as of 2 July 2026. That is 16.0 percent of all 3,215,544 director records. A smaller group of 45,135 directors is linked to five or more companies. Only 7,682 people reach ten or more. The single most connected director record touches 930 companies. Control thins out fast at the top.
- [How Many Companies Are Registered in Thailand? (2026)](https://maxdatathailand.com/insights/how-many-companies-are-registered-in-thailand-2026/): Thailand has 1,989,709 registered companies as of 2 July 2026, and 1,239,700 of them (62.3 percent) have filed financial statements. Together those companies report about 76.6 trillion baht in annual revenue. Wholesale and retail trade is the single largest sector, with 715,976 companies, or 36 percent of the whole registry.
- [How Concentrated Is Thai Revenue by Sector in 2026](https://maxdatathailand.com/insights/how-concentrated-is-thai-revenue-by-sector-2026/): Two industry sections book 78.4 percent of all company revenue in Thailand as of 2 July 2026. Wholesale and retail alone reports 34.93 trillion baht, or 45.6 percent of the national total. Manufacturing adds 25.16 trillion baht, another 32.8 percent. The next 19 sections split the remaining 16.53 trillion baht between them. Revenue in Thailand is not spread across the economy. It piles up in two places.
- [Thai Business by Province: Five Provinces Hold 61% in 2026](https://maxdatathailand.com/insights/how-concentrated-is-thai-business-by-province-2026/): Five provinces hold 61.4 percent of Thailand's registered companies as of 2 July 2026. Bangkok alone holds 40.9 percent, the most concentrated province in the country. The top five together count 1,221,057 firms. The other 72 provinces share just 38.6 percent between them. Business in Thailand is not spread across the map. It clusters hard around the capital.
- [Highest Average Revenue Per Company by Industry, Thailand 2026](https://maxdatathailand.com/insights/highest-average-revenue-per-company-by-industry-2026/): Manufacturing companies average 177.7 million baht in revenue each, the highest of Thailand's 21 industry sections as of 2 July 2026. Financial and insurance follows at 152.6 million baht, then electricity and gas at 151.0 million baht. Other services sits at the bottom among sections with a meaningful filer base, at just 6.4 million baht per company, with education close behind at 6.5 million baht. That is a 28.0 times gap between the biggest and smallest average firm size in the economy. Capital intensity, not company count, decides how big the typical firm in a sector is.
- [Healthcare Companies in Thailand: Size and Survival 2026](https://maxdatathailand.com/insights/healthcare-companies-in-thailand-2026/): Thailand counts 17,294 registered healthcare companies as of 2 July 2026, just 0.9 percent of all classified firms.

It also posts the highest return on assets in the economy at 6.88 percent. Reported sector revenue reached about 515.2 billion baht. The revenue trajectory more than doubled across ten years, up 112.8 percent.
- [Greater Bangkok's Share of Thai Business by Revenue 2026](https://maxdatathailand.com/insights/greater-bangkok-share-of-thai-business-2026/): Greater Bangkok holds 57.9 percent of Thailand's registered companies as of 2 July 2026. The six provinces of the Bangkok Metropolitan Region count 1,152,423 firms. They also book 75.3 percent of all company revenue, 57.71 trillion baht of the national 76.62 trillion. The revenue share runs far ahead of the company share. Each Greater Bangkok firm earns about 2.2 times the revenue of a firm elsewhere. Thailand's economy is a city-state with a very large hinterland.
- [Fastest Growing Industries in Thailand: Revenue 2015 to 2025](https://maxdatathailand.com/insights/fastest-growing-industries-in-thailand-2015-to-2025/): Agriculture grew its reported revenue fastest of any Thai industry over the decade, up 122.6 percent from 2015 to 2025. Human health and social work followed at 112.8 percent, more than doubling. Wholesale and retail trade added 96.5 percent on a far larger base. Information and communication was the only major sector to shrink, down 23.2 percent. Figures are reported revenue as of 2 July 2026.
- [Energy and Utilities Companies in Thailand 2026](https://maxdatathailand.com/insights/energy-and-utilities-companies-in-thailand-2026/): Thailand's electricity, gas and utilities sector holds just 7,833 companies as of 2 July 2026, only 0.4 percent of all classified firms. It earns an 11.62 percent net profit margin, far above the 4.42 percent national average. Reported revenue reaches about 0.84 trillion baht. Reported net profit sits near 97.8 billion baht. Survival runs at 60.3 percent, above the national 50.0 percent. Few companies, deep pockets.

The sector earns a 12.31 percent return on equity, the highest of any major industry section. Its net profit margin of 13.12 percent ranks third in the whole economy. Return on assets sits at only 0.71 percent, held down by heavy school buildings and land. Reported sector revenue grew 87.1 percent over the past decade. Small, asset heavy, and quietly very profitable.
- [Construction Companies in Thailand: Count and Survival 2026](https://maxdatathailand.com/insights/construction-companies-in-thailand-2026/): Thailand has 283,534 registered construction companies as of 2 July 2026, the second largest sector by count. That count is 14.3 percent of all classified firms. Building is a crowded trade with a thin cushion. Only 42.5 percent of construction companies are still active, the second weakest survival rate in the economy after mining. The sector reports a net profit margin of 1.95 percent. Return on equity sits at 2.15 percent. Scale here does not buy safety.
- [Company Size Distribution in Thailand: Micro to Large (2026)](https://maxdatathailand.com/insights/company-size-distribution-in-thailand-2026/): Thailand's company base is overwhelmingly small. Micro firms account for 75.3 percent of all registered companies as of 2 July 2026, and once small firms are added, the two groups make up 97.4 percent of the total. Large companies number just 13,810, or 0.7 percent. The Thai economy runs on a very long tail of tiny businesses.
- [Companies by Province in Thailand: Where Business Registers (2026)](https://maxdatathailand.com/insights/companies-by-province-in-thailand-2026/): Bangkok is home to 812,799 registered companies, about 40.9 percent of Thailand's 1,989,709 total as of 2 July 2026. Chon Buri ranks a distant second with 127,023. The five busiest provinces together hold 61.4 percent of every registered company in the country. Business in Thailand is heavily clustered around the capital and its neighbours.
- [Chiang Mai vs Phuket: Registered Companies 2026](https://maxdatathailand.com/insights/chiang-mai-vs-phuket-business-comparison-2026/): Chiang Mai wins. It holds 65,164 registered companies against Phuket's 52,557 as of 2 July 2026. That is a lead of 12,607 firms. Chiang Mai also books more revenue, 527.2 billion baht to Phuket's 389.3 billion. Each Chiang Mai company earns about 8.09 million baht, versus 7.41 million in Phuket. Both provinces run on tourism, accommodation, food service and real estate rather than factories.
- [Central Thailand Share of Thai Business by Province 2026](https://maxdatathailand.com/insights/central-thailand-the-industrial-heartland-2026/): Central Thailand outside Bangkok holds 404,768 companies as of 2 July 2026, one registered firm in five nationwide.

Samut Prakan follows with 97,609 firms and 4,820 billion baht of revenue. The capital does not stand alone.
- [Bangkok vs the Rest of Thailand: Companies and Revenue (2026)](https://maxdatathailand.com/insights/bangkok-vs-the-rest-of-thailand-2026/): Bangkok holds 40.9 percent of Thailand's registered companies but a much larger 61.5 percent of all reported revenue as of 2 July 2026. The capital's 812,799 companies generate about 47.1 trillion baht, against 29.5 trillion for the other 1,176,910 companies across the country. Bangkok is not just the biggest market, it is where the revenue concentrates.
- [Average Revenue Per Company in Thailand 2026](https://maxdatathailand.com/insights/average-revenue-per-company-in-thailand-2026/): The average Thai company reports about 61.8 million baht in revenue as of 2 July 2026. That number is a mirage. It comes from spreading 76.6 trillion baht of reported revenue across 1,239,700 companies that filed a statement. A small set of giants drags the mean upward. About 75.3 percent of all companies are micro-sized, so the typical firm earns far below 61.8 million baht. The average describes almost no one.
- [Thailand's Arts and Entertainment Sector: Revenue and Margin 2026](https://maxdatathailand.com/insights/arts-entertainment-and-recreation-companies-in-thailand-2026/): Thailand's arts, entertainment and recreation sector counts 18,486 registered companies and 133.6 billion baht in reported revenue as of 2 July 2026.

Only one other section, other service activities, also loses money on average. Micro companies make up 81.5 percent of the sector, well above the national micro share of 75.3 percent.

Just 19,259 firms sit in the sector, 1.0 percent of all classified companies as of 2 July 2026. Those firms reported about 485.5 billion baht of revenue. The sector keeps a thin 2.63 percent net margin. Farming revenue still grew 122.6 percent across the decade, the fastest climb of any sector.

That is 5.1 percent of all classified firms, the sixth largest sector by company count. Together they report about 1.10 trillion baht in revenue. Their net profit margin is a thin 4.33 percent. Sector revenue grew 62.4 percent across the past decade. This is the quiet machinery behind staffing, cleaning, security and call centres.
