Bangkok is the economic center of Thailand, dominating the country's economy and dwarfing any other urban centres. Development continues to pour in to Bangkok mostly neglecting the rest of the nation. Its combined economic output is roughly 140 billion dollars in purchasing power parity terms, which accounts for roughly 16 percent of Thailand's GDP also in PPP terms. However, there is a large discrepancy between statisticians and economists who claim that Bangkok accounts for nearly 75 percent of Thailand's service sector which accounts for 45.2 percent of Thailand's 590 billion dollar economy. With the given GDP of the city, the estimates for per capita income is roughly 20,000 dollars. More realistic but unclaimed estimates put the city's output as high as 210 billion dollars, accounting for 38 percent of national income and per capita income at 33,000 dollars.
The Stock Exchange of Thailand, or the SET is located on Ratchadaphisek Road in inner-Bangkok with over 544 listed companies and combined market capitalization of about THB 8.7 trillion (USD 290 billion) as of 30 May 2011. Due to the large amount of foreign representation, Thailand has for several years been a mainstay of the Southeast Asian economy and a key centre in Asian business. The indices of the stock exchange are SET Index, SET50 Index and SET100 Index. As of Fall 2009, the index is one of Asia's top performing indices, up 58 percent since January.
