Later on in 1856, when Thailand entered into the Bowring Treaty with England and into other treaties with other Western countries, economic businesses began. The economic change transformed people’s lifestyles in both urban and rural areas to that of industrial manufacturing for import substitution and eventually for exports. The base of the Thai economy has rapidly changed from agriculture to services and manufacturing. In 1961, when Thailand started the first five-year “National Economic and Social Development Board (NESDB)”, the Thai economy was mainly reliant on the agriculture sector. According to the statistics of the NESDB, the share of agriculture decreased from 40 per cent of gross domestic product (GDP) in 1960 to 10 per cent in 2002, and manufacturing increased from 13 per cent to 37 per cent of GDP. Economic growth has been impressive over more than three decades. From 1987 to 1995, growth averaged about 10 per cent a year. In 1996-1997, an economic crisis drastically hit Thailand's economy.
