Industrial development in Rayong province as well as the foundation of Map Ta Put Industrial Estate play an important role on the Thai economy and account for Thailand's economic growth. Besides, these improvements bring about both positive and negative impact on their community. On one side, such an improvement induces the income source, direct and indirect income, of the community resulting in their better living standard. On the other side, there are also costs of industrial development including environmental, natural resource, and other social problems. However, there is no previous study that can determine the net benefit for the society; therefore, it is important to analyze the advantages and disadvantages of industrial development on their community as a whole. This study focuses on the impact of the Industrial Estate development on Rayong and its surrounding community, the distribution of benefits arisen from the Industrial Estate, and the analysis of overestimated Rayong's GPP. All of these investigations can imply real welfare the community receives. Moreover, this study estimates the community's dependency rate on the Industrial estate, which can imply the level of increased social costs caused by the industrial development that people in the community are willing to pay. In doing so, this study purposes to estimate the committed level of household expenditure, using Linear Expenditure System (LES) The empirical results indicate that the emergence of Map Ta Put Industrial Estate both positively and negatively affects the community. Their people receive both direct revenue from wages and indirect revenue from rental and grocery sales to labors living in this area. Nevertheless, the community has to deal with costs of industrial development. Moreover, the community cannot draw the whole benefit from the Industrial Estate because some benefit was distributed to people outside in forms of capital and labor returns. However, the level of the community's dependency to the Industrial Estate is high. Revenue contributed by the Industrial Estate is still more than the committed level of expenditure, resulting in the net benefit of the society that relieves the anxiety on problems and losses, such as environmental and social problems, accelerated by the Industrial Estate development.
