This thesis aims to study, by means of economic framework, the effects of corporate welfare burden on private investment in Thailand. We focus on mandatory corporate welfare i.e. Social Security Fund, Workmen’s Compensation Fund as well as voluntary corporate welfare i.e. Provident Fund. Furthermore, we use quantitative analysis to analyze the effects of corporate welfare establishment on aggregate private investment and sub-aggregate private investment in Thailand by “Ordinary Least Squares” (OLS) and “Cointegration and Vector Error Correction Model” (VECM). Data is time series from 1977 to 2007. In addition, we analyze effect of corporate welfare contribution burden by using OLS. Time series data from 1992 to 2007 are used in this analysis. The explanatory variables in model are Corporate Welfare Contributions, Gross Domestic Product, Cost of Capital and Real Wage.

Secondly, corporate welfare contributions burden both mandatory corporate welfare and voluntary corporate welfare insignificantly affect on aggregate private investment. Thirdly, mandatory corporate welfare negatively affect on transportation and communication sector.
