This study uses DEA (Data Envelopment Analysis) to calculate the comparative efficiency of SOC (Social Overhead Capital) improvement program in regional development policy. Generally, regional development policy is charged of a large proportion of supply on public investment capitals. Data envelopment analysis is widely used to evaluate how efficiently regional development policy supply the social overhead capital for the regional economics. In this study, the efficiency of social overhead capital is calculated by the linear function of input and output factors. Especially, this study used time series data for input factors from annual reports of social overhead capital.In this study, the existing mathematical analysis methods which are DEA (Data Envelopment Analysis), PFP (Partial Factor Productivity), TFP (Total Factor Productivity), are reviewed and DEA is selected to calculate the efficiency for SOC. Among the regional social overhead capital, trade ports are selected and reviewed for regional development policy, because trade ports are major factor on the SOC of regional development policy. Also, an analysis of slack variables is accomplished as a one of linear program method. The results of this study suggested the input and output factors of slack variable needs to be adjusted to the efficiency between regional development policy and suggested to the investment program for social overhead capital.
