      abstract = {This study aimed to find an effective and efficient  direction for future projects through the performance  evaluation of the drainage improvement project. To achieve  the goal, it analyzed the effects on rice production and  welfare after the drainage improvement project was  administered by the Korea Rural Community Corporation (KRC)  by applying the difference in differences (DID) estimation  method and an equilibrium displacement model (EDM).  Primarily, this study focused on subsurface drainage  facilities’ effects on production, which consisted of an  increase in yields and a decrease in the time of operating  agricultural machines. The analysis result showed that the  amount of yields increased by 18.75kg/10a, while machine  operation decreased by 6.61 min./10a after the  implementation of the project. We found that these effects  were reduced when the slope of a field increased or a  drainage grade deteriorated. We also discovered that the  producer surplus increased by 3,129.9 million won due to a  change in the equilibrium of regional rice market affected  by the project for 30 years. We calculated the net benefit  to be 279.9 million won. The net profit increased when  project target areas were selected in consideration of a  drainage class and a slope degree. The level of increase in  net profit was higher when considering the drainage class  than the slope. The results implied that the drainage class  is relatively more significant than the slope among the  criteria for selecting project target areas to improve  project effectiveness.},
