외국자본의 진입과 은행의 생산성 변화- 한국과 인도네시아를 중심으로 -

Abstract

This paper tests the productivity change in Korean and Indonesian Banking Industry after foreign capital entry. Using 36 banks that continue to exist in 2004, we analyzed DEA product efficiency, efficiency gap and change in ranking before and after foreign capital entry. We further established statistical relationship between efficiency and CAMEL variables by employing logit regression analysis. The evidence suggests that foreign acquisitions did not have any significant effect on efficiency. In the case of Korea, domestic acquisitions have significant positive effect on efficiency than foreign acquisitions. In the case of Indonesia, foreign acquisition has insignificant effect on efficiency. Results also indicate that the changes in net interest margin had a positive effect on the change in efficiency between 2000 and 2004. In commercial banks that give more weight on deposits and loans, net interest margin is the key variable of their competitive advantage.
