The purpose of this paper is to examine the following two things: First, by using DEA(Data Envelope Analysis) method. we measure the productive efficiency of 26 Korea banks for 7 years(1993-1999) to examine the effects of bank M&A on efficiency, management and profitability index. Second. we compare the change of management index before and after bank M&A. Main results of this study are as follows: First, efficiencies of banks which merged insolvent banks are up except the Housing Bank. Efficiencies of actual M&4 banks are up except the Hanil Bank. For the sold banks, efficiency of Jeil Bank is down. However, that of Seoul Bank is up. Second. changed ratio of liquidity is up, but most of changed ratio of BIS and Fixed Asset are down. Third. 60%-70 % of banks are up in terms of ROA, and ROE.
