EFFICIENCY EVALUATION OF MAJOR BANKS BASED ON DEA-MALMQUIST INDEXES

In this paper, we conducted an in-depth evaluation study on the efficiency of major banks in China using the DEA-Malmquist index method. By collecting, organizing and analyzing the data of major banks, we constructed the DEA model and used the Malmquist index to monitor the efficiency changes of each bank dynamically. The results of the study show that there are significant differences in the efficiency of different banks, and at the same time, with the passage of time, the efficiency of each bank shows different trends of change. The findings of this paper are of great guiding significance for understanding the efficiency situation of China's banking industry, optimizing the allocation of bank resources, and improving the competitiveness of banks.
