DEA-based Empirical Research on the Performance Analysis of China＇s Commercial Bank Information Security System Application

In this paper, the operating performances of the main commercial banks＇ information security management system applications are empirically researched using the DEA method of operating efficiency＇s multi-stage super efficiency. The DEA model of multi-stage super efficiency is established for the commercial bank information security system applications of China＇s banks using data envelopment analysis （DEA）, and then output efficiency, taxation efficiency, and comprehensive efficiency are analyzed by choosing eight banks such as Industrial and Commercial bank of China as sample data, and finally the operating performance of Chinese commercial banks＇ information security management system is concluded.
