Study On Efficiency Of China’s Listed Commercial Banks And Influence Factors Based On Three-stage Super DEA Model

Commercial Banks in China faces a major competitive and rapid change environment, to improve the efficiency of traditional commercial Banks is the most important part of the commercial bank management. Based on the listed commercial Banks in China, we can easily analyze the internal operating process in order to divide the bank’s overall business process into three interrelated sub-processes: the capital organization, capital allocation and capital profit, using the three-stage super DEA model to measure the efficiency of the three sub-processes, including technical efficiency, pure technical efficiency, scale efficiency from 2008-2013.based on the measured results to analyze the inefficiency produced in which stage, at the same time compare the difference of three-stage efficiency between the state-owned Banks, joint-stock Banks, city commercial Banks. then set up the econometric model, use the regression methods to analysis the possible factors that influence efficiency of commercial Banks. Here we choose the main influence factors: return on equity, non-interest income accounted, non-performing loan ratio, market share ratio, capital adequacy ratio, the first big shareholder’s shareholding, make these factors as independent variables, the banking efficiency value as the dependent variable to do multiple regression analysis.The study result shows : ① Most commercial Banks in china’s overall technical efficiency are not effective, only two Banks are in the effective frontier during the inspection period; ② During the inspection period, the technical efficiency of commercial Banks in China have a certain degree of increase, the overall technical efficiency mainly comes from pure technical efficiency rather than the scale efficiency; ③In general, the shareholding commercial Banks’ overall efficiency is the highest, state-owned commercial Banks take the second place, the city commercial Banks works worst; ④ In terms of the efficiency of the three-sub stages, the capital organization stage is low,profit and capital allocation stage is relatively high, the efficiency of different stages is also different in each sample banks; ⑤ The multiple regression results show that the non-performing loan ratio, capital adequacy and market share ratio has significant effects on the efficiency of listed commercial Banks, and return on equity, non-interest income ratio, the first big shareholder’ shareholding are not significant.Based on the above empirical results and analysis, and finally put forward the specific measures to improve the efficiency of Chinese commercial Banks: ①to further promote transformation and upgrading of the traditional commercial bank; ①②adopt the asset-light strategy to develop the business; ③strengthen the capital complement, keep the asset scale grow in a reasonable way; ④ optimize equity structure, effectively promote capital flow; ⑤ strengthen the construction of information, using the power with technology rather scale power.
