The Study On The Efficiency Of Commercial Banks Of China And Its Influencing Factors Based On Three-stage DEA Model

Currently, on the one hand the global economy in a difficult period of recovery, the international financial crisis, deep impact far from being eliminated, weak growth in global trade, protectionism. It is predicted that the world economy in the next five years the average growth rate will drop to around 3%. On the other hand Chinese economy into a new normal, greater downward pressure on economic structural contradiction. Harsh external environment, the management of commercial banks to bring severe pressure on commercial banks to carry out the transformation of the business model, change the past, relying solely on the rapid expansion of the balance sheet will be able to bring in huge profits of the traditional business model. In this context, this paper operational efficiency of Chinese commercial banks in-depth analysis of the factors and the efficiency of commercial banks of influence.Firstly, use three-stage DEA method estimate the Chinese Commercial Banks 2009--2014 years efficiency status. The first stage of DEA using traditional methods measure the operational efficiency of commercial banks; stochastic frontier analysis method of the second phase(SFA) analyze the impact of environment variables and random error term investment balance of commercial banks, and on this basis, commercial banks ineffective management and random error term separated from the original input variables adjusted; input variables using the adjusted third stage remeasure operational efficiency of commercial banks.The research results show that:(1) the first phase of DEA, the technical efficiency of city commercial banks is the highest, followed by state-owned banks, joint-stock banks minimum efficiency technology, loss of technical efficiency of commercial banks mainly comes from the pure technical efficiency is not valid.(2) The second stage SFA regression results show that commercial banks deposit the larger cause of investment, the total assets of investment and operating expenses into three larger the redundancy; A + H shares listed on reducing operating expenses input redundancy, improve total assets of commercial banks and deposits utilization.(3) The third stage DEA, the highest technical efficiency of state-owned banks city commercial banks pure technical efficiency highest, followed by silver stock, the lowest state-owned banks; the highest scale efficiency of state-owned banks; the results compared to the first stage, the difference is large, it also shows that the external environment and eliminate random error term is necessary.Secondly, on the basis of commercial banks on banks operating efficiency measure, based on panel data analysis model to explore the innovation, the impact of capital adequacy ratio, non-performing loan ratio, economic growth and market concentration of commercial banks operating efficiency. The results show that the ability to innovate commercial banks impact on its operating efficiency is positive, enhance the innovative capability of commercial banks will help to enhance the efficiency of commercial banks; non-performing loan ratio and GDP growth rate of commercial banks operating efficiency negatively correlated; degree of market concentration and capital adequacy ratio of commercial banks on efficiency was not significant.
