中国商业银行效率DEA方法的实证分析

An analysis on the efficiency of Chinese commercial banks based on DEA model

为揭示中国13家商业银行的发展状况,采用DEA方法测算出各家商业银行的技术效率、纯技术效率和规模效率,结果表明:2008-2012年,中国商业银行的总体效率表现出稳步上升的态势,而且技术效率的提高主要是来源于规模效率的提高;五大国有商业银行的技术效率、纯技术效率和规模效率都要低于股份制商业银行水平;国有商业银行和股份制商业银行的效率变化趋势基本与中国商业银行的总体效率变化趋势一致.

In order to reveal the development of commercial banks, this paper uses the DEA model to estimate the technical efficiency, pure technical efficiency and scale efficiency of Chinese commercial banks in 2008-2012. The results show that the overall efficiency of Chinese commercial banks shows a steady upward trend, and the improvement of technical efficiency is mainly derived from scale efficiency; In addition, five state-owned commercial banks, technical efficiency, pure technical efficiency and scale efficiency are lower than the level of joint-stock commercial banks; the trend of the efficiency of state-owned commercial banks and joint-stock commercial banks remains the same with the trend of the overall efficiency of Chinese commercial banks.
