基于改进DEA方法的我国银行业效率实证研究

本文采用改进的DEA方法和相关模型，利用最近3年的样本数据，测度了我国银行业最新的技术效率、超效率、投入冗余率和产出不足率。实证结果显示：国有银行与股份制银行的技术效率差距明显缩小；国有银行的超效率的排名的波动性比股份制银行小；利息支出与收入差距并不是影响银行效率的主要原因；为提高我国银行业的效率，国有银行应通过缩减员工人数和固定资产投入规模来降低投入冗余率，股份制银行应通过积极发展中间业务来降低利润不足率。

Empirical Study on the Efficiency of China's Banking by the Reformative DEA Method

This paper,using the reformative DEA method and model,analyzes the technical efficiency,super- efficiency,input redundancy and output deficiency of China's banking based on data of the recent 3 years.Empirical results indicate that the gap of the technical efficiency between the state-owned commercial banks and the stock commercial banks has shortened obviously.And the former one is much more steady than the latter on the placement of the super-efficiency.The income and expend of interests are not the main ...
