银行成本无效率的实证研究——中国主要商业银行及其引进的战略投资者

Empirical Study of Cost Inefficiency for Banks——Chinese Major Commercial Banks & Their Strategic Investors

引进战略投资者是中国银行业应对全面对外开放的重要拳措。本文基于随机边界成本函数首次实证研究了中国主要商业银行及其战略投资者的成本无效率水平。实证结果发现，虽然在中国主要商业银行和战略投资者的成本无效率之间并没有一条截然的分界线，但是战略投资者的成本管理水平普遍较高，有前者学习和借鉴的空间；从成本无效率变化的趋势看，中国国有和股份制商业银行的管理水平在逐年改善，与战略投资者的成本效率有收敛的趋势。

In order to adapt to complete opening to the outside world, China banking begin to introduce some strategic investors. The paper based on stochastic frontier function firstly makes an in - depth empirical study about cost inefficiency of China major commercial banks and their strategic investors. The study finds that although not all the latter＇s cost inefficiency is worse than the former, the former should learn the advanced experience of controlling cost from the latter. In the period of the observation, state - owned banks and stock - holding banks constantly improve their inefficiency, From the tendency of its change, the sample hanks＇efficiency will be convergent.
