综合经营有助于提升商业银行绩效吗——国际经验与我国实证

Can Comprehensive Operation Improve the Performance of Commercial Banks?——International Experience and Empirical Evidence in China

本文首先研究了全能银行和金融控股公司两种综合经营模式的国际经验,然后在CAMEL评级体系的框架下,采用调整后的赫芬达尔指数和熵指数度量综合经营程度,运用我国50家商业银行2005-2012年的数据,分析综合经营对银行绩效的影响。实证结果表明,整体而言,综合经营有利于银行管理水平和盈利能力的提高,但不利于资本充足率、资产质量和流动性的提升;上市商业银行综合经营的正效用较为明显而非上市商业银行综合经营对绩效产生了严重的负面影响。

This paper first studies the international experience of two comprehensive operation modes including universal banking and financial holding company,and then,based on CAMEL Rating System,we analyze the influence of comprehensive operation on the performance of commercial banks by using adjusted Herfindahl index and Entropy index to measure comprehensive operation extent and using the data of 50 Chinese commercial banks from 2005 to 2012. Empirical results indicate that comprehensive operation is beneficial for the overall banking industry to improve its management ability and profitability. However,it is disadvantageous in enhancing capital adequacy,asset quality and liquidity; The positive utility of the comprehensive operation of listed commercial banks is relatively obvious but the comprehensive operation of non-listed commercial banks has a serious negative effect on the performance.
