我国商业银行多元化经营与绩效的关系——基于50家商业银行2005—2012年的面板数据分析

The Relationship Between Diversification and Performance of Chinese Commercial Banks:Based on Analysis of Panel Data of 50 Banks During 2005—2012

本文基于收益与风险的视角,运用我国50家商业银行2005—2012年的数据,通过固定效应模型和面板门限模型考察了多元化经营对银行绩效的影响。实证结果表明,多元化经营与银行绩效之间存在非线性关系;大型商业银行实施多元化战略在提高收益的同时分散了风险;小型商业银行的多元化经营提升了盈利能力,但增加了信用风险。在此基础上为现阶段我国商业银行开展多元化经营提出了政策建议。

Based on the perspective of retum and risk, this paper uses panel data of 2005- 2012 Chinese commercial banks to investigate the influence of diversification on perform- ance by building panel threshold model and fixed effect model. Empirical results indicate that there is nonlinear relationship between diversification and bank＇s performance. Diversification of large banks increases revenue and spreads risk while diversification of small banks enhances profitability, but raises credit risk. Policy Recommendations of diversifica- tion are proposed on the basis of specific conditions of Chinese commercial banks at the present stage.
