城市商业银行多元化战略的影响分析--基于2009-2014年城商行面板数据的实证分析

Analysis on the Influence of Diversification Strategy for City Commercial Banks——Based on Empirical Study of 2009-2014 City Commercial Banks' Panel Data

本文以42家城商行2009-2014年的数据为样本,系统运用统计分析及动态面板GMM估计考察了多元化发展对城商行的影响。研究结果表明,城商行非息收入占比的提升显著降低了盈利增长的波动性,从而在一定程度上分散其经营风险;但是,由于非息收入占比偏低,且以传统低附加值业务为主,加之与净息收入高度正相关,导致其原有的多元化收益被弱化,非息收入的边际增加降低了城商行风险调整后的收益率。因此,城商行应结合自身经营实际情况选择多元化经营模式和程度,积极拓展高附加值的新型中间业务,降低对传统融资业务的依赖。

By using panel data of 42 Chinese city commercial banks from 2009 to 2014, this paper investigates effects of the diversification operation on bank risk and risk-adjusted performance by using statistic analysis and dynamic panel data model with GMM estimation. The results show that the proportion of non-interest income is benefit to reduce city commercial banks＇ profit and income fluctuation. But there is significantly reverse relationship between proportion of non-interest income and city commercial banks risk-adjusted return, due to the low proportion of non-interest income and high correlation of non-interest income and net-interest income. Therefore, it is suggested that city commercial banks should combine with actual situation to choose suitable pattern of diversified operation, at the same time, focus on strengthening newly developing and high value-added intermediary business to broaden source of intermediary business income and optimize income structure.
