非利息业务与银行效率研究:来自中国银行业的实证证据

Non-interest Business and Banks' Efficiency: The Empirical Evidence from Chinese Banking

本文运用我国117家商业银行2000-2012年的数据,采用两阶段法探讨非利息业务与银行效率的关系。第一阶段采用随机前沿法测量成本效率和利润效率,第二阶段构建回归模型分析非利息业务对银行效率的影响。研究发现:首先,我国商业银行的成本效率普遍高于利润效率;银行效率测量中不考虑非利息业务产出导致银行效率明显低估;成本效率和利润效率近年来均有所提高。其次,非利息业务发展并未提高银行效率,反而显著降低银行效率。最后,本文将非利息业务拆分为佣金手续费业务和交易业务,发现佣金手续费业务为商业银行带来积极效应,而交易业务则带来消极效应。

Using the data of 117 Chinese commercial banks from 2000 and 2012,this paper discusses the relationship between non-interest business and banks' efficiency by the two-stage approach. At the first stage,this paper measures the cost efficiency and profit efficiency by using stochastic frontier approach. At the second stage,this paper establishes a regression model and analyzes the effects of non-interest business on banks' efficiency. The research finds that:firstly,the cost efficiency of Chinese commercial banks is generally higher than profit efficiency;banks' efficiency is measured without considering the clear underestimate of banks' efficiency caused by non-interest business;both cost efficiency and profit efficiency rise in recent years. Secondly,the development of non-interest does not raise banks' efficiency but significantly reduces banks' efficiency. Finally,this paper classifies non-interest business into commission service charge business and trading business and it finds that the commission service charge business brings active effects on commercial banks but the trading business brings passive effects.
