中国商业银行利润效率测度研究——基于分位数回归方法

On the Estimation of Profit Efficiency of Commercial Banks in China:Based on Quantile Regression

本文选取2000-2009年中国14家商业银行(4家国有银行和10家股份银行)有关数据,首次运用分位数回归方法对商业银行的利润效率进行测度。测度结果表明,中国商业银行利润效率总体有不断上升的趋势,但整体水平不高,且银行间差别较大。相对于股份制银行,国有银行平均利润效率在2003年存在一个低位转折点,而在2008年存在一个高位转折点,本文对此解释是,在应对金融管理体制改变与西方金融危机冲击过程中,国有银行相对于股份银行体现出更强的适应性与稳健性;这一结果在现有文献中并未得到充分地体现和说明。

This paper estimates the profit efficiency of 14 commercial banks including 4 state-owned banks and 10 joint-stock banks in China from 2000 to 9.009 by quantile regres sion. The results show that the profit efficiency, which is constantly upwards as a whole, is at a relatively low level on average, and differs widely in banks. Compared to the average profit efficiency of joint-stock banks, there are low and high turn points of the average profit efficiency of state-owned banks in 2003 and 2008 respectively. This paper explains that, in the process of the response to financial system reform and western financial crisis, state-owned banks have greater flexibility and robustness than joint-stock banks; this con- clusion is not fully stated and confirmed in current relevant literature.
