金融脱媒对商业银行利润效率影响的实证研究

摘要

This paper measures the profit efficiency of 30 commercial banks in China from 2008 to 2014 and studies the impact of financial disintermediation on the profit efficiency by single-stage stochastic frontier analysis .It is found that during the given period ,the re-intermediation effect eliminates the impact of asset disintermediation on the profit efficiency of commercial banks ,and improves the profit efficiency of commercial banks .However ,the re-intermediation effect fails to eliminate the impact of liability disintermediation on the profit efficiency of commercial banks ,liability disintermediation still lowers the profit efficiency of commercial banks .It is also found that the profit efficiency of the five major state-owned commercial banks is the highest ,the profit efficiency of city commercial banks is better than that of joint-stock commercial banks ,and the profit efficiency of foreign commercial banks is the lowest .%采用单阶段随机前沿分析方法 ,测算2008-2014年30家商业银行的利润效率 ,并分析金融脱媒对利润效率的影响.研究发现在样本期间内 ,脱媒校正效应不但消除了资产方脱媒对商业银行利润效率的冲击 ,而且提高了商业银行的利润效率 ,然而脱媒校正效应并没有完全消除负债方脱媒会对商业银行利润效率的冲击 ,仍然表现为负债脱媒降低商业银行的利润效率.另外还发现 ,五大行的利润效率最高 ,城市银行的利润效率高于股份制银行 ,外资银行的利润效率最低.
