摘　　要：利率市场化将定价权逐渐转移至市场主体,其直接后果是银行间竞争加剧,存贷利差收窄。本文基于2000-2012年我国50家商业银行的面板数据,引入存贷利差和时间哑变量度量利率市场化,运用固定效应模型搭配Driscoll-Kraay稳健标准差分类检验利率市场化背景下不同类型银行竞争度与风险关系的差异性,结果表明:不同类型银行的Lerner指数、净利差的走势具有明显差异;大型银行受"风险转移效应"主导,竞争有助于提高其稳定性,中小型银行受"利润边际效应"主导,竞争加剧时倾向于追求高风险项目以弥补利润损失。因此,在利率市场化改革实施过程中,需对不同类型的商业银行实施差异化管理,对中小银行进行重点引导。The interest rate marketization will gradually transfer pricing to the mainbody of the market,whose direct consequence is the rising of competition between banks,narrowing savings and loan spreads. Based on the panel data of Chinese 50 commercial banks during 2000- 2012,the paper introduces deposit and loan spreads and time dummy variable to measure the interest rate marketization,and uses fixed effects model with Driscoll- Kraay robust standard to empirically examine the differences between the different types of bank competition and risk relationship under the background of interest rate marketization. Research shows Lerner index and net interest margins of different type of banks has obvious difference; led by risk transfer effect＂,competition will help large banks improve the stability,led by ＂ marginal profit＂,small and medium- sized banks tend to pursue high risk projects in order to make up for the loss of profits when competition is rising. Therefore,in the process of implementing market- oriented interest rate reform,we need to implement different management for the different types of commercial banks and guide small and medium- sized banks.
