中文摘要：

本文研究了银行间风险传染机制，并构建了符合我国银行系统的同业拆借市场网络结构，该网络结构满足应用矩阵法的条件；通过采用矩阵法对银行间风险传染进行测算及仿真，运用最优熵值法构建了上市商业银行的双边敞口矩阵，沿用弗阿菲尼方法估计传染损失率，在此基础上利用C＋＋软件，对具有代表性的五家商业银行进行了银行间同业拆借风险传染测度及仿真研究，根据仿真结果提出各商业银行、损失率、风险爆发、风险传染间的相互关系。

英文摘要：

The risk contagion mechanism and network structure of the interbank lending market which was fit for the banking system in our country was built in this article .After inquiry, the interbank network structure in our country was found to meet the application conditions of matrix method .On this basis, the matrix method was used to measure and simulate the risk contagion in the interbank：the method of optimal entropy was applied to build bilateral exposure matrix , and then the method of loss rate measuring of contagion by Foa Feeney and C ＋＋software was used to measure and sim-ulate the process of risk contagion in banking system after the risk of source bank occurred .According to the simulation results, the relationships among commercial banks , loss rate, risk outbreaking and the risk contagion were obtained .
