摘　　要：在修正确定等价风险度量方式的基础上,应用Copula连接函数,将组合投资各风险之间的相关性考虑在保费定价和风险度量中,提出一种基于Copula函数以及单个风险是混合分布时基于Copula函数的风险度量和保费定价模式,并证明了其满足的性质.On the basis of using Copula function to insurance premium principles and risk measure theory with considering dependence of portfolio investment risks based on modified certainty equivalent risk measure, a Copula based, particularly when detailed mixed distributions are given in individual risks, modified premium principles and certainty equivalent risk measure approach was proposed. Properties of the proposed approach were proved, and the effection was demonstrated by simulated data.
