摘　　要：针对保险索赔次数数据,本文基于混合Poisson分布研究了保险中集合保单不同质性的度量方法;给出不同质性系数的定义、估计方法及实例。A method of measuring the heterogeneity of policyholders has been studies based on the mixed Poisson distribution which be used prevalently to describe the numbers of claims in insurance. The coefficient of the heterogeneity of policyholders be definited and estimated by the moments mothed. Moreover, some examples have been investigated in this paper.
