摘要 在多生命状态各个体余寿相依的情形下,通过比较边际分布或相依结构,研究终身年金趸缴保费精算现值的差异.采用Copula函数作为相依结构的表示,分别研究:(1)假设各投保集团个体余寿之间相依结构相同的情形下,根据余寿向量在随机序意义下的大小,比较各投保集团终身年金趸缴保费精算现值的大小;(2)假设两个投保集团个体余寿有相同的分布,但个体余寿之间相依结构不相同的情形下,比较其终身年金趸缴保费精算现值的差异. The paper mainly focuses on the present value of single premium life annuity based on the multi-life status.Considering the dependence structure of policy holders' surplus life,the present values of life annuity using the Copula function and stochastic order are compared.Two different cases are discussed:(1)suppose that the surplus life of multi-life statues has the same dependent structure and the different marginals distributions;(2)suppose that the surplus life of multi-life statues has the different dependent structure and the same marginals distributions.
