摘要本文梳理了几种重要的动态死亡率预测模型,给出了长寿风险度量的三种方法,选取了保险公司及国家官方公布的人口死亡率数据,度量了保险公司的两类长寿风险,对不同方法下长寿风险的度量结果进行比较,并分析了极限年龄与折现率变动对长寿风险影响的敏感性。研究发现:基于保险公司经营稳健性的视角,第一类长寿风险的度量应采用随机模拟法,第二类长寿风险的度量应采用标准公式法;极限年龄的变动对长寿风险的影响较小,保险公司无上调经验生命表极限年龄的必要;长寿风险对折现率的变动较为敏感,提高折现率,保险公司经营中的长寿风险显著降低。 This paper summarizes the several important dynamic mortality models, proposes three methods of measuring longevity risk, and measures the two kinds of longevity risk of insurer by using the mortality data from insurance companies and National Bureau of Statistics. The study shows that the results of longevity risk are different in these methods. Based on the prudence principle, insurer should select the stochastic simulati6n method to measure the first kind of longevity risk, and select the standard formula method to measure the second kind of longevity risk. Moreover, the longevity risk is not sensitive to the terminal age, but sensitive to the discount rate. The longevity risk will decrease significantly by increasing the discount rate.
