论平均预期寿命与平均死亡年龄

首先回顾了平均预期寿命和平均死亡年龄的定义,并总结了当前文献中提到的两者的区别,就其中存在的问题提出了质疑,并以中国人寿保险业经验生命表和中国企业生命表为例,验证了平均预期寿命与平均死亡年龄在数值上是一样的,并在理论上做了证明.结论是两者并不是"有本质区别的"并且两者都会受到死亡年龄结构的影响,同时得到了,平均剩余寿命加上年龄区间的下限值就等于该年龄人口的平均死亡年龄.

Average Life Expectancy and Average Death Age

This paper reviews the definition of average life expectancy and average death age and summarizes the different of the problems in current literature,and put forward the error of them.We proved that the average life table and average death age is the same with the example of China insurance industry experience life table and Chinese enterprise life table, and with theoretical proof.Conclusion is that both of them is not "essential difference" and they all influenced by structure of death age,at the same time,we draw a conclusion that mean residual lifetime add the lower limit of age interval is equal to average death age of the population.
