Abstract: Life expectancy is a comprehensive measurement of mortality,which essentially has a close and interactive relationship with mortality by age.The decomposition of life expectancy difference is a useful tool to study the regular pattern in changes of death mode.Pollard and Arriaga proposed two decomposition methods to explain life expectancy differences.This paper will introduce these two methods and apply them to China’s Life Table of 1990 and 2008.In addition,we compare the characteristics of the two decomposition methods,and provide recommendations for their applications.

摘要: 平均预期寿命本质上与分年龄死亡率存在着密切和交互的关系,将两张生命表上平均预期寿命的差异分解为其分年龄(组)死亡率的差异,可以深入探究死亡水平和模式变化发展的规律。Pollard(1982)和Arriaga(1984)分别提出过分解平均预期寿命差异的方法,两种方法分析的角度和适用性各有不同。文章在此进行介绍和应用;并利用世界卫生组织公布的中国1990年和2008年分性别生命表数据分解其平均预期寿命变化的差异;得出中国近20年来各年龄死亡率下降对平均预期寿命增长的贡献和死亡率变化的规律。最后结合实证分析结果,对两种分解方法的不同特点进行了比较研究。
