摘　　要：目的:估计2000—2020年中国省级地区预期寿命差距及趋势,分析这一差距的主要社会经济影响因素。方法:基于log-quadratic模型估计预期寿命,采用主成分分析法和回归分析法解释其影响因素。结果:2000—2020年省级地区间出生预期寿命差距明显减小,但老年人口呈扩大趋势。社会经济地位、危险因素和卫生服务因素对预期寿命差距的解释度分别为71%、60%和43%,三者共同的解释度为74%。结论和建议:当前省级地区间预期寿命差距明显,差距可以通过以上三个因素解释。但健康生活方式的中介效应没有预期显著,地区之间健康差距在一定程度上还受到文化等因素影响。建议:一是对健康生活方式等进行有效干预,二是重点关注文化和卫生服务因素等的影响。Objective:To estimate the life expectancy gap and trends in China s provincial regions from 2000 to 2020,and to examine the socioeconomic factors contributing to the life expectancy gaps.Methods:The log-quadratic model was used to estimate life expectancy,and influencing factors were analyzed based on principal components analysis and regression analysis.Results:The findings of the study indicate a significant reduction in the gap of life expectancy at birth among China s provincial regions from 2000 to 2020.However,the gap in life expectancy for the elderly population is widening.Socioeconomic status factors,risk factors,and health service factors account for 71%,60%,and 43%of the gap in life expectancy among provinces,respectively,collectively explaining 74%.Conclusions and Suggestions:The current life expectancy gap between provincial regions in China remains substantial,determined by socioeconomic status factors,risk factors,and health service factors.However,it is worth noting that the impact of a healthy lifestyle as a mediating factor is not as significant as anticipated,suggesting that cultural and environmental factors also play a role in the regional health gap.It is recommended that,effective interventions such as healthy lifestyles should be implemented,and secondly,focus on the impact of cultural and health service factors.
