中国县(区)人口长寿水平的影响因素分析

根据现有研究文献 ,本文重点检验区域环境和社会经济两大类非个体因素是否对区域人口长寿水平有直接的影响 ,以便确定不同区域人口长寿水平的影响因素。多元线性回归的分析结果表明 ,在所有社会经济与环境因素中 ,老年人居住地的气温、气候、经度、土壤类型以及粮食作物类型等是影响区域人口长寿水平的主导因素 ;而婴儿死亡率和粗死亡率同样影响着区域的人口长寿水平 ,但其影响强度不如上述环境因素。

Analysis of Determinants of Population Longevity at County Level in China

Based on existing literature, this paper is mainly intended to test whether environmental factors and socio-economic factors will have direct effects on the longevity at county level in China, in order to identify the major determinants of local longevity level. Results from multi-variate linear regression show that such socio-economic and environmental factors as temperature,climate,logitude,type of soils,as well as type of grain crop play a major role in shaping the longevity at county level,and that infant mortality and crude death rate also have some direct impact on longevity,but the impact is not as strong as that of the environmental factors mentioned above.
