中国人口健康分布的时空变化与影响因素
发布时间：2018-09-07 14:19
【摘要】：该文利用最近3次人口普查获得的资料,对我国省级层面的人口健康分布的时空变化特征与影响因素进行分析。结果表明:1)近20年我国居民总体的健康状况得到较大改善,但人均预期寿命存在明显的省际差异,呈现西部较低、中部次之、东部最高的空间梯度特征,差异程度随时间不断降低;2)各地区健康分布并非表现出完全的随机性,而是在总体上呈现出一定的空间集聚趋势,但集聚趋势随时间变化有所弱化;3)地区人均预期寿命的增加速度与初始水平负相关,初始水平较低的地区增速普遍高于初始水平较高的省区,空间收敛趋势明显;4)人均GDP、食物支出占比、森林覆盖率与废水处理达标率等指标较高的地区的预期寿命相对较高,城市化的快速推进与医疗设施禀赋变化对人口健康的净效应总体为负。
[Abstract]:Based on the data obtained from the last three censuses, this paper analyzes the temporal and spatial changes of population health distribution at the provincial level in China and its influencing factors. The results show that the overall health status of Chinese residents has been greatly improved in the past 20 years, but the life expectancy per capita is obviously different between provinces, showing the characteristics of spatial gradient in the west, followed by the middle, and the highest in the east. The degree of difference decreases with time. (2) the health distribution of each region is not completely random, but shows a certain trend of spatial agglomeration in general. However, the trend of agglomeration weakens with time. (3) the increase rate of life expectancy is negatively correlated with the initial level, and the growth rate of the region with lower initial level is generally higher than that of the province with higher initial level. The spatial convergence trend is obvious (4) the proportion of food expenditure per capita GDP, is higher, and the life expectancy is relatively high in areas with higher forest coverage and wastewater treatment. The net effect of the rapid development of urbanization and the change of medical facilities on population health is negative.
