西部地区人口老龄化时空演变及影响因素

Spatio-temporal evolution and influencing factors of population aging in western China

以西部地区为研究区域,运用空间自相关和地理探测器等方法来进行研究。结果表明:省域尺度上,人口老龄化系数逐年递增,各地区人口老龄化存在差异;空间关联上呈现空间自相关,局部空间自相关以高-高、低-低集聚为主。通过研究发现,市域尺度上人口老龄化空间分布特征的主要影响因子是人口自然增长率、职工平均工资。

Take the western region as the research area,and use the methods of spatial autocorrelation and geographic detector to carry out the research.The results show that on the provincial scale,the population aging coefficient is increasing year by year,and there are differences in population aging in different regions;the spatial correlation presents spatial autocorrelation,and local spatial autocorrelation mainly focuses on high-high and low-low clustering.The study found that the main influencing factors of the spatial distribution characteristics of population aging on the municipal scale are the natural growth rate of population and the average wage of employees.
