Spatial Analysis of the Aging Population and Socio-economic Factors of China: Global and Local Perspectives

Abstract

Population aging has become an inevitable trend and exerted profound influences on socio-economic development in China. In this study, we utilized data from national population census and statistical yearbooks in 2010 and 2020 to explore spatio-temporal patterns of aging population and its coupling correlations with socio-economic factors from both global and local perspectives. The results from Local Indicators of Spatial Association (LISA) uncover notable spatial disparities in aging population rates, with higher rates concentrated in the eastern regions and lower rates in the western areas of the Chinese mainland. The results from the global correlation analysis with the changes in aging population rates show significant positive correlations with government interventions and industrial structures, but negatively correlated with economic development, social consumption, and medical facilities. From a local perspective, a Geographically Weighted (GW) correlation analysis is employed to uncover local correlations between aging trends and socio-economic factors. The insights gained from this technique not only underscore the complexity and diversity of economic implications stemming from population aging, but also provide invaluable guidance for crafting region-specific economic policies tailored to various stages of population aging.
