内蒙古人口老龄化时空演变及影响因素

The Spatio-Temporal Evolution of Population Aging and Its Influencing Factors in Inner Mongolia

摘要: 利用2000、2010及2020年三期人口普查数据，对内蒙古12个盟市人口老龄化的时空演变趋势进行分析，并从人口、经济、教育维度选取因素探讨影响机制。结果表明：① 内蒙古整体人口老龄化水平低于全国平均水平，但区内差异明显，空间格局由初期形成的“中间高，四周低”逐步向“均质化”方向演变。② 人口老龄化空间分布始终为东北–西南方向，分布重心长期位于锡林郭勒盟苏尼特右旗境内，且整体呈现向东北方向迁移的趋势。③ 影响因素方面，人口自然增率、人均GDP与人均受教育年限与老龄化之间存在显著的关联性。

Abstract: This study analyzes the spatiotemporal evolution trend of population aging across 12 leagues and cities in Inner Mongolia, utilizing data from the 2000, 2010, and 2020 national population censuses. Furthermore, it explores the underlying influencing mechanisms by selecting variables from the dimensions of population, economy, and education. The findings are as follows: The overall population aging level in Inner Mongolia is lower than the national average, yet intra-regional disparities are pronounced. Its spatial pattern has gradually transitioned from the initially formed “high in the central region and low in the peripheral areas” toward homogenization. The spatial distribution of population aging consistently exhibits a northeast-southwest orientation, with its centroid persisting within Sunite Right Banner of Xilingol League over the long term and demonstrating an overall northeastward shifting trend. Regarding influencing factors, the natural population growth rate, per capita GDP, and average years of schooling per capita exhibit significant correlations with population aging.
