中国人口老龄化省内差异的变化:2000-2010——基于“五普”“六普”分县资料的分析

The Change of Differences within Province of Population Aging in China:2000-2010—— Analysis Based on the County-Level Population Data of the Fifth and Sixth Census

地区发展不平衡是中国人口老龄化的显著特征之一。以第五次、第六次人口普查数据为基础,分析了2000-2010年我国人口老龄化的省内差异变化情况。结果显示,人口老龄化程度的省内差异总体上呈扩大趋势,约有三分之二省份的人口老龄化程度省内差异在扩大。省内差异对人口老龄化总体差异的贡献大于省际差异,且2000-2010年其贡献率呈上升之势,但省际差异的缩小仍然导致了这一期间总差异的缩小。

Unbalanced regional development is one of the prominent features of population aging in China. Based on the fifth and sixth census data, this paper analyzes differences of population aging within province in China during 2000-2010. Results show that the differences of population aging within province expanded in generally and the differences of about two-thirds provinces had expanded in this period. The contribution of differences within province to the total difference in China is more than that of inter provincial difference, and contribution rate of differences within province increased during 2000-2010, but the total difference of population aging in China had decreased because inter provincial differences turned smaller in this period.
