【摘要】：以高龄化系数为测度指标,运用2000年和2010年全国人口普查数据,分析中国大陆31个省(市、自治区)人口高龄化时空分异特征,并利用空间回归模型对影响因素进行解释。结果表明:1)21世纪以来中国人口高龄化日益突出,且高龄化存在显著的空间非均衡特征,10年间总体呈现"北扩西进"的演化特征。2)人口高龄化空间格局并未突破"胡焕庸线",与其存在一致性;从空间关联特征看,人口高龄化呈现正的空间自相关性,集聚特征日益显著。3)除新疆外,其他区域高龄人口增速均快于老龄化,高龄化增速表现出"东-中-西"空间梯度差异。4)人口高龄化是自然地理环境、区域经济发展水平、人口年龄结构等多因素综合作用的结果。
[Abstract]:With the aging coefficient as measure index, using the 2000 and 2010 national census data analysis, China, 31 provinces (municipalities, autonomous regions) difference of population aging time, the influence factors of the interpretation and use of spatial regression models. The results show that: 1) in twenty-first Century to Chinese population aging has become increasingly prominent, and the elderly there is significant spatial non equilibrium characteristics, 10 years showed the evolution of.2 North westward expansion ") aging population spatial pattern did not break through the" Hu Huanyong line ", and there is consistency; from the spatial correlation characteristics, population aging has positive spatial autocorrelation, agglomeration characteristics of increasingly significant.3) in Xinjiang in other areas, the elderly population growth rate is faster than the growth rate of aging, aging showed the" East - West "spatial gradient difference.4) population aging is a natural geographical environment, the economic development level of the region, the population age. The result of the synthesis of many factors.

【正文快照】： 0引言人口老龄化已成为当今世界关注的热点问题。21世纪以来,在人口老龄化的同时,人口高龄化开始显现。人口高龄化是人口老龄化的一种“质变”,是由高龄人口数量的直接增加而形成的绝对老龄化与质量老龄化现象[1],一般指一个国家或地区在一定时期内高龄人口(≥80岁)占老年人口
