摘要: 文章采用剩余预期寿命实际老龄依赖比等动态年龄指标,通过生命表测度老年人口与老龄化,运用空间聚类分析方法,分析 1990 ~ 2010 年中国人口老龄化时空演变特征,并与采用固定年龄方法测算的老龄化结果比较研究表明,动态年龄测算的老龄化程度与老年人口抚养比均趋于下降,空间格局经历北高南低东高西低以重庆市等为中心圈层模式的转变过程;而固定年龄度量的老龄化程度与老年人口抚养比则趋于上升,空间格局主要呈东西分异相比而言,动态年龄指标测度的老龄化更符合人口与社会发展的客观实际,反映老龄化的本质特征,揭示老龄化水平的影响因素及区域差异特征,进而有利于采取更有针对性差异化的策略积极应对老龄化

Abstract: Using dynamic age indexes (remaining life expectancy and real elderly dependency ratio) which measure the rate of population ageing through life table,this paper analyzes the temporal and spatial evolutional characteristics of population ageing in China from 1990 to 2010 with spatial analysis method. The results suggest that the degree of ageing and old-age dependency ratio which measured by fixed age indexes tend to increase,while those measured by dynamic age indexes tend to decrease.The spatial pattern of ageing by fixed age index is mainly differentiated between the east and the west. The ageing pattern by the dynamic age index has experienced the transformation from north high and south lowto east high and west lowand then to the circle pattern centered on Chongqing. The spatial-temporal evolution patterns of ageing based on dynamic age indexes are more likely to reflect the essential characteristics of China??s population ageing and reveal the internal mechanisms of population and social development. Better understanding the influencing factors and the regional differences of ageing patterns enables a more focused differentiation strategies to promote the active response to the
challenges of population ageing.
