Abstract: The regional perspective of“getting old before getting rich”in China is framed by the comparison in population ageing between less developed and more developed areas. Basing on the connotation of this phenomenon，this paper constructs measurement indexes to describe the phenomenon quantitatively and analyzes the severity，trends and causes of this phenomenon in China. The results show that，while trends in population aging in different regions across China are broadly consistent with regional levels of economic development，spatial patterns of ageing have been changing. The inter-regional trend of“getting old before getting rich”has become increasingly severe. The reasons why the phenomenon becomes increasingly serious are the dramatic growth in migrant population，which is highly age selective and concentrated in the developed regions.

Keywords: Getting Old Before Getting Rich, Regional Difference, Spatial Distribution of Population Ageing, Migration

摘要： 地区间“未富先老”现象，即经济欠发达地区人口老龄化程度相对于经济发达地区超前于经济发展水平。文章从此内涵出发，构造了地区间“未富先老”现象的测度指标，并量化描述了我国地区间“未富先老”现象; 在此基础上，文章重点考察了此现象在我国的严重程度、发展趋势以及形成原因。结果显示: 我国“各地区老龄化程度与经济发展水平具有一致性，自西向东呈阶梯上升”的人口老龄化空间分布格局已经发生本质改变; 上世纪90 年代以来，我国地区间“未富先老”现象的严重程度由“不严重”变为“严重”，并有向“极其严重”变化的趋势; 流动人口数量剧增、年龄选择性以及大量向发达地区集中是我国地区间“未富先老”现象日趋严重的原因。
