摘要
我国已经进入了人口老龄化社会,地区间的人口发展受经济发展、生育控制、文化水平等因素的影响存在明显差异,分析这种差异的程度及趋势,对于我国实现可持续发展、缩小地区间差异具有深远的意义。首先对我国人口老龄化的特点进行分析,然后基于1995—2008年我国31个省市的65岁及以上老年人口比重、老年人口抚养比以及各地区的GDP比重指标进行聚类分析。结果表明,地区经济越发达,人口老龄化问题越严重;经济越不发达,人口老龄化程度相对越低。
China has entered population aging society.The influeces on population development between regions by economic development,birth control and cultural factors are significantly different.An analysis of the extent and trend of the difference is far-reaching significant for China to achieve sustainable development and narrow the differences between regions.Firstly,it analyzes the characteristics of China＇s aging population.Then,it makes a cluster analysis based on 1995-2008,China＇s 31 provinces and over 65 years the proportion of elderly population,the elderly dependency ratio as well as indicators of regional GDP.At last,the results shows that the more developed regional economy,the more serious problem of an aging population;economy is more underdeveloped,the degree of population aging is relatively lower.
