摘要
利用人口普查和1%人口抽样调查等数据,对重庆的人口老龄化现状特征进行分析,并利用Preston模型分解老龄化影响因素。研究发现:重庆虽然地处西部,但已成为全国老年人口比例最高的地区;重庆常住人口占全国人口的比例下降,但人口流动规模在不断增加,且省际人口流出数量要大于流入数量;2010年重庆人口平均年龄增加1.163 8岁,高于人口老龄化速度,主要是由于省际人口流出规模较大造成的。
Mainly using the population census and plores the characteristics of aging in Chongqing and the 1% population sampling data, this paper ex- decomposes the influence factors on its regional aging on the base of Preston model. It is found that： although Chongqing is located in the west of China, it has the highest proportion of elderly population; the proportion of the resident population is decli- ning, while the number of the floating population is increasing, and the outflow is more than the in- flow; the aging speed increased by 1. 163 8 years in 2010, and is higher than the ones in a closed soci- ety, which is due to the relatively large scale of outflow population.
