Feature of Ageing Population and Its Economic Impact in China
Abstract：This article takes the aging coefficient and the ratio of the aged and the young as aging targets,calculates and decomposes the regional difference of Chinese aging from 1995 to 2011 using Theil index,examines the factors affecting population aging from the whole country,eastern,central,and western levels using FGLS estimation method and provincial panel data. The results show that: Chinese aging has unbalanced distribution characteristics,and regional differences are significant but not stable in the short term showing repeated fluctuations,but there is growing trend in the long term. After 2004,the provincial aging differences have expanded in the central and the western China,and narrowed in the eastern China,but aging differences among the eastern provinces play the most important role in the total differences. Aging differences within the region are increasing and the differences among regions are descending in the long term,and differences within the region are far bigger than differences among regions,so the total difference is mainly caused by the differences within the region. GDP per capita and birth rate are the most important factors affecting the population aging in China from all levels. Mortality has a negative effect on the aging from the national level,and the rate of city has positive influence in the central and the western China,but the illiteracy rate has no negative effect from all levels.
