其他摘要：In recent years, due to the increasing proportion of the elderly population in China, the problem of aging has become the hot issue of our country. From the point of view of the absolute aging and relative aging, this paper measures the extent and the speed of population aging of our country, and introduces the Theil index to analyze the difference in the aging of eastern, middle and western of China. The results show that: the degree of aging in western regions is significantly higher than that in the middle and western regions, while the speed of the eastern region is relatively slow. From the decomposition results, overall aging difference comes from the region interior.
