The trend of population aging in China has become increasingly obvious, but there are differences in terms of the process and characteristics of aging in different regions. Under the background of the coordinated development of Beijing-Tianjin-Hebei region, the population structure panel data of Beijing, Tianjin and Hebei was selected in this paper.Firstly, GM (1,1) model was used to predict the population aging trend in the next decade. The data showed that the aging speed of Hebei Province is significantly higher than that of Beijing and Tianjin.Secondly, the population age structure, dependency ratio, and disposable income were compared and analyzed on a yearly basis, respectively.Finally, it puts forward some suggestions on the response to aging and the development of aging industry in Hebei Province.
