Abstract: This article proposes and proves a proportional relationship between the increment of average life expectancy and the number of people who are still alive in the corresponding life table, gives the method of establishing complete life tables of each year of China's provincial regions during the research period by proposition compilation, describes the steps of predicting the peak period of aging population based on compiled life tables, and constructs a fitting sample with a high accuracy and the predictive value of aging people consistent with the Vector Autoregression Model method. Finally, this article conducts an empirical analysis by taking Shanghai as the example and the results show that it helps increase the overall number of people and aging people and the accuracy of the middle and long term predictive value of aging coefficient through modeling and prediction by using the method introduced in this article.
