Abstract
The evaluation of the short-term effects of the new comprehensive two-child policy will be analyzed in terms of the number of new born populations and the demographic structure. Through the regression analysis of the change trend before the implementation of the new policy, and comparing it with the current population, it is concluded that the implementation of the new policy will promote the growth of the new population. In the same way, compare the changing trends of the population proportions of each age group before and after the reform. The implementation of the new policy has played a certain role in increasing the number of new populations and adjusting the population structure. The analysis of population size and population structure requires prediction of various indicators. Population characteristics such as birth rate and death rate are constantly changing and developing. After the population reaches a certain size, its characteristics will stabilize over time. Therefore, the prediction of population structure (such as gender ratio, urban-rural ratio, age structure, etc.) Queue element method. Analyze the relationship between population size and population structure over time. And based on the predicted data and information, a qualitative analysis of economic development was made.
