A Study On Economic Growth Of The Population Age Structure Change

As a key element of economic development,labor force is the main content of economy research.In the face of China's population aging degree deepening,in 2015,our country implements comprehensive open "two-child" policy,this is one of countries actively cope with the aging of the population action.The change of policy will change the population structure in our country.An increase in the number of newborn and the increase of aging population will affect social upbringing than level,demographic dividend problem once again become the focus of attention.In the process of demographic transition influence on a country's economic growth,total output is not directly impact on society,but by variables affecting economic growth,after a series of economic variables,will eventually cause related economic consequences.In the process of demographic transition age shift as the main characteristics,directing effect of conduction variables mainly include level of employment,household saving and consumption level,the level of social security,industrial structure adjustment,the level of human capital accumulation,etc.Based on the perspective of demographic dividend,the demographic transition mechanism of the influence of the economic growth in our country are analyzed.First of all,based on the study of the scholars at home and abroad,based on the perspective of demographic dividend,in theory,the demographic transition in the process of impact on economic growth mechanism;Secondly,on the measure of demographic dividend,application dependency ratio and the ability to raise than effectively,the demographic dividend for the first time and second time,discussed the demographic dividend of China's demographic dividend changes;Again,combined with the Solow model and the introduction of population structure and quality variables(effective dependency ratio and the dependency ratio),from the change of the number of labor supply and savings(investment)levels and human capital accumulation level these three aspects influence on economic growth for empirical analysis.Finally,from the demographic dividend at the present stage in China,the industrial structure,such as birth policy,proposed the rationalization proposal.This article innovation place:(1)Starting from the definition of demographic dividend,on the measure of demographic dividend,will be the first demographic dividend and the second demographic dividend,from the eastern,central and western comprehensive changes of the demographic dividend in China.(2)Based on the classical theories of economic growth--the solow model,the introduction of demographic variables,and combine the dependency ratios that measure a demographic dividend from the change of the number of labor supply,household savings rate(investment)and human capital accumulation level three aspects to analyze the demographic transition,the impact on the economic growth path.
