Empirical Study On The Impact Of Population Age Structure Change On Economic Growth

The relationship between population age structure change and economic growth is a hot issue in academic research.In recent years,as our country's natural population growth tends to stabilize at low levels,the problem of a shrinking proportion of the working-age population and an aging population has begun to have a negative impact on the sustainable growth of the economy.At present,we need to conduct an in-depth study on the relationship between population age structure changes and economic growth in order to find a solution.Based on the previous studies,this paper attempts to explore and construct a theoretical framework for the changes of the population age structure to influence economic growth through labor supply,human capital,savings rate and public investment.Taking Fujian Province as an example,this study conducts an empirical study of the above relationship.The results show that,firstly,over the past few decades,the large population of working-age population resulting from changes in the age structure of the population in Fujian Province has become an employed population capable of promoting economic growth.However,under the influence of various factors,the unemployment rate in Fujian Province has not kept at a low level since 2000,and the phenomenon of "labor shortage"and "employment difficulty" coexist.This shows that at present,Fujian Province has failed to bring the remaining working-age population Make full use of;Second,the drop in total dependency coefficient in Fujian Province can raise the level of human capital,but the impact is relatively small because there are many obstacles;Thirdly,the total dependency coefficient is negatively correlated with the savings rate of residents in Fujian Province.The increase of the savings rate brought by the decrease of the total dependency coefficient is mainly caused by the rapidly falling children's dependency coefficient.The increase of the elderly dependency coefficient promotes the savings rate of residents rise;The total dependency coefficient is negatively correlated with the economic growth in Fujian Province.The changes in the age structure of the population can promote economic growth but the impact is relatively small,which is mainly caused by the changes in the child support factor.The effect of the elderly dependency coefficient on economic growth is not significant;Fifth,the internal aging phenomenon of working-age population in Fujian Province is becoming more and more serious.The age structure advantage of the population will be gradually lost in the future.How to excavate and expand as much as possible and extend the age structure advantage of the population are the problems to be solved urgently.In this case,this paper puts forward some policy suggestions such as further promoting employment,promoting the improvement of human capital level,perfecting the old-age security system,extending the retirement age and changing the economic growth mode.
