An Empirical Study On The Impact Of China’s Life Expectancy On Economic Growth

The "14th Five-Year Plan" proposes to increase the average life expectancy by another year,and once again officially include the average life expectancy as an indicator for measuring the national people’s livelihood.It can be seen that it is very important to study the impact of life expectancy on China’s economic development.Scholars at home and abroad have not reached a unified conclusion on the research on the relationship between life expectancy and economic growth,and the existing studies have used the macro data of world economies to verify whether the global average life expectancy has a corresponding impact on economic growth.There is currently no research specifically focused on China,and economic development varies from region to region.Can life expectancy affect China’s economic growth?How does it work under different regional economic conditions?How can the impact of life expectancy on economic growth be better utilized to realize China’s transition to a new economy?These questions prompted us to study the impact of China’s average life expectancy on economic growth.Based on the above situation,this paper uses national time series data and provincial panel data to deeply examine the effect of my country’s per capita life expectancy on economic growth,which has positive significance for improving my country’s high-quality economic development.The purpose of this paper is to study the impact of my country’s average life expectancy on economic growth.To this end,firstly,the relevant literatures at home and abroad are sorted out;then,the per capita life expectancy in my country is described;finally,an empirical analysis is carried out.In the empirical analysis,firstly,the autoregressive distribution lag model is used to study the long-term and short-term effects of the national average life expectancy on economic growth by using 42 years of national time series data from 1978 to 2019.Then,using the provincial panel data from 1980 to 2020,by constructing a fixed-effect model,we examine the impact of average life expectancy on regional economic growth,and corroborate the results of the previous research.Finally,using provincial panel data to construct a threshold model,the focus is to find out whether there is a sudden change in the impact of regional per capita life expectancy on economic growth in my country,and to provide ideas for predicting the impact of the extension of national per capita life expectancy on economic growth in the future.The results of this paper show that:（1）The growth level of my country’s average life expectancy is increasing year by year,and the distribution of average life expectancy and per capita GDP is generally decreasing from east to west.（2）The prolongation of life expectancy per capita promotes economic growth in both the short and long term,and the prolongation of life expectancy and economic growth promote each other.There is a threshold effect on the promotion effect of per capita life expectancy on economic development,and the effect of per capita life expectancy on economic growth will weaken after the threshold value of 75.69 years old.（3）Different genders have different effects on the effect of average life expectancy on economic growth.The improvement of men’s average life expectancy has always had a greater effect on economic growth than the increase in women’s average life expectancy.
