Research Into The Impact Of Population Aging On The Export Trade

China is facing an irreversible trend of population aging which will be an unchangeable new normal circumstance and it can’t be changed in a short time.Population aging affects all aspects of China’s economic development.Some scholars believe that population aging leads to changes in the demographic structure,reduction of age-appropriate labor supply is not conductive to the export of capital-intensive product;others believe that population aging will change the comparative advantage of capital-intensive product exports.Therefore,there is no clear certainty and realism on how population aging contributes to the export of capital-intensive products,so it is very necessary to carry out further meticulous and in-depth research and exploration.Capital exploration and research,and use pane regression analysis to reach feasible conclusions.To study this problem in depth,this paper takes the impact of population aging on the export of capital-intensive products as the research theme.The basis of sorting out and summarizing the academic achievements of scholars both domestic and abroad,this paper deeply analyzed the characteristics and development laws of population aging and capital-intensive products,and summarizes population aging.The existing problems are analyzed and the mechanism of population aging affects and export of capital-intensive products,and put forward the research hypothesis that population aging affects the export of capital-intensive products.In view of the research hypothesis,data from 31 provinces and cities in Chinese mainland from 2001 to 2020 are collected,and build the economic measurement model regression and draws the regression conclusion on the basis of controlling the province and time:the population aging has significant regional and degree heterogeneity characteristics and negatively affects the export of capitalintensive products.Research and development investment has a positive intermediary effect on the population aging and the export of capital-intensive products.The intersection of population aging and total capital also has positive moderation effect.Based on these conclusions,this study believes China should further adjust its population policy to increase the supply of labor.While acceleration the economic development of the central and western regions,it is not necessary to excessively pursue the export of capital-intensive products such as high-precision,but should reasonably arrange spatial structure of capital-intensive industries in combination with the advantages of local resources and improve research.Improve the proportion of R&D investment and R&D transformation efficiency to accelerate technological substitution.While popularizing higher education,we will actively promote special education such as skill training and vocational training,so as to lay a talent foundation for the realization of technical substitution:improve the efficiency of labor production by strengthening the deepening of capital to achieve capital substitution.The innovation of this paper is to subdivide the research objectives and study the mediation and moderation effect of R&D investment and total capital.The joint effect is explored and studied and the panel regression analysis is used to draw feasible conclusions.
