The Driving Effect Of Human Capital Flow On Regional Economic Growth ——Analysis Based On The Uzawa-Lucas Two-Sector Model

The sixth plenary session of the 19 points out that the elements of the current our country economy development condition,combination and allocative efficiency has many changes,facing the hard constraint of obvious increase,environmental constraints,close to the limit,high quality development and innovation of science and technology become a constraint to ensure economic growth under the condition of the necessary path "optimal solution".The investment and accumulation of human capital is the key to ensure the long-term stability of scientific and technological innovation ability to promote economic growth.Endogenous economic growth theory shows that the long-term accumulation of human capital is the fundamental cause of economic growth.In this paper,the factors of human capital flow are incorporated into the endogenous economic growth model,and the choice of the path of human capital flow driving economic growth is studied.Combined with the actual situation of China,the household registration reform system is taken as the background,and the spatial econometric model is used to empirically test.This paper firstly reviews the research status of endogenous economic growth theory and human capital theory,as well as the measurement method of human capital and human capital flow.The factors of human capital flow are incorporated into the endogenous growth model of the two sectors of Uzawa-Lucas,and the improved Uzawa-Lucas model is established and analyzed as the theoretical basis of this paper.It proves the driving effect of human capital flow on economic growth and its action path theoretically.Secondly,we can measure the stock of human capital in each region by measuring the rate of return of education through Minser equation.Third,use Lowry gravity model to measure the flow of human capital.Finally,based on the Improved Uzawa-Lucas model,a spatial econometric model is constructed to verify the relationship between human capital and economic growth in China during 2005-2019 under the condition of human capital flow.The empirical results show that the stock of human capital promotes China’s economic growth and the flow of human capital has a positive impact on China’s economic growth.Finally,according to the above analysis conclusions,relevant countermeasures and suggestions are put forward to improve regional human capital accumulation and utilization efficiency and promote long-term stable economic growth.
