An Empirical Study On The Influence Of China's Industrial Structure Optimization On Regional Economic Convergence

The coordinated development of regional economy will not only affect people's quality of life,but also an important development strategy that directly relates to the national economic outlook.China's vast territory,vertical horizontal area is vast,in the course of years of economic development and evolution,the regional economy has not been balanced development,there has been a growing regional gap phenomenon,and regional economic development gap is the dynamic change from the regional economic growth rate decided.The industrial structure as a direct effect of human activities on the macroeconomic performance at the same time,whether the coordination of industrial structure can affect the economic development speed and development potential of the region,so from the perspective of industrial structure optimization to study the regional economic convergence problem for improving the economic development of different regions has important practical significance.On the basis of combing the existing theories,this paper chooses the industrial structure optimization as the rationalization of the industrial structure,the advanced structure of the industrial structure and the sustainable development of the industrial structure,and analyzes the rationalization of the industrial structure from the above three perspectives The paper analyzes the spatial distribution and development trend of China's provincial economy by spatial correlation analysis and absolute convergence analysis.Then,based on the panel data of 31 provinces and autonomous regions in China from 2001 to2015,the economic opening level is selected as the threshold variable,and the fiscal expenditure,foreign direct investment,fixed asset investment and humancapital are taken as the control variables.According to the relevant theoretical model This paper constructs the conditional convergence threshold model for the influence of industrial structure optimization on regional economic convergence.This paper examines the threshold effect of China's industrial structure optimization on regional economic convergence from the national level and the three regional levels.The conclusion of the empirical research includes the following aspects:First,with the threshold of economic opening as the threshold variable,there are some conditions in the national provincial level,and the industrial structure optimization has significant double threshold effect on the regional economic convergence,the threshold value Respectively,when the economic opening level across the two thresholds,respectively,the impact of industrial structure optimization on the regional economic convergence first from the negative role to positive role,and then gradually strengthened;second,from the three regions At the same time,there are no convergence in the eastern and western regions,and there is no convergence trend in the central region,and the three regions are confirmed that there is a single threshold effect of economic open level.Thirdly,from the point of view of control variables,The three major regional economies have played a significant role in promoting the other variables on the three regional economic convergence is not the same.Finally,aiming at the above research results,this paper puts forward some useful suggestions.
