Research On The Effect Of Economic Policy Uncertainty On Industrial Structure Optimization And Upgrading

China's future industrial structure transformation and upgrading face new requirements: improve the development level of the service sector,so as to achieve the optimization and upgrading of China's industrial structure.The optimization and upgrading of the industrial structure is conducive to the realization of China's goal of being at the middle and high level of the global value chain.In recent years,economic policy uncertainty happens frequently,which has a great impact on China's economic development.Therefore,it is particularly important to examine the influence direction and influence channels of economic policy uncertainty on industrial structure optimization.Economic policy uncertainty data and industrial structure data from 2003 to 2016 were selected to explore the impact of economic policy uncertainty on industrial structure optimization by panel regression method.It is found that the increase of economic policy uncertainty has a significant positive promoting effect on the optimization and upgrading of industrial structure.Economic policy uncertainty through technological innovation channels to enhance their own core competitiveness,eliminate backward production capacity,promote the birth of new industries,improve labor productivity,improve the division of labor and the structure of demand.Finally promote the optimization and upgrading of the industrial structure.Through the channel of outward foreign direct investment,the scale effect is formed in the home country,so as to reduce the average cost,improve the economic benefits and promote the process upgrading of the home country's enterprises,so as to promote the optimization and upgrading of the home country's industrial structure.From the perspective of economic policy uncertainty,this paper provides feasible suggestions for the optimization and upgrading of China's industrial structure.
