Research On The Impact Of Services Opening On The Upgrading In Global Value Chain Of Manufacturing

Because of reform and opening-up,Chinese economic construction has made tremendous achievements,and the gradual loss of labor force advantage requires us to urgently create a transformation of manufacturing industry at a low-end value chain status.This also conforms to the new trend of global international trade division,and is the necessary process of integration into the global value chain.The service industry connecting the production chain around the world is the key determinant to enhance the status of domestic manufacturing value chain.In order to meet the needs of national economic construction,it is urgent to expand the openness of service industry.This paper studies the impact and significance of service industry openness to the upgrading of manufacturing global value chain from both theoretical and empirical perspectives.Firstly,on the basis of domestic and foreign scholars' theoretical research on the current situation of service industry opening up,GVC status of manufacturing industry and its measurement method,etc,service FDI penetration,the service trade penetration,and export sophistication of manufacturing industry in sample countries are calculated,which are used to indicate the degree of service industry opening up and the GVC status of manufacturing industry respectively.The opening degree of the whole service industry is steadily rising,the export sophistication of manufacturing has a good development trend.However,the opening degree of developing countries is less than that of developed countries,and manufacturing industry is also at a critical juncture of transformation and upgrading.Secondly,it explores the action mechanism of service industry opening to a country's manufacturing global value chain status,that is,specialization effect,intermediate input effect,knowledge spillover effect and competition effect.Then,Based on the dynamic system GMM model,this paper first takes China's subdivided manufacturing industry as the research subject,calculates the intrinsic influence of service industry opening on the export sophistication of manufacturing,and conducts an empirical analysis on the relationship between service industry openness and global value chain upgrading of manufacturing industry.Considering the heterogeneity of countries,the panel data of 20 countries are selected to explore the potential links between the upgrading of manufacturing industry and the opening of serviceindustry and study the differences and similarities of the development rules between developed and developing Countries from the macro sample.According to the empirical results of GMM model and the theoretical mechanism,the mediating variables are set to test the path of service industry opening affecting the upgrading of manufacturing industry through mediating effect test.Finally,on the basis of summarizing the conclusions of the study,the paper puts forward policy suggestions for the further upgrading of China's manufacturing industry in the global value chain.
