The Impact Of The Quality Of Intermediate Products On Manufacturing Global Value Chain

The world is currently undergoing major changes unseen in a century.Trade protectionism is on the rise,the process of globalization is blocked,and the global spread of the new crown epidemic is superimposed.The manufacturing industry is facing a severe external environment to achieve its rise in the global value chain.At the same time,China’s manufacturing industry is facing the domestic development needs of realizing high-quality transformation and upgrading the global value chain.In this context,this paper combines theoretical research analysis and empirical research analysis to explore the impact mechanism of the quality of intermediate product on manufacturing global value chain,as well as the moderating effect of trade barriers on the quality of intermediate product.In terms of theoretical analysis,this paper analyzes the effect mechanism of the intermediate product quality on the global value chain basing on the three theoretical of related industry support effect,mass transfer effect and technology spillover effect.And according to the trade barrier effect,this paper theoretically analyzes the mediation mechanism of trade barriers on the intermediate product quality.In terms of empirical analysis,This paper uses the "three-dimensional" panel data of 22 manufacturing industries in 41 countries from 2000 to 2014,and measures the quality of intermediate products based on the proportion of high-tech intermediate products and the proportion of capital-intensive intermediate products.Taking Luxembourg,which has a higher degree of transformation,as the benchmark country to measure the degree of trade barriers,and uses a fixed effect model to carry out a mechanism test.The empirical research results show that:(1)On the whole,whether it is the quality of intermediate products based on the proportion of high-tech intermediate products or the quality of intermediate products based on the proportion of capital-intensive intermediate products,the quality of intermediate products will significantly improve the status of global value chain,but trade barriers will significantly weaken this promotion.(2)In the grouping of 25%-75% of the quality of intermediate products measured based on high-tech intermediate products,the quality of intermediate products will significantly promote the rise of the status of global value chain.(3)In the 25%-75%grouping of intermediate product quality measured based on capital-intensive intermediate products,there is a significant positive correlation between the quality of intermediate products and the status of global value chain.(4)Whether in developing countries or developed countries,the quality of intermediate products based on the proportion of capital-intensive intermediates will significantly promote the status of global value chain.However,the quality of intermediate products measured based on the proportion of high-tech intermediate products has the characteristics of national heterogeneity.In developing countries,the quality of intermediate products measured based on high-tech intermediate products still significantly improves the status of manufacturing global value chain.However,in developed countries,the quality of intermediate products based on high-tech intermediate products do not significantly promote the rise of the status of global value chain.(5)Whether it is the quality of intermediate products measured based on the proportion of high-tech intermediate products or the quality of intermediate products measured based on the proportion of capital-intensive intermediate products,their role in promoting the status of global value chain varies from weak to strong.The negative effects of trade barriers are also varies from weak to strong.Finally,on the basis of theoretical analysis and empirical research results,this paper puts forward four suggestions for helping China’s manufacturing industry to achieve high-quality transformation and to achieve its rise in the global value chain:(1)manufacturing industry increase the number of high-tech intermediate goods and capital-intensive intermediate products.(2)upgrade the supply chain system of the manufacturing industry.(3)promote trade liberalization.(4)enhance the independent innovation capability and capital investment of the domestic manufacturing industry.
