Does Green R&D Promote the'Made in China'Global Value Chain Leap?——New Evidence from Multivariate Cointegration Analysis of Export Quality Perspective
Under the trend of low-carbon development of the global value chain,how to break the long-term'embedding'of China's manufacturing industry rather than'leading'the high-end links of the global value chain is a realistic problem faced by China's high-quality trade development.Based on the world input-output data published by WIOD and the panel data of China's manufacturing industry,this paper empirically analyzes the impact of green R&D on the global value chain transition of"Made in China"and its mechanism by means of multiple cointegration analysis,ECM model and Granger causality test.The results show that green R&D is not conducive to the global value chain transition in the short term,but there is a long-term stable co-integration relationship between green R&D and global value chain transition in the long term.The quality of export products is an important transmission mechanism for green R&D to promote the global value chain transition.Compared with the low-intensity R&D input manufacturing industry,green R&D has a more significant promotion effect on the global value chain transition of high-intensity R&D industry.With the help of the nonlinear threshold cointegration model,it is found that the relationship between green R&D and global value chain transition is U-shaped.Only when green R&D intensity breaks a certain'threshold'can it stimulate the global value chain transition.There are significant differences in the speed and direction of the adjustment from'short-term fluctuation'to'long-term equilibrium'in different threshold intervals.The research conclusion has important theoretical and practical significance for breaking through the green trade barriers faced by the traditional manufacturing industry and promoting to the middle and high end of the global value chain.
