Research on the impact of the"chain length system"of the industrial chain on the transformation of trade structure
Based on the provincial trade panel data from 2017 to 2022,this paper empirically examines the impact of the"chain length system"of the industrial chain on the transformation of trade structure by using the difference-in-differ-ence method.The results show that the implementation of the"chain length system"in the industrial chain can effec-tively increase the proportion of general trade in total trade and promote the transformation of processing trade to general trade.The implementation of the"chain length system"of the industrial chain has a significant effect on the"quantity"of the trade structure in the eastern and northeastern regions,and the optimization of the"quality"of the trade structure in the eastern,central and northeastern regions is obvious.The industry heterogeneity of the"chain length system"to improve the"quantity"of the trade structure of the industrial chain is not obvious,but the heterogeneity of the industry to optimize the"quality"of the trade structure is significant.This paper puts forward policy suggestions for building a high-level chain length system from the aspects of cultivating the industrial ecology of the chain length industry,promo-ting the technological innovation of the industrial chain and supply chain,and strengthening the international cooperation of the industrial chain.
