The Productivity Effect of China's Manufacturing Industry Chain Agglomeration
Giving full play to the advantages of industrial chain agglomeration to improve the total fac-tor productivity of China's manufacturing industry is the key way to cope with the restructuring of the global industrial chain and promote the modernization of China's industrial system.Based on the data from the China Industrial Enterprise database from 2003 to 2015 and the Input-output Table of China,this paper puts forward the theoretical hypothesis that the upstream and downstream agglomeration affects the total fac-tor productivity on the basis of the theory of specialization and diversified spatial agglomeration,constructs the industrial chain agglomeration index based on location entropy and input-output correlation,and uses a variety of econometric models to test the theoretical hypothesis.The results show that the upstream and downstream spatial agglomeration of the industrial chain can significantly promote the improvement of indus-trial TFP,and the effect of the downstream spatial agglomeration is greater than that of the upstream spatial agglomeration.Industrial market concentration plays an intermediary role,and the decline in the propor-tion of fixed assets can strengthen the promoting effect of spatial agglomeration of the industrial chain on TFP.Further analysis shows that the impact of industrial chain spatial agglomeration on TFP is heterogene-ous according to the internal development characteristics of the industry and the external growth environ-ment.This paper provides policy implications for promoting the high-quality development of China's man-ufacturing industry and the modernization of the industrial chain and supply chain from the perspective of industrial chain agglomeration.
