Identification of Key Links in Manufacturing Industry Chain
In order to identify the key links in China's manufacturing industry chain and ensure its autonomy,controllability,safety,and reliability,this article constructs a neoclassical economic growth model with the upstream,midstream,and downstream of the industrial chain.We study the output elasticity of the upstream to downstream link in the industrial chain under equilibrium conditions,that is,simulating and analyzing the economic mechanism.And we establish an SVAR model based on the manufacturing industry chain network to identify key links in the resilience of the industry chain.Furthermore,empirical analysis based on China's input-output data from 2000 to 2020 is conducted from the perspective of enhancing the elasticity and resilience of the manufacturing industry chain.The results show that:(1)For the midstream to downstream link of the manufacturing industry chain,the output elasticity is greater than that of the upstream to midstream link.It means that midstream to downstream link is the key to improving the added value of the manufacturing industry chain,and the synergistic improvement of output elasticity in each link of the industry chain will produce an"amplifier"effect;(2)For the upstream to midstream link of the manufacturing industry chain,the resilience is stronger.The key to ensuring the autonomy,controllability,safety,and reliability of the entire manufacturing industry chain is to concentrate advantageous resources and work together to tackle the low resilience link from the middle to the downstream.Therefore,this study provides empirical evidence and policy implications for optimizing the structure of China's manufacturing industry chain and improving the industry chain security.
