In the face of the pressure generated by changes in the external environment,China's key core technology industry chain has a fragile response such as"broken chain"and"dropped chain".Based on the ecological vulnerability theory,a vulnerability assessment system for the industrial chain of key core technologies is constructed from the three dimensions of exposure,sensitivity and adaptability.Taking the industrial chain of integrated circuits as an example,the entropy weight topsis method is used to evaluate the vulnerability of the whole industrial chain,sub-chain and regional industrial chain.The results show that the integrated circuit industry chain vulnerability index shows a slight fluctuation trend of first rising and then falling.The annual exposure index of chip sub-chain is higher than that of equipment and material sub-chain and electronic component sub-chain,but the industry chain shows strong adaptability at the same time.Limited by exposure factors,the integrated circuit industry chain vulnerability index in eastern China is higher than that in central and western China.This paper enriches the evaluation research of key core technology industry chains from the perspective of vulnerability,and provides empirical evidence for shaping resilience pathways.
