How do Key core technical Barriers affect Supply chain Resilience——Two-way multi-level Mechanism Analysis
In the context of increasingly complex international relations and the core technologies in key fields are sub-ject to foreign technical control,it is of great significance to analyze and deal with barriers of core technologies in key fields.Based on the quasi-natural experiment implemented in the Entity List,this paper investigates the influence of key technical barriers on supply chain resilience and their action path by using multi-stage difference-difference method.The results found that the key core technical barriers generally reduced the supply chain resilience,and the above conclusions remained valid after a series of robustness tests.The mechanism test found that the key core technical barriers have a combi-nation of positive and negative impacts on supply chain resilience.On the one hand,they have a negative impact on supply chain resilience by destroying the value chain of enterprises,and on the other hand,they also show positive effects through the innovation back forcing mechanism and the government strategic agglomeration mechanism to a certain extent.The con-clusion has important practical significance for the system to deal with the barriers of core technologies in key fields and im-prove the resilience of the industrial chain and supply chain in the face of external shocks.
