How Does the Resilience of Semiconductor Supply Chain Affected by Major Power Competition ?

In the era of great power competition, Sino-US trade friction has become increasingly tense, especially in the high-tech industries represented by the semiconductor industry, which has created fierce competition. This study focuses on the risk of semiconductor supply chain interruption in the context of competition between major powers. Taking the Sino-US trade friction incident that began in 2018 as the research background and the semiconductor supply chain resilience as the research object, we construct an evaluation index system for the resilience of China's semiconductor industry chain and a score-matched difference-in-difference (PSM-DID) event impact assessment model uses Stata16.0 to process and calculate a total of 2424 samples from 2017 to 2022. Evaluate the impact of international uncertain events on the resilience of China's semiconductor supply chain through empirical analysis. The research results show that international uncertain events may have an adverse impact on the resilience level of enterprises related to China's semiconductor industry. Enterprises of different sizes have different impacts on the resilience of international uncertain events. The impact of international uncertain events on enterprise resilience There may be a certain lag in adverse effects. The research results help to correctly assess the impact of trade friction on the supply chain resilience of my country's semiconductor industry, and provide scientific support for the formulation of policies related to the semiconductor supply chain and the governance of multiple entities.
