Abstract: The IC industry is one of the important indicators to measure a country's scientific and technological strength and economic level. This paper analyzes the internal and external environment of China's IC supply chain, studies related important influencing factors for its vulnerability, and proposes a new method of systematic evaluation to quantitatively analyze the vulnerability of China's IC supply chain. This paper regards exposure, sensitivity, and restorability as the three main measures of the vulnerability of the IC supply chain, establishes an indicator evaluation system, and uses the correlation degree as the indicator weight through the improved gray correlation method. In this way, this paper separately calculates the influences of the three measures for the vulnerability of the IC supply chain, and finds out the significant impact indicators. The analysis shows that the overall vulnerability of China's IC supply chain is relatively high, especially in areas such as key equipment, EDA software and professional talents. In order to break this international monopoly model, this article proposes that at the macro level, it is possible to restart major national projects, increase resource input in the IC industry, build a good IC supply chain ecological model, and form cluster development; in the technical field, it is necessary to improve talent training system, focus on breaking through key software and hardware technologies, and achieve IC products independence.
