Abstract: The rapid development of digital economy has accelerated the scale expansion of China's semiconductor industry. Chip is the core of high-end manufacturing industry, and the semiconductor industry is the key area of China's economic transformation and upgrading. However, under the impact of China-US trade friction and the overseas epidemic continues to expand, the vulnerability of China's semiconductor industry chain increasingly improved. Based on the industrial security concept from the perspective of global value chain, this paper constructs a index system of industrial chain security of China's semiconductor industry. It shows that in the short term, the industrial security declined significantly due to the superimposed impact, and decreased technological control and industrial chain participation are the main factors driving the decline. In the long run, in order to resist external risks, the security of China's semiconductor industry chain is increasingly improve, but the level is still low. Therefore, we should seize the opportunity of technological revolution and the wave of the digital economy to comprehensively improve the resilience and security of industrial chain by strengthening the industrial foundation to enhance the controllability of technology, making up for the shortcomings of industries to consolidate the industrial foundation, and increasing government support to consolidate our global consumption presence.
