Abstract: The chip industry is a key industry supporting modern science and technology and economic development, but its long industrial chain and complex global competition and cooperation pattern make it being significantly impacted by external shocks. Especially in recent years, the coronavirus epidemic and the Sino-US trade frictions have a huge impact on China's chip industry. Facing complex and changeable external environment, it is urgent to examine the risks faced by China's chip industry from the perspective of network resilience. Based on the complex network theory, this study constructed a multi-dimension industrial network from business, technology and organization, and used the social network analysis method to compare and analyze the change of industrial networks under the epidemic impact and trade impact scenarios. The impact of the epidemic and trade friction will lead to the increase of the degree of dispersion and fragmentation of the chip industry network. After different cities were affected by the epidemic, the three types of networks in the chip industry were affected to different degrees. Compared with the impact of the epidemic, the loss of the toughness of the chip industry network structure caused by the trade blockade is more serious. This study has enriched the theory of industrial toughness and provided decision-making reference for improving the risk prevention and control ability of the chip industry.
