Abstract
In the face of the impact of the epidemic on the industrial chain and supply chain, it is an inevitable requirement for industrial development to ensure the dynamic balance of the supply chain. Supply chain is the basis for the generation of industrial chain. Industrial linkage can promote the rational layout of industries. The operation mode of supply chain is the main driving force of industrial linkage. To build a dynamic and balanced supply chain, we must focus on symbolic industries and adopt measures of chain protection, chain supplement, chain creation and chain financing.
