Abstract: COVID-19 has an impact on the global supply chain,which is mainly manifested in the simultaneous interruption of production capacity and demand.To explore the impact of government subsidy strategies on recovery in the context of supply chain interruption,the low-demand products during the epidemic were used as the research object,and the government's choice of subsidies for production capacity and demand interruption as a recovery strategy.The cumulative profit of supply chain members was taken as the recovery index,and system dynamics was used to construct the "manufacturer-distribution center" secondary supply chain.The changes in cumulative profits for different subsidy options were simulate under partial and complete interruption scenarios.The simulation results showed that the choice of government subsidy strategies under different interruption scenarios had different effects on the supply chain recovery effect.In the scenario of partial demand interruption,government subsidies for manufacturers with interrupted production capacity would make the supply chain recovery better.In the scenario of complete demand interruption,government subsidies for distribution centers with interrupted demand would make the supply chain recovery better.
