Effect of government subsidies on supply chain decision-making and coordination in the context of COVID-19
Considering the two-stage supply chain composed of a leading retailer and a manufacturer under the background of the COVID-19 epidemic, the retailer determines the anti-epidemic effort level and bears the corresponding costs, and the manufacturer determines the cost-sharing rate under the coordination strategy. This paper analyses the pricing decision, anti-epidemic effort level and cost-sharing rate of supply chain under different government subsidy measures and coordination strategies. Finally, a numerical example is given to verify the applicability of the conclusion and the model. From the perspective of Stackelberg game, we find that under the background of the epidemic, government subsidy measures, coordination strategies and increasing marginal income of anti-epidemic efforts are conducive to higher anti-epidemic efforts and social welfare level. And the government can obtain the maximum anti-epidemic efforts and social welfare level by subsidising manufacturers with cost sharing.
