This paper focuses on the ways COVID-19 has facilitated the development of platform-based supply chains. Platform-based supply chains are of great research value as a new direction for supply chain development, especially in China. The first part of the paper summarizes the characteristics of the COVID-19 era around the world, the second part points out the situation of platform-based supply chains in China, and the third part analyses the promotion effect of the epidemic. As platform-based supply chains are still at an emerging stage, there are very few analyses and theoretical studies on their operation models, and for this reason this paper lacks empirical data.
