Abstract: As a major public health emergency, the risk of an epidemic is a new but important research topic. From a new network topological perspective, this paper constructs an inter-city epidemic connection network due to the mobility of infected people based on COVID-19 and empirically examines the impacts of a city’s network position on its epidemic risk. We find that the inter-city epidemic is highly interconnected. A city’s network centrality has a positive and significant effect on epidemic risk. Further analysis shows that a city’s network centrality can amplify the epidemic spread risk. Hubei’s lockdown reduces the effects of a city’ s network centrality on epidemic risk.
