Note: *** p < 0.01, ** p < 0.05, * p < 0.1. Standard errors are clustered at county level, which are in parentheses. “Yes” means the control variables and fixed effects indicated in the left column are included in the model. We include one day to ten days lagged variables of COVID-19 new cases and accumulative cases into the models.
