The research results show that "perceived value," "perceived risk," "conformity behavior," and "product involvement" can effectively affect the purchase intention of domestic tourism products in the current severe epidemic of COVID-19. Taiwan's tourism industry can start from the development of "epidemic tourism," "group tourism," and "family tourism" in order to retain domestic tourists for surviving in the tourism industry.
