Research on the influence mechanisms of digital economy on tourism economic resilience—empirical evidence from China

In recent years, the vulnerability of the tourism economy has been highlighted by public security incidents. To ensure high-quality development of the tourism industry, it is crucial to enhance tourism economic resilience (TER). Despite this adverse trend, the digital economy (DE) continues to develop robustly, bringing new vitality to the tourism industry and becoming an important means to enhance its resilience. Based on this, a panel fixed time effect model and a spatial lag model are constructed to study the impact mechanism of the DE on TER. The study finds that the DE has a significant direct positive impact on TER. Moreover, industrial structure optimization, innovation capacity, and human capital stock are all effective mediating mechanisms for the digital economy to enhance TER, and the mediating effect of industrial structure optimization is more obvious. The spatial spillover effect of the DE on TER is negative.
