This study analyzes urbanization, disasters, and their impact on tourism development for RCEP (Regional Comprehensive Economic Partnership) countries. We use ADF (Augmented Dickey-Fuller) and PP (Phillips-Perron) tests, causality tests, quantile regression, and fixed-effect panel models on data from 1995-2018. Empirical results show that urbanization does not help tourism development in the low quantiles but does help in the high quantiles. Disaster-preventive measures and post-disaster reconstruction help the development of tourism. However, in developed countries, disasters are not conducive to the development of tourism. Urbanization is the Granger cause of tourism and carbon emissions. The increase in temperature, rainfall, and carbon emissions caused by urbanization do not contribute to the development of tourism. Based on this, we have proposed a series of urbanization development and disaster defense measures to promote the sustainable development of tourism in RCEP countries.
