Coordinated Situation and Dynamic Mechanism of Rural Tourism and Rural Revitalization in the Metropolitan Area of Xi'an

Metropolitan areas are an inevitable outcome of urbanization development. The countryside is the key problem restricting the quality of urbanization development in such areas. Rural tourism-driven revitalization is of considerable importance for the integrated development of urban and rural areas in metropolitan areas. Based on comprehensive development level and coupling coordination degree models, we used the fuzzy comprehensive evaluation method to calculate the coupling and coordinated development level of rural tourism and revitalization in the metropolitan area of Xi'an in 2021. Furthermore, we explored the dynamic mechanism of coordinated development in combination with typical cases. The results indicate the following: (1) In 2021, the overall level of rural tourism development was good, and the spatial difference exhibited a decreasing phenomenon from the core circle to the outer circle. (2) The coupling and coordination degree of rural tourism and revitalization is generally in a balanced state, which indicates that the core circle is superior to the peripheral circle in space. (3) The combined effect of "supply-demand-guarantee" is an important driving mechanism for the coordinated development of rural tourism and revitalization in the metropolitan area, in which "supply" is the basic factor for the coordinated development, "demand" is the core factor for the improvement of its coupling coordination level, and "guarantee" is the supporting factor for its sustainable development. This study enriches the theory of rural revitalization in metropolitan areas to a certain extent and provides new insights for improving the quality of urban and rural integrated development in metropolitan areas.
