Development and evolution of adaptive cycle stage and driving mechanism of China's Ttourism economy
In order to identify the cyclical stages of the adaptive cycle of China's tourism economy since the 21st century,this study used spatial analysis and geographical detectors to explore its evolution and impact mechanism.The results show that:1)China's tourism economy presents a'rapid growth-volatility release-reorgan-ization and redevelopment'of the adaptive cycle of evolution process.2001-2007 was a period of rapid growth(r-K stage),which means sustained and stable development in rapid growth.The period from 2008 to 2014 was a stage of volatility release(Ω-K-Ω stage),which was characterized by a shock development trend after repeated shocks in the stable development.Structural rigidity and weak growth of the tourism economy were important features of this stage.2015-2020 was the restructuring and redevelopment period(α-r stage),which means redevelopment on the new de-velopment path after restructuring.In 2020,as the end of this development phase,the impact of Covid-19 was signi-ficant,there was the possibility of discontinuous development into the release stage.2)The evolution characteristics of different attributes are different.The spatial diffusion characteristics of potential dimension are significant,showing the spatial distribution characteristics along the southeast coast to the inland.The correlation degree has a certain tendency of'coastal and border railway'agglomeration.And the resilience showed obvious distribution characteristics of the'Hu line',and the high-level agglomeration in the southeast region was particularly significant.3)There are signific-ant differences in the developmental characteristics and driving forces at different stages of the adaptive cycle.The rapid development of macro-economy is the key driving force of strong adaptability of tourism economy in the period of rapid growth.Beijing,Tianjin,Shanghai and Guangdong have achieved super-stage development.The inland trans-fer of industries and the continuous improvement of ecological environment are important guarantee forces for the ad-aptability of tourism economy in the period of volatility release.The continuous optimization of industrial structure and the implementation of regional development strategy are the core supporting force for the adaptability of tourism economy in the restructuring and redevelopment period.The number of provinces,regions and cities with over-stage development has risen to 22.In the context of the new normal of economic development,the implementation of re-gional development strategies such as'the Belt and Road','coordinated development of the Beijing-Tianjin-Hebei re-gion'and'the Yangtze River Economic Belt'has brought more opportunities for the adaptive qualitative develop-ment of tourism economy in these regions.4)There are differences in the impact factors at different stages,showing the transformation of the impact factors from the marketization of tourism economy,to innovation co-operation and coordination and sustainability,and then to the joint promotion of hardware facilities and soft-ware innovation.Through the three-dimensional drive of potential(to lay the foundation),correlation(to co-ordinate cooperation)and resilience(to improve quality and upgrade),we will promote the renewal of factors,optimization of structure,improvement of functions and development of stages,gradually achieve the overall development of the tourism economy forward adaptability.
