Coordinated Development of High-Quality Tourism Development and Residents'Common Prosperity in the Yangtze River Delta Urban Agglomeration
The high-quality development of tourism is an effective way to promote the common prosperity of residents,and pro-moting the residents'common prosperity can further improve the level of high-quality tourism development.The coordinated de-velopment of the two is conducive to the realization of Chinese path to modernization.Taking the Yangtze River Delta urban ag-glomeration as the research object,the coefficient of variation and comprehensive evaluation method are used to measure the de-velopment level of high-quality tourism development and common prosperity of residents in cities of the Yangtze River Delta ur-ban agglomeration from 2010 to 2020.Then the coupling coordination degree model and synchronous development model are used to clarify the coupling coordination status and relative lag factors between the two systems.Finally,exploratory spatial data analysis and standard deviational ellipse are used to explore the spatiotemporal evolution characteristics and trends of the cou-pling and coordination between the two systems.The results are shown as follows.① During the study period,the average cou-pling coordination level of high-quality tourism development and common prosperity of residents in the Yangtze River Delta ur-ban agglomeration fluctuated between 0.39 and 0.49,belonging to a medium low level,with a large range,floating between 0.41 and 0.63,showing a cyclical change of"rise-fall-rise-fall".② The coupling coordination degree of the two system fluctuated re-peatedly between imbalance and coordination at the urban scale,and the high-quality tourism development and the development of residents'common prosperity in most cities of the urban agglomeration were basically synchronized.③ The coupling coordi-nation degree of the two systems had obvious spatial differentiation characteristics of"high in the east,low in the west",and the coupling coordination center had a tendency to move eastward.The hot spots of the coupling coordination degree were concen-trated in the cities at the estuary of the Yangtze River Delta,while cold spots were concentrated in the cities in the western re-gion of the Yangtze River Delta urban agglomeration.
