旅游高质量发展是促进居民共同富裕的有效途径，而推进实现共同富裕目标能进一步提升旅游高质量发展水平，二者协调发展有利于实现中国式现代化。该文采用变异系数法和综合评价法测度2010—2020年长三角城市群各地市旅游高质量发展、居民共同富裕发展水平，并利用耦合协调度模型、同步发展模型明晰两系统间的耦合协调状况及相对滞后因素，最后引入探索性空间数据分析、标准差椭圆探究两系统间耦合协调的时空演变特征及发展趋势。结果表明：研究期内长三角城市群旅游高质量发展与居民共同富裕耦合协调水平属于中等偏低水平，整体呈现“上升—下降—上升—下降”的周期性波动，极差(0.41～0.63)较大；市域尺度下两系统耦合协调度在失调与协调之间反复变化，大多数地市两系统发展基本同步；两系统耦合协调度空间分布呈现出“东部高、西部低”的分异特征，热点区集中分布于长江入海口地市，冷点区聚集于长三角城市群西部，呈“西北—东南”方向性特征且随着时间演变愈加显著，耦合协调中心具有向东偏移趋势。

The high-quality development of tourism is an effective way to promote the common prosperity of residents, and promoting the residents′ common prosperity can further improve the level of high-quality tourism development.The coordinated development of the two is conducive to the realization of Chinese path to modernization.Taking the Yangtze River Delta urban agglomeration as the research object, the coefficient of variation and comprehensive evaluation method are used to measure the development level of high-quality tourism development and common prosperity of residents in cities of the Yangtze River Delta urban 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 coupling and coordination between the two systems.The results are shown as follows.(1) During the study period, the average coupling coordination level of high-quality tourism development and common prosperity of residents in the Yangtze River Delta urban 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 repeatedly 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 coordination 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 concentrated in the cities at the estuary of the Yangtze River Delta, while cold spots were concentrated in the cities in the western region of the Yangtze River Delta urban agglomeration.
