【摘要】 系统刻画长三角城市群城市韧性空间关联网络特征，探讨其旅游经济效应，这对于凝聚城市韧性合力，扩大城市韧性对旅游经济的网络溢出效应具有重要的实践价值。本研究以2006—2021年长三角城市群26市为研究对象，将城市韧性空间关联网络与旅游经济纳入同一研究框架，在测度长三角城市群城市韧性与旅游经济水平的基础上，多角度刻画城市韧性空间网络特征，并分析个体网络节点对旅游经济的直接效应、空间溢出效应与异质性特征。主要结论如下：(1)研究期内，长三角城市群城市韧性水平相对稳定，整体呈现东部水平突出，南北两翼城市韧性水平薄弱的格局；旅游经济水平呈现先增长后平稳下降的趋势。(2)长三角城市群城市韧性空间关联网络向复杂化、稠密化过程持续演化，网络结构中的“领导者”“接近者”“中介者”主要分布在经济发达城市。(3)长三角城市群城市韧性空间网络结构特征对旅游经济具有显著的正向影响与空间溢出效应，且间接效应的影响要高于直接效应的影响。(4)不同地区、不同类型城市的空间网络结构特征对旅游经济的影响存在一定差异。经济前十名城市、高人口规模城市的度数中心度对旅游经济的正向影响更为突出；经济非前十名城市、中低人口规模城市的中介中心度与接近中心度对旅游经济的正向效应更明显。最后，讨论了强化城市群空间关联以及政策保障对区域旅游经济可持续发展的实际意义。研究结论丰富了城市韧性与旅游发展效应的关联内涵，回应了城市韧性空间关联网络与旅游经济复杂关系的学术关切，为城市旅游可持续发展提供了支撑。更多还原

【Abstract】 The Yangtze River Delta urban agglomeration holds significant strategic importance. A thorough analysis of the network structure characteristics and their effects on regional tourism economic development can support the achievement of its goal of “integration of industry and city” and provide decision-making references for the high-quality construction of the Yangtze River Delta urban agglomeration. What’s more, systematically characterizing the spatial network features of urban resilience in the delta region and exploring its effects on tourism economy is of great practical value for enhancing the collective strength of urban resilience and expanding the network spillover effects of urban resilience on tourism economy. Focusing on 26 cities in the study area from 2006 to 2021, this study aims to incorporate its urban resilience spatial networks and tourism economics within a unified research framework. Methodologically, the study characterizes the features of the urban resilience spatial network from multiple perspectives and analyzes the direct effects, spatial spillover effects, and heterogeneous characteristics of individual network nodes on tourism economics based on the measurement of urban resilience and tourism economic levels in the delta. The main findings are as follows:(1) During the study period, the urban resilience level of this agglomeration remained relatively stable overall, exhibiting a distinct spatial pattern characterized by stronger performance in the eastern region and relatively low resilience in the northern and southern wings. The tourism sector witnessed an initial increase and then underwent a gradual decline.(2) The spatial network of urban resilience has continued to evolve towards greater complexity and density, shaping an evolutionary trajectory that transitioned from “localized point-to-point linkages” to “radiation patterns centered on Shanghai and Suzhou”, and ultimately to “a multi-nodal structure characterized by coordinated agglomeration and radiating influences”. In the network structure, key roles such as the “leaders”, “proximates”, and “intermediaries” are mainly concentrated in economically developed urban centers.(3) The spatial network structure characteristics of urban resilience have a significant positive impact on the tourism economy and exhibit spatial spillover effects, with indirect effects being more substantial than direct effects. Ignoring spatial effects would result in an underestimation of their impact.(4) The impact of spatial network structure on the tourism economy varies by region and city type. Cities with advanced economies and large populations show a more obvious positive effect of degree centrality on the tourism economy. In contrast, cities with less developed economies and smaller populations exhibit stronger positive effects from both closeness centrality and betweenness centrality on tourism development. The practical significance of this study lies in strengthening the role of spatial connections within urban agglomerations and policy support in promoting the sustainable development of regional tourism economies. Meanwhile, the findings enrich the research on urban resilience and the effects of tourism development, addressing academic concerns regarding the complex relationship between urban resilience, spatial connectivity networks, and tourism economies.更多还原
