长三角城市群基础设施与旅游经济耦合协调时空格局演变及驱动机制OA北大核心CSTPCD

Understanding the relationship between infrastructure and the tourism economy is crucial for optimizing infrastructure planning and enhancing the tourism sector's quality and efficiency.Focusing on the Yangtze River Delta(YRD)urban agglomeration,this study establishes a comprehensive evaluation index system for infrastructure levels and tourism economic development.Using a coupling coordination model,this research analyzes the spatio-temporal evolution characteristics of their development and employs geographic detectors to investigate the driving mechanisms.Results indicate:1)A steady upward trend in both the comprehensive evaluation index and coupling coordination degree of infrastructure and tourism economic development,with their coordination level transitioning rapidly between moderate and extreme coordination.Significant inter-provincial differences in coupling coordination are observed,with a spatial heterogeneity pattern of"Shanghai＞Jiangsu＞Zhejiang＞Anhui".2)The coupling coordination degree exhibits a spatial distribution of"high in the east and low in the west,high in the center and low in the north and south",with high and low coordination zones showing a spatial"expansion-convergence"trend.During the study period,the number of cities with lagging infrastructure increased gradually,mainly concentrated in Zhejiang and Shanghai regions.Meanwhile,cities with lagging tourism economic development converged and gathered in the northern part of the Yangtze River Delta.3)The coupling coordination of infrastructure and tourism economic development is driven by various factors,including economic pulling force,government regulation force,urbanization driving force.The coordinated development of the two is driven by a comprehensive mechanism formed by eight driving forces,including economic operation and structural transformation mechanism,policy regulation and open cooperation mechanism,population agglomeration and consumption driving mechanism,and talent guarantee and technological innovation mechanism.
