Analysis on the Spatial Structure of Tourism Economy of Chengdu Chongqing Urban Agglomeration

In this paper, 16 prefecture level cities in Chengdu Chongqing urban agglomeration are taken as spatial research units, and social network analysis method is used to analyze the characteristics of tourism economic spatial network structure of Chengdu Chongqing urban agglomeration from network density, network centrality, structural hole level and other indicators. It is found that: at present, Chengdu Chongqing urban agglomeration is not closely linked in tourism economic space, regional tourism development is not balanced, and there is an obvious core edge structure. As the central cities of Chengdu Chongqing city group, Chongqing and Chengdu have obvious competitive advantages, and the trend of tourism flow radiates from the core cities is obvious. The spatial network structure affects the performance of tourism industry by promoting and restraining the ability of attracting and radiating tourism flow. The development of regional tourism industry needs to pay attention to the optimization of spatial distribution of tourism economy.
