Tourism spatial structure of urban agglomeration in the middle reaches of the Yangtze River based on social network analysis

Abstract Based on a revised gravity model, this paper establishes an evaluating indicator and model of the spatial structure of tourism economic linkages in urban agglomeration by using social network theory and method. Tourism spatial economic data of 56 urban in the urban agglomeration of the middle reaches of the Yangtze River were collected. With the help of Ucinet software, we discuss the tourism spatial structure features in the urban agglomeration of the middle reaches of the Yangtze River, and the tourism spatial structure of urban agglomerationis optimized by network density, centrality degree, structural holes, core-periphery structure and condensing subgroup model.
