Study on the Spatial Structure of Tourism Economy in Middle Area of China Based on Social Network Analysis

With the comprehensive economic strength of the Middle Area of China, the tourism economic ties more closely within the region, regional tourism cooperation more in-depth, a higher demand on the regional tourism spatial structure. This paper analyses the tourism economic relations and structure of48 cities in the Middle Area of China, based on related theories of the tourism spatial structure, by the use of the social network analysis, achieves4 conclusions: 1 Spatial tourism economic link degree of the Middle Area of China is low, but tourism economy affiliation levels of the 6 city subgroup are different; 2 tourism integration level of the changsha-zhuzhou-xiangtan city cluster,Wanjiang City Belt and Taiyuan economic circle is higher, but Wuhan city circle low level; 3 accessibility of Wuhan, Zhengzhou, Hefei, Luoyang, Changsha, Jiujiang,Nanchang is good, most close economic link, but spatial tourism economic link network is an imbalance, the core status of Wuhan,Zhengzhou, Hefei, Luoyang, Changsha, Nanchang is high; 4there are 3 subgroups of 1 first center in spatial tourism economy network of the Middle Area of China, link between subgroups and Wuhan city is more closely, and the relationship between subgroups is less, there was a network hierarchical structure. Finally,put forward proposal for spatial structure optimization and barrier-free integration in tourism economy of the Middle Area of China.
