Study on the Tourism Spatial Structure in Beijing-Tianjin-Hebei Region

The Beijing-Tianjin-Hebei region is the core of economic growth in the northern China. Researches on the structure of the regional tourism network will help to speed up the process of the tourism integration in Bohai Sea, and give full play to the role of tourism in promoting economic integration. This paper analyses the tourism economic relations and structure of 13 cities (Beijing, Tianjin and 11cities in Hebei province) from the perspective of the network structure. The authors propose an improved gravity model, and make use of the social analysis to study the tourism spatial structure in Beijing-Tianjin-Hebei region, and then put forward some influential factors. The results show that the network density is 0.48, which belongs to the medium density net. From the perspective of core-edge, Beijing, Tianjin, Baoding and Shijiazhuang are at the core, while others are on the edge, which exist obvious layering network structure. In terms of small groups, there are two small groups in the network, and the tourism economic relations among the group members are more closely.
