Abstract: In this paper, 13 cities in the Beijing-Tianjin-Hebei Region are selected as research objects, based on Membership Function Coordination Model (MFCM), the tourism synergistic development degree was measured; the social network analysis method (SNA) and Exploratory Spatial Data Analysis (ESDA) tools were employed to study the spatial evolution characteristics of tourism synergistic development; then the influencing factors was studied by the Grey Correlation Analysis (GCA). The result showed: during the inspection period, the tourism synergistic development degree increased significantly, and the regional network has basically formed. The coordinated development of tourism among cities in the Beijing-Tianjin-Hebei region has been significantly improved; The Tourism Synergistic Development Network density increased; Cities such as Qinhuangdao, Zhangjiakou and Chengde were the key areas which promote the synergistic development of the Beijing-Tianjin-Hebei region; From the regional characteristics, the spatial structure of the research area presented the pattern that south was relatively sparse, and north was densely. There is a significant positive spatial correlation between cities within the region, while the spatial aggregation situation showed a increasing trend year by year. Judging from the research conclusions of Gray Correlation Analysis, ecological environment is the primary factor affecting the coordinated development of tourism, innovation ability has an important impact on improving the level of tourism synergistic development.
