Abstract：Recently, as an emerging accommodation product, B & B has triggered changes in the tourism market. It can fully meet the personalized and diverse needs of tourists and become a new growth pole for tourism destinations. Taking Nanjing as an example, we used crawler software to obtain the data of Airbnb's B & B, relied on the DBSCAN clustering algorithm to identify the clusters of B & B in Nanjing, and analyzed the spatial distribution characteristics of B & B with the help of the spatial variation function model. Finally, the geographically weighted regression model was used to explore the impact and spatial differences of eight indicator factors in five dimensions, including transportation, commerce, population level, tourism resources, and internal relationships in the industry. The results show that: 1) The agglomeration effect of B & B space in Nanjing is significant, forming a 5-level 14-cluster of "25124" pattern and presenting a spatial layout characteristic of "two horizontal and two vertical" tic-tac-toe shape; 2) The density distribution of B & B has a certain spatial heterogeneity, and the nugget coefficient of the spatial variation function reaches 0.093, indicating that there is a strong distribution of B & B spatial autocorrelation. 3) Different factors have great heterogeneity in the direction and influence of the spatial pattern of the B & B.
