Abstract: The integration of agriculture, culture and tourism promotes the sustainable development of rural tourism. However, the layout of rural public spaces is difficult to accommodate the needs of multiple groups. To alleviate the contradictions among the spatial demands and protection and renewal in tourism-oriented villages, based on the perspective of host-guest sharing and combined with the social network analysis method, this paper takes Xikou Village in Hangzhou City, Zhejiang Province as an example. Selecting indicators such as Network Density, Small World Index (SWI), Cliques, Degree Centrality and Betweenness Centrality, it constructs the public space network model, villager behavior network model and tourist behavior network model, and analyzes the differences in network structure characteristics from three levels: the overall network, the internal structure and the single-point distribution. The results show that the overall network of public spaces in Xikou Village is insufficiently complete, the internal structure stability of the villager behavior and tourist behavior network models is low, and the uneven distribution of spatial resources leads to isolated spatial nodes. Thus, strategies such as strengthening the setting of key nodes, improving the spatial sequence, and creating an integrated space of agriculture-culture and tourism shared by hosts and guests are proposed, in order to provide a reference for the adaptation and structural optimization of the 'space-behavior' network of the host-guest in the tourism-oriented villages.
