The concept of “new node” is introduced, and the domestic tourists to Shenzhen are taken as the research object, by which to expand tourism nodes. Then, questionnaire survey is used to collect the travel information, and social network analysis method and spatial analysis technology are employed to reveal the structure characteristics of tourism flow network. The results show that the spatial flow of tourists is not limited to traditional nodes. New types of nodes have become increasingly prominent in the tourism flow network, exhibiting excellent flow control capabilities. Each popular tourist route contains at least one new node. Traditional nodes still serve as the starting point of tourist routes, but are no longer the terminal points. Tourists are now more inclined to arrange their final itinerary in cultural tourism business complexes. There is a core/sub-core/periphery structure in Shenzhens tourism flow. The nodes in the core area have a significant agglomeration effect. From the perspective of spatial structure, the tourist flow of Shenzhen is mainly distributed in the south and west, while the north and east are sparse. And it is mainly concentrated in the three districts of Nanshan, Futian and Luohu in the south, especially the OCT Tourist Resort.
