Huizhou villages are representatives of traditional villages and have a high historical, cultural, and tourism value. In view of the problems of low commercial efficiency due to the small scale of commercial space and the imperfect layout in Longchuan Village, Jixi County, Xuancheng City, Anhui Province, this research explores the spatial advantages of Longchuan Village’s commercial layout through an analysis of street and lane space syntax and a commercial space resistance model. The research on the spatial syntax of streets mainly focuses on the analysis of the spatial accessibility, line-of-sight integration, and spatial comprehensibility of Longchuan Village’s streets. The commercial space resistance model mainly studies the attraction of tourism resources to tourists in order to select the most suitable area for the layout of commercial space. The results of the analysis show the following: (1) The integration degree of traffic and the sight line is relatively high at County Road and Water Street in Longchuan Village, so these two places have better accessibility and more sight lines. (2) Longchuan Village has a good spatial understanding in a small area, so it is not suitable to distribute commercial space but rather to centralize it. (3) In the commercial space layout resistance model, the area around Water Street and Qixing Pond has the smallest spatial resistance and the greatest opportunity for population gathering, making it the most suitable for a commercial layout. On the basis of the analysis results, this paper puts forward an optimization strategy of Longchuan Village’s commercial space layout in a targeted manner to help Longchuan Village achieve a better commercial layout. The research contribution of this paper will help planners and architects to take advantage of space to plan the commercial space of traditional tourist villages so that they can exert a better commercial value and tourism effect and to promote the tourism development of traditional villages across the country.
