While spatial justice is a critical issue in socio-spatial research, it has not yet received sufficient attention in tourism studies. The phenomenon of unbalanced spatial development caused by mutual competition among various stakeholders in tourism destinations is widespread. As such, the mechanism of realizing spatial justice in tourism needs to be strengthened. This paper uses the Tibet Autonomous Region as a case study to analyze the causes and characteristics of spatial imbalance in tourism development from the perspective of spatial justice and explores the paths to realize spatial justice in tourism. Results showed that the government, tourist enterprises, and locals are the primary stakeholders in tourist spatial competition and negotiation. In the process of mutual consultation and balance of rights and interests, these three parties jointly develop and utilize the spatial resources of tourist sites. In order to protect the spatial rights and interests of vulnerable residents, various tourist stakeholders in Tibet Autonomous Region have taken multiple measures to increase residents’ participation in tourist space production and distribution of interests. With the possession of resources and the power of policy-making, the government and the tourist enterprises have a decisive influence on realizing the spatial justice of locals.
