Since the implementation of the “National Fitness Plan (2021-2025)” issued by the State Council, it has entered the later stage of the “14th Five Year Plan”. The plan clearly states that it is necessary to do a good job in opening school sports venues to the society. However, due to a series of objective reasons, the operation of university sports venues to the outside world is not widespread. Through interview methods, senior professional title experts in university sports majors and employees who have been managing sports venues for more than 10 years were interviewed. The interview content was coded using nvivo12, and combined with literature data, the six major factors that restrict the external operation of university sports venues were summarized, namely: the special attributes of state-owned assets, the responsible units for venue management, the responsibility for venue operation safety, the use conflicts between inside and outside the campus, the complex problems brought by operation, and the venue management. Diversity of usage attributes. Through expert investigation method and combined with Analytic Hierarchy Process (AHP), analyze the factors that constrain the external operation of university sports venues, establish weights, and establish a constraint model. The establishment of the model is beneficial for university sports venue managers and relevant practitioners to have a deeper understanding of the current difficulties in the external operation of university sports venues. Guided by the constraint model, targeted solutions can be formulated to further promote the development of external operation of university sports venues, providing a certain theoretical reference.
