This study explores the post-game utilization of venues at the 31st Summer Universiade and assesses respondents’ satisfaction with venue services. The study found that although large-scale sports events such as the Summer Universiade are held in China, the issue of venue utilization after the games has become an urgent problem that needs to be solved. Although a lot of manpower and material resources have been invested in the construction of modern sports venues, they often only focus on the requirements during the event and ignore the operation and utilization of the venues after the game. In this context, through a survey and analysis of 278 respondents, this study found that venue infrastructure and recreational and leisure facilities scored higher, but other aspects such as venue facilities, accessibility, service personnel, catering services, etc. scored lower Low. Respondent satisfaction is positively correlated with gender, but not significantly correlated with other demographic characteristics such as age, education, occupation, etc. In social services, product appearance is positively evaluated, but functionality and reliability are not. Finally, the study found that only reliability and transportation accessibility were positively related to satisfaction, emphasizing the important impact of transportation on venue reliability. In summary, this study provides important reference value for solving the post-match utilization issues of large-scale sports event venues. It is recommended that while improving service levels and facility quality, strengthen the function and reliability of social services and pay attention to transportation accessibility, to improve the satisfaction of using the venue after the game.
