ABSTRACTThe COVID‐19 pandemic forced the postponement of some international events, such as the Tokyo 2020 Olympic Games, which negatively impacted residents and the local tourism industry. Therefore, it is necessary to understand residents' support for hosting major sporting events. We surveyed 769 residents using a structural equation model and applied social exchange theory (SET) to analyse the 31st Summer Universiade and examine their support for hosting major sporting events. The results revealed a significant relationship between postponement risk perception and the perceived costs and benefits, which affected the residents' support for hosting major events. These findings confirmed perceived benefits and costs as key factors determining residents' support for/opposition to major events. We proposed the residents' postponement risk perception concept, integrated it into the event tourism research model, and expanded the explanatory power of SET in unconventional contexts, providing stakeholders with references for planning and hosting events under special circumstances.
