Abstract: As a tool to establish optimal order, standardization aids in creating a safe, fair, and well-regulated competitive environment for sporting events, advancing high-quality development within the sports industry and sector. By applying case studies and comparative analyses, this paper examines critical areas of standardized practices in organizing major single-sport events in foreign countries, summarizing the shared characteristics and insights that emerge during the standardization process. The findings highlight six primary domains of standardization for organizing such events: entry and approval standards, planning and operational standards, safety and risk control standards, procurement and anti-corruption standards, resource management and service standards, and sustainability standards. The study finds that common characteristics of event standardization include: comprehensive safety and security assurance as a central aspect in standard formulation, full-process standardization as the foundation for successful event organization, multi-stakeholder collaborative mechanisms as key governance measures, existing laws and regulations as essential guidelines for standard-setting and implementation, and knowledge management and transfer as core components in the use of event legacy and the development of sustainability standards. The research suggests that, in advancing standardization for major single-sport events in China, there should be an enhancement of the event safety and security standards framework and a full-process safety and security supervision mechanism; refinement of standards across various stages to build a seamlessly integrated system; optimization of collaborative mechanisms to strengthen government networks in the standardization process; improvement of the legal framework to elevate the authority of standards; and a focus on knowledge management to support the promotion and implementation of standards.
