Abstract: With the methods of literature review and interview, this paper constructs a framework from the perspective of the process and stakeholders involving government purchasing public sports services. It analyzes the risks and stakeholders in the process of project design, budget preparation, organization purchase, contract performance and evaluation, etc., including the risk of supply-demand contradiction caused by information asymmetry between the design and beneficiary entities, the risk of unclear target and opportunity cost loss caused by unclear purchasing boundaries of public sports services, and the risk of budget variance caused by pricing difficulties in "soft" public sports service projects. In response to the above-mentioned risks and their causes, 15 prevention strategies has been accurately designed, including establishing a mechanism for expressing public sports service demand, scientifically setting and calculating purchase targets, comprehensively calculating the cost price structure, and clarifying the proportion of total purchase service budget, etc.
