Abstract: As a dual-engine for sports industry and sports enterprise development, sports events show a trend of rapid development in the process of economic and social development. Major sports events as well as mass sports events whose main purpose is common people participation, have prominent public nature, belong to quasi public products, have an ever increasing hosted number and social demand, are increasingly impacting on the government’s public ser-vice supply ability. Under such a background, public sports event service outsourcing becomes a currently beneficial choice for related departments. Public sports event service outsourcing is conducive to promoting government function transformation, in conformity with government function return emphasized by the core competitive strength theory and event professionalization requirements, conducive to resolving the entrusting-agenting misplacement of event supply, able to better lower event hosting cost and increase event service supply efficiency. Related departments should in-crease their awareness of the importance of public sports event service outsourcing, establish scientific, diversified out-sourcing modes, increase the cultivation of social organizations and competitive outsourcing service subjects with an independent relationship, and at the same time, establish a legitimate and limited outsourcing system, and intensify out-sourcing management ability.
