Abstract: The purpose of constructing sports public service system is to satisfy the ever-changing public sports demand. As the core of the system engineering, " publicness" plays the guiding function with both overall and local characteristics. The research believes that publicness mainly lies in the four aspects of the service direction, service targets, operation and supervision mechanism, and service concept, standing for philosophy of being “owned by people”, “enjoyed by people”, “ruled by people” and “for people” respectively. The paper also point out that publicness belongs to the government, the public and the mechanism. The realization largely depends on social construction as the environment, public space creation as the spatial basis, government credibility as the power basis and the construction of fair mechanism as the system basis.

Key words: sports public service system, government, publicness, public
