Abstract: Referring to the theory of Governance, New Public Service theory and Principal-Agent theory as well as existing law design, the present paper defines government's role in purchasing national fitness public services as policy supplier, service purchaser and order regulator. Based on the definition, the author analyzes government's role in purchasing national fitness public services, finding that: in reality, government works as "policy setter", "administrative leader", and "rational broker" rather than "policy supplier", "service purchaser" and "order regulator". To counter this problem, the author proposes that the feasible approaches to rectify government's role deviation include making clear government's position as "policy supplier", accelerating the transformation of government's role into "service purchaser" and government truly shouldering the mission of "order regulator", in hope of providing theoretical reference for the practice of governmental purchasing national fitness public services.
