Abstract::Optimizing the internal structure of the policy system and improving the long ̄term mechanism are important pre ̄ requisites for promoting a sound development of adolescents′ physical fitness in accordance with the law. From the perspec ̄ tive of policy toolsꎬ this paper conducts a quantitative analysis of 37 national youth physical health policies since 2000 through content analysis with policy tools as the X dimension and policy implementation as the Y dimension. The results show that supply ̄side policy tools are underusedꎻ demand ̄side policy tools are absent as a wholeꎻ and environmental ̄side policy tools are overused. This paper suggests that the policy makers intensify the reform of supply ̄side policy toolsꎬ mod ̄ erately increase the use of demand ̄side policy toolsꎬ keep a balance among the internal elements of environmental policy tools and promote the construction of an " integrated" service platform for adolescent health.
