Abstract:As an important part of public policy and a core of policy system, science and technology policy plays a crucial role in the development of economy and society as well as the enhancement of national comprehensive competitiveness. To improve the quality of science and technology policy, we need to prevent the fragmentation, disconnection and conflict in science and technology management. From the perspective of policy process, the fragmentation of science and technology policy is mainly manifested on the policymakers, the content and the value orientation of policies as well as policy tools, implementation deviation, evaluation standards and policy continuity. At present, China"s science and technology policies have various degrees of fragmentation, including the short board phenomenon in policy content, poor cooperation among policymakers, multiple orientation for the objectives of policy instruments, lack of coordination among implementing subjects, deviation of policy implementation, inconsistent evaluation standards, lack of continuity and so on so forth. To effectively solve the fragmentation of science and technology policy, we should set up a governance mechanism which is scientific, targeted and operable from the aspects of the value orientation, the policymaker, the implementation, the evaluation and the conclusion of the science and technology policy.
