Abstract:As one of the most important tools for national strategic guidance and resource allocation, the national S&T (science and technology) tasks are becoming the core supporting force for future industrial and S&T competition. Under the increasingly competitive environment, it is important for the national S&T tasks to be incorporated into the fixed decision-making mechanisms as to maintain the long-lasting supporting function in the sustainable global competition of S&T and economy. This study summarized the concept and the evolution of the "public governance" and proposed the decision-making framework for the national S&T tasks. The decision-making framework mainly consists the following parts, which are the construction of the legislation and supervision system for the S&T decision-making system, incorporating the appeals of the S&T bodies into the decision-making mechanism, the democratic top decision-making by combination of the appeals from much more S&T bodies and the construction of long-lasting feedback and the synergy among the S&T bodies. This study can provide theoretical reference for the reform of national S&T system and the management of national S&T projects.
