Efficiency formation of National Innovation System: A project view

The purpose of this paper is to discuss the mechanism of efficiency formation of NIS. In view of project, NIS could be regarded as an innovation projects portfolio. Using methodology of system analysis, the result of this paper is: There are three hierarchies including element hierarchy, project hierarchy and system hierarchy; three efficiency variables named as element efficiency, integration efficiency and structure efficiency and there are three key processes for each variable. Based on this framework, the conclusion is to improve the efficiency of integration and structure of NIS for China.
