Abstract: Utilizing the innovative capacity of enterprises and the organizational role of governments can greatly enhance China’s efforts in achieving breakthroughs in key core technologies. A number of Public sectors in the United States have adopted the public-private Partnership (PPP) model in major scientific and technological projects, especially the most famous model of National Aeronautics and Space Administration(NASA), which has greatly improved the development efficiency of major space technologies and promoted industrial development. This paper takes the Space Technology Mission Directorate (STMD) of NASA as the research object, analyzes the mechanism of the organization’s technology investment direction and the operation mechanism of the public-private partnership technology development mode, and summarizes the characteristics of the NASA public-private partnership technology development mode led by STMD，including: (1) Multi-thread technology development task selection mode (2) task decision and plan execution module linkage mode (3) Differentiated public-private partnership technology development plan setting, Finally, the paper puts forward the suggestions to improve the cooperation from three aspects: strengthening the strategic layout of government-enterprise cooperation technology research, optimizing the selection mode of major scientific and technological tasks of government departments, and establishing differentiated combination of government-enterprise technology research plans.
