The cooperative R&D based on research joint venture and enterprise R&D decision with spillover

This paper studies the cooperative R&D problems based on RJV (Research Joint Venture). The paper extends the framework of Wang model, and sets up a two-stage game model of cooperation research. The paper solves the game model and compares the effect of RJV cooperation research and general cooperation research, which would provide basis for the cooperative R&D decision option. The result shows that, without the considerations about the free-ride manufactures, RJV cooperative R&D is applicable when the technology spillover effect is relatively small, but if it is relatively large, the R&D cartel is applicable. If the free-ride manufactures are considered, the RJV cooperative R&D is applicable.
