Analysis of cooperative technological innovation strategy

This article focuses on the cooperative innovation under oligopoly with game theory approach. The effects of cooperative innovation are addressed. First, we argue that the total innovation investment of cooperators is more than that of an individual firm without cooperation. Second, the number of cooperative partners has different effects on firms’ innovative investment. Cooperative innovation investment decreases in both the number of cooperators and the total number of firms in the industry, while the innovation investment of non-cooperators increases. Finally, the optimal number of cooperators is initially highlighted in theory. The optimal number of firms in cooperation is achieved for cooperators, non-cooperators and social welfare, respectively.
