Multidimensional R&D-price level game model analysis of duopoly group

Abstract

For meeting the need of development of enterprises integration and the trend of collaborative technological innovation, this paper establishes two dimensional game models of R&D cooperation and noncooperation, according to the situation that there are two duopoly groups with two types of products. Based on the conditions of knowledge spillover and absorptive capacity, specifically analyze the impacts of each case of the knowledge spillover, the absorptive capacity of R&D investment, profits and product price level. Game analysis and numerical simulation results, considering from the level of R&D investment and equilibrium price point view, show that cooperation case could gain more profits than semi cooperation and competition case, which also precisely validate that collaborative innovation will be achieved when the cluster enterprises achieve maximum profit; and It is beneficial for R&D and pricing of oligopoly.
