Effect of Network Structure and Preference Difference on Knowledge Transfer in Inter-organizational R&D Project

An evolutionary game model of knowledge transfer in inter-organizational R&D projects was established, and its local stability was analyzed. Then, the complex network and preference theory are introduced to establish the game model of knowledge transfer in the cooperation network of inter-organizational R&D projects under the condition of preference differences and different network structures. Finally, the influence of key factors, preference difference and network structures on strategy selection is analyzed. The results show that the cost coefficient has a negative correlation with the level of knowledge transfer, while the increase of other coefficients promote knowledge transfer behavior. The increase of altruistic preference degree and the proportion of altruistic preference agents can promote knowledge transfer behavior, while the increase of competitive preference degree and the proportion of competitive preference agents can inhibit knowledge transfer behavior. Moreover, the level of knowledge transfer is higher in the scale-free network than in the small-world network in most cases. However, punishment plays a greater role in the small-world network.
