Abstract
ABSTRACT This study constructs an oligopoly model considering generic technology R&D, analyzes the market equilibrium results under R&D cooperation and non-cooperation, explores the impacts of technology spillover, cost difference, and firm’s bargaining power, and compares the boundary conditions between R&D cooperation and non-cooperation. The results show that when the degree of technology spillover is small, the R&D firm conducts drastic R&D, resulting in a complete monopoly. The market structure and equilibrium results are influenced by the degree of technology spillover, cost difference, bargaining power, and the number of following firms. Cooperation in R&D can be considered as a Nash equilibrium in certain cases. Compared with R&D non-cooperation, R&D cooperation can lead to higher profits for firms. When the degree of technology spillover is large and the number of following firms is small, R&D cooperation yields greater consumer surplus and social welfare.
