The game and synergy of cooperative R&D under bilateral controlled spillover

Based on the points of view that the spillover is decided by the similarity of technical path, we construct R&D cooperation game under the bilateral-controlled technology spillover, and compare the game features of non-cooperative R&D with that of cooperative R&D. The study shows that in non-cooperative R&D, the closer the technology is, the less the firms are willing to invest; the firm with higher R&D cost prefers higher spillovers; the socially optimal distance between technologies is higher than the profitable distance.
