摘　　要：论文分析一个三阶段研发博弈模型,在模型中溢出系数如果由企业内生化自主决定,那么,溢出系数只存在角点解。论文考虑了不合作研发与合作研发古诺竞争、不合作研发与合作研发伯川德竞争四种情形,发现无论产品差分如何,在古诺竞争和伯川德竞争情形下,合作研发效率总是高于不合作研发;在产品互补或替代条件下,当不合作研发时伯川德竞争效率高于古诺竞争效率,而合作研发时古诺竞争效率高于伯川德竞争效率,当产品独立时,无论是否合作研发,古诺竞争效率等于伯川德竞争效率。The paper analyses a three-stage model in which the spillover is depend on the enterprise's endogenous,then the ration of spillover only have angular point.We analyse the Cournot competition and Bertrand competition under the circumstances of cooperative and noncooperative R&D.The main conclusions include:(1) the efficiency of cooperative R&D is always higher than noncooperative R&D,no matter of the product differentiated and competition fashion;(2) if the product is complementary or substituted,the efficiency of Bertrand competition is higher than Cournot's under the noncooperative R&D,and vice versa;(3) if the product is independent,the efficiency of Cournot competition and Bertrand competition is the same.
