摘要： 针对同质企业替代研发的技术外溢与企业创新合作关系进行研究，拓展了企业研发合作领域中经典的AJ模型，针对不同的竞争和合作关系构建了无成本共享、成本共享、信息共享情况下的期望利润模型，并用逆向归纳法进行了求解.通过对比各个状态下纳什均衡的研发投入与产量，得出研发支出随着技术外溢的溢出率增加而降低和产量随着技术外溢的溢出率增加而有所增长的结论，证明了R＆D行为在同质企业替代研发中产生的溢出效应对企业之间的合作起到积极的影响.

关键词: 同质企业, 替代研发, 纳什均衡, 溢出效应

Abstract: The technology spillover of alternative development in homogeneous enterprises and the partnership of enterprise innovation were studied， and the classic AJ model in the field of enterprise R&D cooperation was expanded. Based on the different relationships of competition and cooperation， the expected profit models in terms of noncost sharing， cost sharing and information sharing were constructed respectively， and the solution was given by using backward induction. By comparing R&D investment and production of Nash equilibrium in various states， the conclusion was drawn that R&D expenditure decreased and production grew with the increase of technology spillover rate. The results showed that the spillover effect generated by R&D behaviors in the alternative development of homogenous industries exerts a positive impact on the cooperation among enterprises.

Key words: homogereous enterprise, alternative development, Nash equilibrium, spillover
