| 摘 要： | 构建了一个异质双寡头R&D竞合模型,根据R&D投入与产量决策阶段的合作类型,研究了双寡头分别在利润最大化及社会福利最大化条件下四种竞合模式的最优技术溢出水平。讨论了每种模式下最优技术溢出对均衡产量、利润、消费者剩余的影响。结果表明半合作和完全合作模式下最优技术溢出为1,而完全不合作模式下最优技术溢出可以不为1。

| Abstract: | A differentiated duopolistic model is considered where the two firms both conduct R&D activities.The optimal technical spillovers for R&D under four cases is studied which three different kinds of cooperation modals about maxim of firms' profits and one about maxim of social welfare.And the effects of change of optimal technical spillovers on output,profits,consumer surplus are analyzed under every case.And results show that the optimal technical spillover is one when cooperation exists in R&D stage and it ... |
