| 摘 要： | 放松了经典Cournot模型中市场容量不变的假设,构建了双寡头企业R&D动态竞争的Cournot模型,研究了双寡头在R&D投入和产量决策两个阶段完全竞争与完全合作情形下的均衡结果.结果表明增加新增市场容量可以提高企业的最佳R&D投入水平和均衡利润,并且可以维持更长久的博弈周期.结果还表明动态R&D竞争模型是对传统模型的进一步拓展,能适用于更广泛、更实际的竞争情形.

| Abstract: | By modified the hypothesis that the market capacity was fixedness in the traditional Cournot model;the duopoly's dynamic R&D competition model is established.The paper analyzed the equilibrium results of noncooperation and cooperation during the R&D stage and output stage in one competition period.The results show that increment of new market capacity can increases the optimal R&D level and profits,and also can create more competition periods.The dynamic R&D competition model is extension to the traditional... |
