摘要
本文考虑了一个双寡头的微分博弈模型,其中两家企业在技术溢出和技术更新的环境下从事研发活动,每家企业在研发阶段进行研发竞争或合作,但在产出阶段进行竞争。通过比较研发竞争和研发合作下的企业瞬时收益,本文分析了技术溢出和技术更新是如何影响企业研发战略的。进一步,本文还讨论了企业研发战略的演化路径。
A duopolistic differential game model which two firms conduct RD activity with technology spillover and technology update is considered.Each firm in the model competes or cooperates with each other in a RD stage but compete in an output stage.How technology spillover and technology update affect firm＇s RD strategy is studied by comparing transient profit between RD competition with RD cooperation,and how RD strategy of firms changeing over time is discussed.
