摘　　要：界定出寡头市场上潜在技术主导厂商的R&D投资效率边界,分析了不同R&D投资效率条件下厂商的创新动机.研究结果表明:当潜在技术主导厂商具有高效R&D投资率时,网络外部性的增大会增进其R&D动机,而兼容性和用户学习成本的增大会削弱其R&D动机,当潜在技术主导厂商具有低效R&D投资率时,与上述情况相反.This paper originally defined the boundary of efficiency of R＆D investment （ERI） of the poten tialtechnologicalleader＇s, and analyzed its incentive to innovate with various ERI. The study shows that, when the leader firm＇s ERI is ＂high＂, its incentive of R＆D will increase in network externality but decrease in compatibility and learning cost. When its ERI is ＂low＂, it gets the opposite conclusion.

关 键 词：网络外部性 R&D投资 创新动机
