摘　　要：在存在研发成果溢出与研发投资溢出时,建立了以产量竞争的古诺双寡头两阶段博弈模型。在四种不同的R&D策略下,比较了两种溢出方式下企业的R&D水平。研究表明:当存在研发成果溢出时,与存在研发投资溢出相比,企业有较高的R&D水平;当存在研发投资溢出时,每个企业的R&D水平随着溢出水平的提高而下降;在没有溢出效应时两个模型是等价的。从促进技术进步的角度来看,无论是存在研发成果溢出还是存在研发投资溢出,在四种策略中,研究联合体策略优于其他任何一种策略。This paper introduces a two-stage game model in the Cournot duopoly competition based on the output competition. The paper compares the R＆D level of the firms under the output and investment spillover in the context of the four R＆D strategies. The research re- veals that the firms with the output spillover have higher R＆D level than those with invest- ment spillover. R＆D level of the firms decreases when spillover level rises. The two models are equivalent in the absence of spillover effects. The research joint venture strategy proves the best among the four strategies whether under output spillover or investment spillover from the perspective of technology progress.
