摘　　要：通过整合自主研发与协作研发两种形式可以建立企业R&D网络化动态博弈模型与分析企业的R&D投资决策。研究发现企业在自主研发和单个协作组织中的投资随着协作程度和外生系数的增加而增加,随着协作规模的增加而减少。最后分析了各相关因素对企业利润和社会福利的影响程度,发现在生产企业相对集中的行业中,密集的协作网络为企业带来更多的期望收益,而在生产企业相对分散的行业中,自主研发对企业来说是最优决策模式。We can develop a dynamic model of corporation R＆D network-based game and analyze firms＇ R＆D investment decisions by integrating independent research and cooperative research these two forms.Research reveals that a firm＇s investment in the independent projects as well as in each of the joint projects increases with collaborative degree and exogenous coefficient,and decreases with collaborative size.Ultimately,after comparing the affect of correlative factors to firm＇s profit and social welfare,we find out in concentrated markets dense networks can bring more profit while in markets with many firms pure in-house research is optimal for firms.
