研究与开发（R＆D）活动是企业申请专利所需知识的源泉，因此R＆D投资行为将决定企业在专利竞赛中的地位。以专利竞赛为背景。按照企业R＆D投资行为的特征，依据马尔科夫链（Markov Chain）的基本思想建立了专利竞赛中企业R＆D投资决策模型；并在此基础上得出结论：（1）专利竞赛中无论是领先企业还是落后企业都可以通过采取适当的R＆D投资策略而获得R＆D活动的成功；（2）无论企业本期R＆D的投资决策如何，只要下一期R＆D投资决策得当，也可以最终获得R＆D活动的成功。研究剔除了初始R＆D活动状态对专利竞赛结果的影响，并将专利竞赛过程扩展到有限可列个时期，拓展了专利竞赛理论研究的领域。研究对我国企业技术追赶过程中R＆D投资策略的制定具有一定的指导价值。

Since research and development （R＆D） is a main source of knowledge for patenting, the decision-making of R＆D investments will play a decisive role in patent race. This paper, based on the characters of R＆D investments, establishes a decision-making model of R＆D investment from the Markov chain perspective. And we get the conclusions： a） R＆D activities can be successful if the firm, whether the leader or the laggard in the patent race, choosing proper R＆D investment; and b） eventually, through a proper R＆D investment, firm can be succeed in R＆D activities, whether it＇s R＆D activity is successful or not for current period. This research has extended the extant researches in the field of patent race by eliminating the influence of initial R＆D condition and expanding patent race to infinite countable periods. Moreover, the findings in this paper provide guide lines for decision-making of R＆D investment during the technological catching-up process for Chinese firms.
