摘　　要：运用非线性动力系统理论建立了异质双寡头R&D竞争基于有限理性条件下的动态模型,分析了该系统的均衡点及其稳定性,并用Matlab数值模拟了不同市场参数条件下的系统动态演化状况。模拟结果表明R&D投入调整速度过快会使系统陷入混沌;企业可以通过增加产品特色来提高自身竞争优势;企业在重复博弈过程中技术溢出水平会同方向调整,直至均衡。In this paper, a dynamic R＆D competition model of heterogeneous duopoly is estab- lished, and this dynamic system＇s equilibrium points and their stability are analyzed. System sta tus under different parameter values are showed by employing Matlab numerical simulation. The simulation results shows that exaggerated adjusting speed of R＆D investment input would cause the appearance of complicated dynamics phenomena, such as bifurcations and chaos. It also shows that companies can improve their competitive advantage by increasing product differentiation. Companies will adjust their technology spillovers in the same direction until they reached the equilibrium.
