技术创新型企业研发投资的三阶段博弈——基于吸收能力的观点

将Lars Wiethaus模型中的吸收能力提出了简化表达,研究竞争企业在吸收能力、研发水平、研发投资之间的关系.提出了三阶段博弈模型,首先,企业选择吸收能力;然后,企业决定R&D支出;最后.企业进行古诺特产量竞争.采用逆向归纳法求解.通过理论研究和数值模拟得出:研发不舍作时,单个企业的最优吸收能力与对手企业的技术外溢水平有关;吸收能力较小时,企业在研发投入上陷入了"囚徒困境"问题;研发合作会内部化企业的"搭便车"行为;研发合作时的研发成果、利润都要比不合作时要高.

Three Stage Game of Technical Innovation Firms --Based on the Conception of Absorptive Capacity

A simple expression of absorptive capacity in the model of Lars Wiethaus is proposed.we provide a three-stage game model,in which the choice of optimal absorptive capacity is made in its first stage,the firms' R&D budgets and output levels are chosen in the game's second and third stages respectively,to explore the relationship between competitive firms on R&D approaches,R&D investment and absorptive capacity.We use backward induction to get the sub-game perfect Nash equilibrium.Through the analysis of equi...
