【摘要】：为了探讨知识产权保护力度对供应链网络中各个制造商及网络其他成员的影响,本文建立了考虑研发投入溢出效应的供应链网络均衡模型,其中供应链网络由多个制造商、零售商和需求市场构成,制造商为获得更大的利润会进行研发投入,技术水平的提升会降低生产产品的单位成本,但会产生研发的溢出效应。利用均衡理论和变分不等式分别得到考虑研发投入溢出效应的各个制造商、零售商和需求市场的均衡条件,并得到整个供应链网络的均衡条件。最后给出求解均衡条件的算法和数值算例,分析了制造商的研发投入所产生的溢出效应对供应链网络各成员决策的影响。数值结果表明,不论是研发水平对称还是不对称的情形,随着创新溢出效应的增强,制造商的利益都会受损,且对创新水平高的企业尤其明显。
[Abstract]:In order to explore the impact of intellectual property protection on the manufacturers and other members of the supply chain network, a supply chain network equilibrium model considering the spillover effect of R & D inputs is established, in which the supply chain network is composed of multiple manufacturers. Retailers and demand market structure manufacturers will invest in R & D in order to get more profit. The improvement of technology level will reduce the unit cost of production products but will have the spillover effect of R & D. By using equilibrium theory and variational inequality, the equilibrium conditions of manufacturers, retailers and demand markets considering the spillover effect of R & D inputs are obtained, respectively, and the equilibrium conditions of the entire supply chain network are obtained. Finally, an algorithm for solving equilibrium conditions and numerical examples are given, and the effect of spillover effect of manufacturer's R & D investment on the decision making of members of supply chain network is analyzed. The numerical results show that with the enhancement of innovation spillover effect, manufacturers' interests will be damaged, especially for firms with high innovation level, regardless of whether R & D level is symmetric or asymmetric.
