【摘要】：知识产权保护力度不够导致了现在社会上抄袭、模仿现象严重,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、零售商均衡条件,并推导出整个供应链网络模型的均衡条件。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。本文的主要研究内容和创新点如下:(1)研究了考虑溢出效应的制造商研发投入供应链网络静态均衡问题,建立了包含多个制造商、零售商和消费市场的供应链网络均衡模型,利用变分不等式描述了各制造商、各零售商的最优决策,推导出整个供应链网络的均衡条件。结合数值算例的结果,分析了溢出效应对制造商研发投入和整个供应链均衡的影响,发现创新的溢出会降低企业特别是高创新水平的企业的研发积极性和利润。(2)研究了考虑溢出效应的制造商研发投入供应链网络动态均衡问题,建立了多个制造商、零售商的两层供应链网络动态均衡问题,利用微分变分不等式描述了各制造商和各零售商的最优决策,得到整个供应链网络的动态均衡条件。通过数值算例,分析了在市场条件动态变化条件下溢出效应对制造商研发投入的影响,发现市场需求的不断增加和创新溢出的降低会提高企业的研发积极性。
[Abstract]:In order to explore the impact of intellectual property protection on the manufacturers and other members of the supply chain network, the lack of intellectual property protection has led to plagiarism and imitation phenomenon. In this paper, a supply chain network equilibrium model considering the spillover effect of R & D input is established, in which the supply chain network is composed of multiple manufacturers, retailers and demand markets, and manufacturers will invest in R & D in order to obtain greater profits. The improvement of technology level will reduce the unit cost of the product, but will produce the spillover effect of R & D. By using equilibrium theory and variational inequality, each manufacturer considering the spillover effect of R & D investment can be obtained. The retailer equilibrium condition and the equilibrium condition of the whole supply chain network model are derived. Finally, the algorithm and numerical examples are given to solve the equilibrium condition. This paper analyzes the spillover effect of manufacturer's R & D investment on the decision making of members of supply chain network. The main contents and innovations of this paper are as follows: 1). The static equilibrium problem of manufacturer R & D input supply chain network considering spillover effect is studied. A supply chain network equilibrium model including multiple manufacturers, retailers and consumer markets is established, and the optimal decision of each manufacturer and retailer is described by using variational inequalities. The equilibrium conditions of the whole supply chain network are deduced, and the effects of spillover effect on the manufacturer's R & D investment and the whole supply chain equilibrium are analyzed. It is found that innovation spillover will reduce the R & D enthusiasm and profit of firms, especially those with high innovation level.) the dynamic equilibrium of R & D input supply chain network of manufacturers considering spillover effect is studied. The dynamic equilibrium problem of multi-manufacturer and retailer two-layer supply chain network is established, and the optimal decision of each manufacturer and retailer is described by using differential variational inequality. The dynamic equilibrium conditions of the whole supply chain network are obtained, and the effects of spillover effect on the R & D investment of manufacturers are analyzed by numerical examples. It is found that the continuous increase of market demand and the decrease of innovation spillover will increase the R & D enthusiasm of enterprises.
