[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.
