基于博弈模型的供应链企业合作创新

Supply Chain Enterprise Cooperative Innovation Based on Game Model

为适应互联网经济变革的常态化,供应链企业需要创新合作机制以适应经济发展。针对由生产商与销售商构成的二级供应链系统,分别利用动态博弈和合作博弈两种模型推演出创新度与利润的均衡解,发现企业合作时创新度更强,获得的利润更多。在企业合作前提下探讨创新度、创新利润和产量之间的关系,发现创新遵循规模经济理论,创新利润随产品生命周期呈曲线变化。最后,针对产品初创期、成长期、成熟期和衰退期各阶段,为合作企业创新提出相应建议。

In order to adapt the normalization of the Internet economy changes,supply chain enterprises need to innovate cooperation mechanism to fit the economic development. For the two echelon supply chain system of producers and sellers,based on the dynamic game and the cooperative game models,the equilibrium solutions of innovation degree and maximum profit were derived. The results show that both the innovation degree and the profit under the enterprise cooperation pattern are more than those under enterprise non-cooperation pattern. Based on the conclusion,the paper discusses the relationship between innovation degree,innovation profit and output. The study shows that innovation follows the theory of scale economy,and we give the innovation profit curve in product life cycle. Finally,for the problem of cooperative innovation during the different stages of the product life cycle,we put forward some suggestions for cooperative enterprises during product's early stage,growth stage,mature period and recession period.
