针对链与链市场地位不平等情形,构建了2条具有先后决策顺序的主从竞争供应链模型,分析了不同纵向控制结构组合下主链先决策与从链后决策的供应链绩效和博弈均衡。研究发现,在主从链基于价格竞争条件下,2条链的博弈均衡为中心化控制结构。当2条链的市场规模悬殊时,随着竞争强度的增加,主链的利润逐渐降低,从链的利润逐渐增加。
Considering the situation that the market influence of the competitive supply chain is not equal,this paper builds a model with two supply chains of a decision sequence to investigate the supply performances and game equilibrium of different control structure combinations under the situation of chain to chain competition.We found the Nash equilibrium only occurs when the leader and the follower chain both choose centralized structure.When there is wide gap of market scale between the two supply chains,with the intensity of competition increases,the profits of the leader chain will decline gradually while the follow chain rise gradually.
