混合式结构多供应链竞争研究

Research on multi-supply chains competition of hybrid structure

基于Stackelberg博弈理论,结合市场中消费者的消费行为特征,建立了具有潜在型客户和分析型客户的多供应链价格竞争模型.讨论了该模型在线性需求函数下混合式供应链的均衡解.研究发现,当每条供应链市场份额小于平均市场份额时,适当的竞争有利于供应链利润的增加,但随着供应链竞争强度的增加,供应链的利润在总体上呈减小趋势.同时考虑每条供应链在均分市场的情况下,可替代产品竞争的激烈程度将直接影响到供应链的均衡结构,通过分析得到,在市场竞争强度很大时,分散式结构优于集中式结构,且在一定条件下混合式供应链占优的结论.

Based on the Stackelberg game theory a multi-supply chain competition model with potential and analytical customers is constructed considering consumer behaviors in the market. Equilibrium solution of hy- brid supply chains is discussed under the linear demand function. The results show that, when each market share of supply chains is less than the average market share, the appropriate competition may result in an increase in the profit of supply chain. But, the total profit will decrease as the competition intensity increases. Meanwhile, considering the effect of the competition intensity of alternative products on the equilibrium structure of the supply chains under the same market shares, the paper gets the conclusions that the distributed structure of the supply chain will always be better than the centralized structure when the competition is fierce, and that the condition of the hybrid structure is the better structure.
