在本研究中，我们考虑基于博弈论的框架来模拟具有价格依赖随机需求的供应链中的权力，并研究权力结构（占主导地位的零售商、占主导地位的制造商或均衡的权力）和需求模型（预期需求和需求冲击）如何影响供应链效率、成员利润和消费者剩余。我们分析了这个框架中的所有问题，并描述了它们的均衡结果。相比之下，我们证明，除了电力制造商可能在具有等弹性需求和附加冲击的供应链中遭受损失外，企业通常从其电力中受益。平衡的权力结构通常有利于整个供应链，但在需求等弹性和附加冲击的供应链中，这种结构可能表现不佳。权力结构和需求模型对消费者的影响与对供应链效率的影响大致相同。换句话说，消费者往往更喜欢一个平衡的权力结构，因此不会从电力零售商那里获利。此外，我们发现零售价格在决定供应链效率和消费者剩余方面起着关键作用。具体来说，零售价格越低，供应链效率越高，消费者剩余越高。相比之下，服务水平对两者的影响都不那么显著。
In this study, we consider a game theory based framework to model power in a supply chain with price-dependent stochastic demand and to investigate how power structures (dominant retailer, dominant manufacturer, or balanced power) and demand models (expected demand and demand shock) affect supply chain efficiency, members’ profits, and consumer surplus. We analyze all of the problems in this framework and characterize their equilibrium outcomes. In comparison, we demonstrate that a firm often benefits from its power except that a power manufacturer might suffer in a supply chain with isoelastic demand and additive shock. A balanced power structure is often conducive to the whole supply chain, but this structure might not perform very well in a supply chain with isoelastic demand and additive shock. Power structures and demand models act on consumers in much the same manner that they do on supply chain efficiency. In other words, consumers often prefer a balanced power structure and thereby do not profit from power retailers. Additionally, we find that the retail price can play a pivotal role in determining supply chain efficiency and consumer surplus. Specifically, the lower the retail price, the higher the supply chain efficiency and consumer surplus. In contrast, the service level has a less preeminent influence on both of them.
