Logistics services and product prices are two factors that influence consumers’ buying behavior. In recent years, research on decision and coordination of competing supply chains has attracted growing attention. However, the research of competing supply chains with substitutable products under logistics services and product prices has not been studied in the literature. We consider four decision variables, the manufacturers’ wholesale price, the distributors’ wholesale price, the retailer price and the logistics service level. The competition in product and pricing decisions of the supply chains are discussed based on centralized and decentralized channel structures. And then, effect of product substitutability upon decisions and coordination of the supply chains is analyzed. Finally, A numerical example illustrates the findings of the model are summarized for centralized, decentralized, and coordinated scenarios. The results from the analysis show that gross profit of supply chain under decentralized channel structure increases with the increasing product substitutability, but declines under centralized channel structure. The value region of benefit-sharing proportions under the centralized channel structure also shrinks, that is, the scope of bargaining that companies can make for their profit in the collaborations gets smaller and smaller when product substitutability increases.

物流服务和产品价格是影响消费者购买行为的两个因素。近年来，关于竞争性供应链的决策和协调的研究引起了越来越多的关注。然而，文献中还没有研究在物流服务和产品价格下具有可替代产品的竞争供应链的研究。我们考虑四个决策变量，即制造商的批发价格，分销商的批发价格，零售商的价格和物流服务水平。基于集中式和分散式渠道结构，讨论了供应链的产品竞争和定价决策。然后，分析了产品可替代性对供应链决策和协调的影响。最后，数值示例说明了针对集中式，分散式和协调式方案总结的模型结果。分析结果表明，分散渠道结构下的供应链毛利润随着产品可替代性的提高而增加，而在集中渠道结构下则下降。在集中化渠道结构下，利益共享比例的价值区域也缩小了，也就是说，随着产品可替代性的提高，公司可以在合作中获利的讨价还价的范围越来越小。但在集中式渠道结构下会下降。在集中化渠道结构下，利益共享比例的价值区域也缩小了，也就是说，随着产品可替代性的提高，公司可以在合作中获利的讨价还价范围变得越来越小。但在集中式渠道结构下会下降。在集中化渠道结构下，利益共享比例的价值区域也缩小了，也就是说，随着产品可替代性的提高，公司可以在合作中获利的讨价还价的范围越来越小。
