【摘要】：研究双渠道供应链中生产商负责的网上直销渠道对零售商负责的传统零售渠道的信息服务搭便车行为。假定产品需求随机且依赖于零售商信息服务水平,利用条件风险值准则和均衡分析方法建立了生产商与零售商均为风险厌恶者时双渠道供应链的集中式决策模型和分散式决策模型,利用合同理论给出了协调供应链的回购加信息服务补贴契约,利用数值仿真方法验证了模型的合理性和协调契约的有效性。研究表明,增加直销渠道对供应链而言是把"双刃剑",既可吸引潜在需求,也应避免需求由零售渠道向直销渠道的大规模转移;直销渠道的信息服务搭便车行为有利于供应链各方;决策者越厌恶风险,其订货量越低,此时生产商、零售商和供应链的利润都将下降;当风险厌恶因子等于1时,决策者风险厌恶时双渠道供应链的决策与决策者风险中性时一致。
[Abstract]:This paper studies the hitchhiker behavior of the online direct selling channel in the double channel supply chain which is responsible for the traditional retail channel. Assuming that product demand is random and dependent on the retailer's level of information services, Based on the conditional risk value criterion and equilibrium analysis method, a centralized decision model and a decentralized decision model for a supply chain with both producers and retailers as risk averse are established. The repurchase and information service subsidy contract of the coordinated supply chain is given by using the contract theory. The rationality of the model and the validity of the coordination contract are verified by the numerical simulation method. The research shows that increasing direct marketing channel is a double-edged sword for supply chain, which can attract potential demand and avoid large-scale transfer of demand from retail channel to direct marketing channel. The more risk-averse the decision maker, the lower the order quantity, and the lower the profit of producer, retailer and supply chain; when the risk aversion factor is equal to 1, When decision-makers are risk-averse, the decision of two-channel supply chain is consistent with the risk-neutral decision makers.
