公平偏好信息非对称下E-闭环供应链协调机制设计

Coordination Mechanism Designing for E-commerce Closed-loop Supply Chains with Asymmetric Information of Fairness Concerns

考虑电商平台公平偏好信息非对称,建立制造商主导的E-闭环供应链回收与定价决策模型,采用逆向归纳法和对比分析法研究公平偏好对E-闭环供应链各方决策的影响,并设计收益共享-成本共担契约进行协调.研究表明,无论电商平台公平偏好信息是否对称,批发价格契约都不能协调E-闭环供应链,但只要制造商考虑电商平台公平偏好进行决策,就有利于降低零售价格,提高服务水平和废旧品回收率.无论电商平台公平偏好信息是否对称,收益共享-成本共担契约总能优化各方决策,提高废旧品回收率,实现E-闭环供应链协调,以及帕累托改进各方利润.此外,电商平台公平偏好会使收益分享比例范围变大,更容易实现E-闭环供应链协调.

Considering the asymmetry of fairness-concern information on e-commerce platforms,a recycling and pricing decision model in a manufacturer-dominated e-commerce closed-loop supply chain is established.The impact of fairness concerns on the decisions of all parties in an e-commerce closed-loop supply chain is studied by reverse induction and comparative analysis,and the contract with revenue sharing and cost sharing is designed to coordinate the e-commerce closed-loop supply chain.Results show that whether fairness preference information of e-commerce platforms is symmetric or not,the wholesale price contract cannot coordinate the e-commerce closed-loop supply chain,however,as long as the manufacturer considers fairness concerns of the e-commerce platform for decision-making,it is beneficial to reduce retail prices,improve service levels and waste recycling rates;Whether the fairness preference information of the e-commerce platform is symmetric or not,the contract with revenue sharing and cost sharing can always optimize the decisions of all parties,improve waste recycling rates,achieve coordination of an e-commerce closed-loop supply chain,and improve profits of all parties in terms of Pareto optimization.Moreover,the fairness concerns of the e-commerce platform can increase the range of revenue sharing ratios,making it easier to achieve coordination of an e-commerce closed-loop supply chain.
