激励绿色供应链企业开展生态设计的机制决策

绿色供应链双重边际化效应和绿色创新的双重外部性特征需要协调机制来激励成员企业开展生态设计.为此,用博弈模型构建了以供应商为领导者的成本分担机制和基于信息共享的利益分配机制,进而研究其对生态设计努力和供应链各方收益的影响.结果显示供应商主导的成本分担机制激励效果甚微,而增加信息共享的程度可以极大地提高供应链企业利益分配比例和生态设计努力水平.此外,核心企业增加绿色信息的共享能显著激发供应链非核心企业的绿色研发投入,为改善绿色供应链的环境效益发挥引领创新和协调合作的积极作用.本研究从生态设计视角为实现绿色供应链整体绩效优化,促进产业绿色转型提供了理论建议和决策支持.

Mechanism decisions to encourage product eco-design implemented by green supply chain enterprises

Because of the widespread double marginalized phenomenon in green supply chain and dual externality of product green innovation, it needs coordination mechanisms to motivate member cooperation to make investment in eco-design. In view of it, this article formulated supplier-dominated cost sharing mechanism and revenue distribution mechanism based on information sharing using game models, and then investigated their impacts on the eco-design effort and supply chain benefits. Results show that the cost sharing mechanism leaded by suppliers has little incentive effects, however, increasing the level of shared information can greatly improve the revenue distribution proportion and eco-design effort of supply chain members. Furthermore, the green R&D investments of non-core members can be significantly stimulated by more green information shared by core enterprises, which plays a positive role in improving the environmental benefits of green supply chain, in other words, leading innovation and coordinating partnership. From the perspective of eco-design, this study provided the theoretical suggestion and decision support for optimizing the green supply chain performance and promoting industrial green transformation.
