政府干预与契约机制对绿色供应链的演化影响

The Evolutionary Impact of Government Intervention and Contractual Mechanisms on Green Supply Chains

摘要: 本文旨在探讨在政府监督与宣传政策背景下，不同契约机制对绿色供应链主体行为及绩效的影响。主要研究以制造商和零售商构成的二级供应链，通过在NetLogo平台上构建绿色供应链多主体仿真模型(ABM)，模拟无成本分担契约与成本分担契约两种模式下的主体行为演化。研究发现：1) 成本共担契约能有效降低制造商绿色研发成本压力，当成本分担系数为0.4时，供应链经济效益与环境效益达到最优平衡；2) 政府适度监督与强宣传政策组合可显著提升制造商绿色转型意愿，但过度监督会抑制市场活力；3) 契约机制与政策工具需协同设计，以实现绿色供应链的可持续发展。研究为政策制定者设计组合政策工具以及企业间制定协同合作契约提供了理论依据。

Abstract: This paper aims to explore the impact of different contract mechanisms on the behavior and performance of green supply chain entities in the background of government supervision and publicity policies. This paper mainly studies the two-level supply chain composed of manufacturers and retailers. By constructing a multi-agent simulation model (ABM) of the green supply chain on the NetLogo platform, the evolution of agent behavior under two modes of non-cost-sharing contract and cost-sharing contract is simulated. The study found that: 1) The cost-sharing contract can effectively reduce the pressure of manufacturers’ green R&D costs. When the cost-sharing coefficient is 0.4, the economic and environmental benefits of the supply chain reach the optimal balance; 2) The combination of moderate government supervision and strong propaganda policy can significantly enhance the green transformation willingness of manufacturers, but excessive supervision will inhibit market vitality; 3) Contract mechanisms and policy tools need to be collaboratively designed to achieve the sustainable development of the green supply chain. The research provides a theoretical basis for policymakers to design combined policy tools and formulate collaborative cooperation contracts among enterprises.
