针对单制造商和单零售商组成的供应链,考虑供应链碳减排技术投资与否两种情形,构建了集中式决策、分散式决策和供应链成员协同决策的博弈模型,探讨了消费者碳足迹敏感系数、碳限额及碳减排成本系数对供应链成员最优决策及减排效果的影响。研究表明,碳交易价格与碳限额呈线性关系时,供应链及制造商的利润与碳限额并不是线性递增的关系,政府合理的制定碳限额能够促使供应链企业有效减少碳排放;当消费者支付意愿依赖于产品碳足迹时,企业可以通过投资碳减排技术在减少碳排放量的同时获取更大的利润,实现环境与经济的协调发展。制造商和零售商通过渠道协作共同决策碳减排水平时,供应链碳排放总量比分散决策情形下明显减少。
Aiming at the supply chain composed of single manufacturer and single retailer, the game model of centralized decision-making, decentralized decision-making and collaborative decision-making of supply chain members is constructed considering two cases of the investment of carbon emission reduction technology in the supply chain. Effects of Carbon Footprint Sensitivity Coefficient, Carbon Limit and Carbon Cost Reduction Coefficient on Optimal Decision-making and Emission Reduction of Supply Chain Members. The research shows that the linear relationship between carbon trading price and carbon quota, supply chain and manufacturer’s profit and carbon quotas are not increasing linearly, the government’s reasonable carbon quota can promote supply chain enterprises to effectively reduce carbon emissions; when consumers When the willingness to pay depends on the product’s carbon footprint, enterprises can make greater profits while reducing their carbon emissions by investing in carbon emission reduction technologies so as to achieve a coordinated development of environment and economy. When manufacturers and retailers work together to determine the level of carbon emission reduction through channel collaboration, the total carbon emissions in the supply chain is significantly reduced compared with the case of decentralized decision-making.
