笔者以由一个供应商和一个制造商组成的两级供应链为对象,研究在政府征收碳税和产品碳足迹影响市场需求的情况下的企业减排决策,分析供应商和制造商基于转移支付契约的联合减排问题,探索不同参数对供应商和制造商减排量和利润的影响。研究显示:制造商可以通过提高自身减排量和为供应商减排提供转移支付激励其提高减排量;联合减排能够实现供应链产品碳足迹的优化和利润的帕累托改进;联合减排时的最优转移支付系数与企业的减排成本系数无关;政府提高碳税能促使企业提高减排量,但联合减排前后的减排量增量会降低。
Based on a two-level supply chain composed of one supplier and one manufacturer, the author studies the corporate emission reduction decision-making under the condition that the government imposes the carbon tax and the product carbon footprint affect the market demand, and analyzes the suppliers ’and manufacturers’ The issue of joint emission reductions from contracts explores the impact of different parameters on emission reductions and profits of suppliers and manufacturers. The research shows that manufacturers can stimulate their emission reductions by raising their own emission reductions and providing transfer payments for the suppliers to reduce emissions. Combined emission reduction can improve the Pareto improvement of the carbon footprint of the supply chain products and profits The optimal transfer payment coefficient is not related to the emission reduction cost of the enterprise; the government raising the carbon tax can promote the enterprises to increase the emission reduction, but the incremental emission before and after the joint emission reduction will decrease.
