在碳减排约束下,通过对低碳供应链进行建模,借助数值实验,运用博弈论的方法研究产品碳系数和制造商公平关切行为对低碳供应链定价策略、碳减排水平、供应链各方利润以及供应链整体利润的影响.研究结果表明:1)集中式决策模式下,产品碳减排水平和供应链整体利润要高于分散式决策.制造商客观存在的公平关切属性会进一步降低产品碳减排水平和供应链整体利润,且随着制造商公平关切程度的增大,供应链各方成员以及供应链整体利润均会减小,但制造商利润所占供应链总利润的份额却在不断增大;2)三种不同供应链决策模式下,低碳产品零售价格、碳减排水平和供应链利润均会随着碳系数的增大而增大;3)碳减排投资成本分担契约的实施能够促进低碳产品零售价格降低,销量增加,从而能够有效地提高低碳供应链的整体效率.
Under the constraint of carbon emission reduction, through the modeling of low-carbon supply chain, using numerical experiments, using game theory to study the product carbon coefficient and fair-cut behavior of manufacturers, the pricing strategy of low-carbon supply chain, carbon emission reduction, supply The profit of each chain and the profit of the whole supply chain.The results show that: 1) Under the centralized decision-making mode, the level of carbon emission reduction and the overall profit of the supply chain are higher than the decentralized decision-making.The objective existence fairness of the manufacturers Further reduce the level of product carbon emissions and the overall profit of the supply chain, and as manufacturers become more concerned about the degree of fairness, supply chain members and the overall supply chain will be reduced profits, but the manufacturer’s profit share of total supply chain profits The share of the carbon market is increasing; 2) Under the three different supply chain decision modes, the retail price of carbon products, the level of carbon emission reduction and the profit of the supply chain all increase with the increase of carbon coefficient; 3) The implementation of the investment cost sharing contract can promote the reduction of the retail price of low-carbon products and the increase of sales volume, so as to effectively improve the overall efficiency of the low-carbon supply chain.
