碳交易下考虑产品替代性的供应链减排决策研究

在碳交易背景下,针对企业单一的减排方式,提出了能源费用托管型合作模式的外包减排,并对两种减排方式 进行对比分析。 构建自主减排与外包减排 Stackelberg 博弈模型,比较分析交叉价格弹性、碳交易价格及减排投资系数 对两种减排方式下企业利润和碳减排量的影响,进一步细化影响选择减排方式的因素,采用算例仿真验证模型的有效 性。 研究结果表明:无论哪种减排方式,企业碳减排量和利润与交叉价格弹性系数成正向变动关系;碳交易价格增长, 会调动制造商减排积极性,产品的碳减排量增加,而对利润产生负效应;减排投资系数的增大,对企业减排起到负向阻 碍作用;节能服务公司与制造商自主减排投资系数比影响供应链选择减排方式,当减排投资系数比小于阈值时,企业 应选择能源费用托管型合作模式的外包减排,同时决策因素的变动会影响其选择减排方式的时机。

Influence of Supply Chain Emission Reduction Strategy Considering Product Substitution under Carbon Cap-andTrade

In the context of carbon cap-and-trade the outsourced emission reduction with energy cost trusteeship cooperation model was proposed for the single emission reduction mode of enterprises and the two emission reduction modes were compared and analyzed. The Stackelberg game model of autonomous emission reduction and outsourced emission reduction was constructed to compare and analyze the effects of cross-price elasticity carbon trading price and emission reduction investment coefficient on corporate profits and carbon emission reduction under the two emission reduction methods. The factors affecting the choice of emission reduction methods were further elaborated. The effectiveness of the model was verified by simulation. The results show that no matter what kind of emission reduction method the carbon emission reduction and profit of enterprises have a positive relationship with the cross-price elasticity coefficient. The increase of carbon trading price will mobilize the enthusiasm of manufacturers to reduce emissions and the carbon emission reduction of products will increase which will have a negative effect on profits. The increase in emission reduction investment coefficient has a negative hindering effect on the emission reduction of enterprises. The independent emission reduction investment coefficient ratio between the energy-saving service company and the manufacturer affects the choice of emission reduction mode of the supply chain. When the emission reduction investment coefficient ratio is less than the threshold the enterprise should choose the outsourcing emission reduction mode of energy cost custody cooperation and the change of decision-making factors will affect the timing of its choice of emission reduction mode.
