摘要
为探究碳配额交易对碳减排效应的影响及对其协调机制,本文基于碳配额交易分别建立分散决策下零部件商与生产商单独减排投资、共同减排投资以及集中决策减排投资模型,对比不同减排投资模式下产品减排水平、产品定价效应及销量、供应链收益.研究发现:(1)碳配额交易下,集中决策较分散决策下产品减排水平更高,且分散决策下共同减排模式下产品减排水平最高.(2)供应链上下游企业进行减排将会提升产品销售量及供应链收益,集中决策下产品销量与供应链收益均高于分散决策.(3)碳配额交易下,供应链上下游共同减排投资并签订收益共享—成本分摊契约,能够实现集中决策模式下的最优协调机制.
Abstract
In the face of escalating global concerns about climate change,industries ubiquitously confront the daunting task of mitigating their carbon footprints.The manufacturing sector,a pivotal arena for the attainment of the"dual carbon"objectives,is experiencing an exigent demand for holistic emission curtailment throughout its supply chain.This investigation elucidates the ramifications of carbon quota trading in refining carbon mitiga-tion methodologies and their synergistic frameworks.Leveraging insights from carbon quota trading,models are formulated under a decentralized decision-making paradigm,wherein component vendors and manufacturers undertake emission reductions either in isolation or collaboratively.A centralized emission reduction decision-making model is also proposed.The carbon reduction magnitudes,product price structures,sales trajectories,and supply chain advantages are juxtaposed across these divergent emission curtailment models.Predicated on the intensity of emission abatement and value generation,the quintessential model for emission reduction within the ambit of carbon quota trading is indentified.Drawing on the example of a tire manufacturing supply chain,Company A(an upstream component purveyor)delivers essential rubber additives and adjuncts requisite for Company B's(a downstream tire producer)manufacturing processes.Collectively,this firm'strategic initia-tives within the supply chain facilitate pronounced carbon reduction in products.The findings underscore that galvanizing supply chain stakeholders to coalesce via profit-sharing and cost-allocation agreements not only averts losses stemming from game-theoretic dynamics but also accentuates the scale of emission abatement and amplifies supply chain yields.Such insights proffer invaluable strategic direction for government entities striving to expedite emission reduction trajectories in the manufacturing domain,concurrently furnishing a theoretical scaffold for supply chain businesses aspiring for win-win synergies.The primary findings of the research are as follows(1)Within the carbon quota trading framework,a centralized decision-making approach engenders a more pronounced product emission diminution than its decentralized counterpart.Notably,the concurrent emis-sion abatement strategy within the decentralized model manifests the most substantial product emission curtail-ment.(2)Emission abatement endeavors spearheaded by both upstream and downstream entities in the supply chain augment product turnover and enhance the cumulative supply chain yield.Products'turnover and supply chain yields under a centralized framework conspicuously eclipse those under decentralized decision-making.(3)Pertaining to carbon quota trading,supply chain entities can actualize an optimal coordination blueprint intrinsic to the centralized model by mutually committing to emission reductions and initiating profit-sharing and cost-allocation compacts.
