摘要/Abstract

摘要： 信息不对称是阻碍供应链多主体协同减排的主要因素，针对消费者隐匿低碳偏好导致的供应链协同减排效率损失问题，通过与基于委托-代理理论的供应链减排信息甄别机制比较，设计了基于区块链驱动的供应链协同减排信息共享机制。研究表明，消费者获得额外的信息租金是导致供应链减排效率损失的主要因素，生产商和供应商通过分担一定比例的“区块链+协同减排”投资成本，可以获得额外的信息共享收益。“区块链+协同减排”信息共享机制在消除信息租金的同时，可以有效提高供应链收益，并且存在一最优收益分配比例使得生产商与供应商收益达到均衡以及供应链收益达到最优。“区块链+协同减排”信息共享机制可以有效提高供应链上下游企业协同减排效率，是推进我国“十四五”时期减排任务的重要路径之一。

Abstract: information asymmetry is the main factor that hinders the supply chain multi-agent collaborative emission reduction. Aiming at the efficiency loss of supply chain collaborative emission reduction caused by consumers' hidden low-carbon preference, by comparing with the supply chain emission reduction information screening mechanism based on principal-agent theory, a supply chain collaborative emission reduction information sharing mechanism based on blockchain drive is designed.The research shows that consumer’s extra information rent is the main factor leading to the loss of emission reduction efficiency in the supply chain. Manufacturer and supplier can obtain additional information sharing benefits by sharing a certain proportion of the cost of “blockchain+collaborative emission reduction” technology investment.The information sharing mechanism of “blockchain+collaborative emission reduction” can effectively improve the revenue of the supply chain while eliminating the information rent, and there is an optimal proportion to balance the revenue of manufacturer and supplier and optimize the revenue of the supply chain.The information sharing mechanism of “blockchain+collaborative emission reduction” can effectively improve the collaborative emission reduction efficiency of upstream and downstream enterprises in the supply chain, which is one of the important paths to promote the emission reduction task in the 14th Five Year Plan period.
