摘要
本文考虑由供应商、生产商和消费者组成的供应链,供应商和生产商根据市场情况决策碳信息披露度及产品溢价.引入消费者信息信任度、消费者信息敏感度和信息共享收益系数等参数,分别构建了信息不对称下的供应链碳信息披露模型以及基于区块链技术的供应链碳信息共享模型,比较分析了不同决策模型中的最优决策.研究表明:1)随碳信息披露成本系数的增大,供应链决策分为供应商和生产商碳信息全披露,仅生产商碳信息全披露以及供应商和生产商碳信息部分披露三个阶段,决策主体的最优决策整体呈下降趋势. 2)存在某一碳信息上链成本系数临界阈值,使得供应商的碳信息披露度更高,除此之外,生产商的最优碳信息披露度始终不低于供应商;当产品初始价格小于某阈值时,生产商的最优产品溢价更高;且生产商的最优决策对相关参数的变化更敏感. 3)当碳信息上链成本系数小于一定比例的传统碳信息披露成本系数时,“区块链+碳信息”共享机制下决策主体的利润远高于信息不对称下的利润.
A supply chain consisting of suppliers,producers and consumers,and the suppliers and producers decide the carbon information disclosure degree and product premium according to the market situation.Parameters such as consumer information trust,consumer information sensitivity and information sharing benefit coefficient were introduced to construct a supply chain carbon information disclosure model under information asymmetry and a supply chain carbon information sharing model based on blockchain technology,and the optimal decision of different decision models was compared and analyzed.The results show that:1)With the increase of the cost coefficient of carbon information disclosure,the decision-making of the supply chain is divided into three stages:Full disclosure of carbon information of suppliers and producers,full disclosure of carbon information of producers and partial disclosure of carbon information of suppliers and producers,and the optimal decision-making of the decision-making body shows a downward trend.2)Except for the interval of the cost coefficient of a certain carbon information chain,the optimal carbon information disclosure degree of the manufacturer is always no lower than that of the supplier;when the initial price of the product is less than a certain threshold,the premium of the manufacturer’s optimal product is higher.And the manufacturer’s optimal decision is more sensitive to the change of related parameters.3)When the cost coefficient of carbon information on-chain is less than the cost coefficient of traditional carbon information disclosure,the profit of the decision-making subject under the“blockchain+carbon information”sharing mechanism is much higher than the profit under information asymmetry.
