摘　　要：制造商利用区块链技术记录和传递产品碳减排信息将提升消费者对低碳产品的信任和消费偏好。因此,将区块链的技术效应特征嵌入低碳供应链决策模型,研究零售商提供的不同激励契约下制造商实施区块链对碳减排、定价策略及企业利润的影响。研究表明:制造商实施区块链后的产品批发价格在无激励契约和成本分担契约下大于未实施区块链情形,但在收益共享契约下小于未实施区块链情形。制造商实施区块链后的产品零售价格在不同激励契约下均大于未实施区块链情形。无论制造商是否实施区块链,单位产品碳减排量在收益共享契约下最大,而产品批发价格和零售价格在收益共享契约下最小。仅当区块链应用成本小于一定阈值时,制造商实施区块链才能够提升单位产品碳减排量和自身利润。制造商实施区块链的成本条件阈值在收益共享契约下最大,在无激励契约下最小。制造商实施区块链若能改善自身利润,则一定能够改善零售商利润。消费者低碳偏好与价格敏感程度之间的关系影响供应链碳减排、定价策略以及制造商实施区块链的成本条件。Blockchain adoption by manufacturers to record and transmit carbon emission reduction information will increase consumers’trust and consumption preference for low-carbon products.In this paper,the technical effect characteristics of blockchain were embedded in the decision-making model of low-carbon supply chain,and the impact of manufacturers’implementation of blockchain on carbon emission reduction,pricing strategy and corporate profits under different incentive contracts provided by retailers was studied.The results showed that the wholesale price in blockchain adoption scenarios was higher than that without blockchain under no incentive contract and cost-sharing contract,but smaller than that without blockchain under the revenue-sharing contract.However,the retail price with the adoption of blockchain was higher than that without blockchain in all cases.Regardless of whether the manufacturer implements blockchain or not,the carbon emission reduction level was the largest,while the wholesale and retail prices were the smallest under the revenue-sharing contract.Only when the cost of blockchain application was less than a certain threshold,the adoption of blockchain could improve the carbon emission reduction level and manufacturers’profit.The cost threshold for manufacturers to implement blockchain was maximum under the revenue-sharing contract and minimum in the absence of incentive contract.If blockchain adoption by manufacturers improved their own profits,it would certainly improve retailers’profits.The relationship between low-carbon preference and price sensitivity of consumers affected carbon emission reduction level,pricing strategies and the cost conditions for manufacturers to implement blockchain.
