Abstract: Considering the low carbon perception sensitive characteristics of consumers,the low carbon products and ordinary products were produced simultaneously by manufacturers to meet differentiated consumer demand.The manufacturer's supply chain decision-making model without blockchain and that with blockchain were constructed for comparative analysis.The results showed that under a certain blockchain cost threshold,the implementation of blockchain by manufacturers was not only conducive to the improvement of corporate profits,but also conducive to the improvement of retailers'profits and consumer surplus,comparing the two modes of implementing blockchain technology and the non-implementing blockchain technology,the higher the valuation impairment level of low-carbon products,the lower the discount level of ordinary products,and when the lower the blockchain cost threshold,the blockchain technology was prior adopted by manufacturers;the larger the percentage of carbon-sensitive consumers,the greater the profits for manufacturers and retailers,and the profit fluctuation of manufacturers was always higher than that of retailers,however,the proportion of carbon-sensitive consumers had no impact on the threshold of the cost of implementing blockchain for manufacturers;manufacturers used blockchain to increase consumers'demand for low-carbon products and reduce demand for ordinary products,while increasing the retail and wholesale prices of low-carbon products.

摘要： 鉴于消费者低碳感知敏感的特点,制造商同时生产低碳产品和普通产品来满足消费者差异化需求,构建并对比分析制造商未采用区块链和采用区块链的供应链决策模型。研究发现,在一定区块链成本阈值内,制造商实施区块链不仅有利于改善自身利润,还提高了零售商利润和消费者剩余,对比两种模式,低碳产品估值削弱因子越高,普通产品估值折扣因子越低,区块链成本阈值低时,制造商会优先采用区块链技术;碳感知敏感消费者占比越大,制造商和零售商的利润越大,而且制造商的利润变化程度始终高于零售商,但碳感知敏感消费者占比对区块链成本阈值无影响;制造商采用区块链增加消费者对低碳产品的需求,降低对普通产品的需求,同时提高低碳产品的零售价和批发价。
