中文摘要

      针对中小型供应链成员是否建立基于区块链技术的信息共享平台以及建立后的价值问题, 考虑消费者的 质量和价格敏感, 分析了由零售商主导并包含两个地位不等的制造商的供应链中基于区块链技术的信息共享问题. 本文分别构建传统合作模型、基于区块链技术的信息共享短期模型和长期模型, 探讨不同模式下的供应链价值和 模式选择. 结果表明: 短期而言, 建立基于区块链技术的信息共享平台会扩大制造商之间的地位差距, 致使强者愈 强而弱者愈弱, 零售商的利润会受损. 长期而言, 信息共享带来的质量努力效应会缩小制造商之间的差距并增加利 润, 零售商和整个供应链在经历短期的阵痛之后利润会显著增加. 可知当消费者对价格和质量敏感性较高时, 建立 基于区块链技术的信息共享平台对实力较强的制造商是有利的, 对实力较弱的制造商是不利的, 对供应链是长期有 利的, 否则, 不建立基于区块链技术的信息共享平台对供应链和实力较弱的制造商是有利的

英文摘要

      To address the question of whether small and medium-sized supply chain members establish an information sharing platform based on blockchain technology and the value of the establishment, information sharing based on blockchain technology in a supply chain dominated by a retailer and containing two manufacturers with unequal status is analysed by considering the quality and price sensitivity of consumers. The article constructs a traditional cooperation model, a short-term model of information sharing based on blockchain technology, and a long-term model, respectively, to explore the value of the supply chain and model selection under different models. The results show that in the short term, the establishment of an information sharing platform based on blockchain technology will widen the status gap between manufacturers, resulting in the strong getting stronger and the weak getting weaker, and the profit of retailers will be damaged. In the long run, the quality endeavour effect of information sharing will narrow the gap between manufacturers and increase profits, and retailers and the entire supply chain will experience significant profit increases after short-term pain. It can be seen that when consumers are more sensitive to price and quality, the establishment of an information sharing platform based on blockchain technology is advantageous to stronger manufacturers, disadvantageous to weaker manufacturers, and beneficial to the supply chain in the long run; otherwise, the absence of an information sharing platform based on blockchain technology is advantageous to the supply chain and weaker manufacturers.
