摘　　要：文章以一个绿色制造商和一个电子商务平台组成的二级电子商务供应链为研究对象,考虑消费者的绿色偏好和信任以及制造商的公平偏好特性,建立了引入区块链前后制造商公平中性和公平偏好四种情形下的博弈模型。通过比较四种情形下的最优决策和最优利润,探讨制造商的公平偏好和区块链对供应链的影响。研究发现,制造商的公平偏好能使自身的利润增加,但对电子平台和整个供应链系统是不利的,且偏好程度越大,影响越大。引入区块链后,当区块链的应用成本很低时,产品的绿色度、电子平台的利润、制造商的利润以及供应链的总利润都比引入之前高,但他们都会随着成本的增加而降低。成本超过某一阈值后,绿色度和利润都比引入区块链前更小。A game model under four cases including manufacturers'fairness neutrality and preference before and after the introduction of blockchain technology was built,with a secondary e⁃commerce supply chain composed of a green manufacturer and an e⁃commerce platform as the research object,considering consumers'green preferences,green trust,and manufacturers'fairness preference characteristics.The fairness preferences of manufacturers and the impact of blockchain on the supply chain were studied by means of comparing the optimal decisions and profits under four cases.The results show that the manufacturers'profits will increase when the fairness concerns are considered.However,these will be detrimental to electronic platforms and the entire sup⁃ply chain system,and the larger the degree of preference is,the more detrimental its impact is.After the introduction of block⁃chain,when the cost of blockchain is relatively low,the greenness of the product,the profits of electronic platforms,manu⁃facturers and the supply chain are all higher than before.Nevertheless,as the cost increases,they will decrease.The greenness and profits will be smaller than before the introduction of blockchain when the cost exceeds a certain threshold.
