摘　　要：为了解决传统供应链的上下游信息常常出现各时间节点信息不对称、信息供需方交流关系不平等情况导致抬高信用成本、影响整体沟通效率等问题,依托互联网平台,利用区块链技术,将供应方、运输方、需求方和监管者等供应链上的信息供需方依照时间轴的先后顺序依次串联起来,建立粮食供应链溯源信息多方共享机制。结果发现,在供应链的不同节点实时更新该批粮食的种植地环境状况、化肥施用情况、质量品质、物流储藏、销售方向和顾客特点等信息,解决了传统信息追溯手段追溯效率低下问题,降低了信用成本,为实现数字信息技术背景下粮食产业的升级转型提供了可能的发展路径。In the traditional supply chain,the upstream and downstream information suppliers are in a com‐plex game relationship,which often leads to information asymmetry at each time node and unequal commu‐nication relationship between all parties,which often raises the credit cost and affects the overall communi‐cation efficiency.In order to solve the above problems,we try to establish a multi-party information sharing mechanism.Relying on the Internet platform and using the blockchain technology,the suppliers,transport‐ers,demanders and regulators in the supply chain were connected in sequence according to the order of the time axis,and the multi-party sharing mechanism of traceability information in the food supply chain was established.In different nodes of the supply chain,the periodic information of the planting site environment,fertilizer application,quality,logistics storage,sales direction and customer characteristics of the batch of grain were updated in real time.It solves the problem of low efficiency of traditional information traceability methods and reduces the credit cost,and provides a possible development path for the upgrading and trans‐formation of grain industry under the background of digital information technology.
