信息共享对于闭环供应链协调有着非常重要的意义。通过对闭环供应链信息共享的内涵、载体和组织的分析，从信息共享的动力和供应链上、下游信息共享体系两个层次研究基于物联网技术上的闭环供应链信息共享体系构建的路径，并通过对闭环供应链信息共享体系的管理和技术前提进行的讨论。得出逐步推进、持续改善是其建设的最有效措施的结论。

英文摘要：

Information sharing has a very important significance for the closed-loop supply chain coordination. By analyzing the contents, carrier and organizations of information sharing path of closed-loop supply chain, this paper discusses the construction of closed-loop supply chain information sharing path based on Internet of Things technology from two levels： the dynamic of information sharing and the upstream and downstream information sharing system of the supply chain. Then the management and the technical prerequisites of information sharing system of the closed-loop supply are analysed. The paper concludes that a progressive and continuous improvement of the information sharing path is the most effective measure to the construction of the information sharing system of closed-loop supply chain.
