[目的/意义]为了更深入地把握供应链信息生态链的发展规律和运行机制，同时为供应链信息管理提供更具实践意义的帮助。[方法/过程]在理论分析供应链信息生态链信息传递内涵的基础上，归纳了5项信息传递效率指标，并提出21项关于影响因素的研究假设，调查并整理了247份有效数据，利用结构方程模型进行实证检验。[结果/结论]研究表明信息化标准程度、信息发送能力和发送意愿、信息接收意愿和接收能力与供应链信息生态链的信息传递效率正相关；关系强度、信息势差、网络密度、网络中心度与信息发送意愿和信息接收意愿正相关；信息生态位重叠度与信息发送意愿和信息接收意愿负相关；关系强度、网络中心度、网络范围与信息发送能力和信息接收能力正相关。%Purpose/Significance] In order to grasp the law of supply chain information ecological chain development more deeply and provide more practical help to the information management of supply chain, [ Method/Process] this article summed up 5 index, put for-ward 21 hypotheses, sorted out 247 copies of the survey data, and used structural equation model to carry out an empirical test. [ Result/Conclusion] The results show that the degree of informatization standards, the ability and the willingness to send information, the ability and willingness to receive information are positively related to the information transmission efficiency; the relationship strength, informa-tion potential difference, network density and network centrality are positively related to the information transmitting and receiving inten-tion;information niche overlap is negatively related to willingness to send and receive information;relationship strength, network centrali-ty, network coverage are positively related to the information receiving and transmitting ability.
