中文摘要：

信息共享是进行供应链管理的基础,也是影响供应链协调的关键决定因素。本文将技术能力用技术应用情况和技术联盟程度表示,将信息共享程度用信息共享质量和信息共享内容表示,通过问卷调查并运用结构方程模型进行实证研究。结果表明：技术联盟和技术应用对供应链信息共享质量和内容均有显著的正向影响;相较于技术应用,技术联盟对供应链信息共享质量和内容的影响更为显著。供应链企业应通过提高技术能力促进企业间信息共享,从而为实现供应链协调奠定基础。

英文摘要：

Information sharing is the basis for supply chain management, meanwhile, it is the key determinant of supply chain coordination. We use technical alliance and application to express the technology capacity, information sharing quality and content to show the information sharing degree. The empirical results indicate that technical alliance and application in technical capacity are positively relatively to information sharing quality and content, and by comparison to technical alliance, technical application＇s impact on information sharing quality and content is more pronotmced. Supply chain enterprise should promote information sharing by improving the technology ability, and it can lay the foundation for implementing the supply chain coordination.
