中文摘要：

为了探讨供应商合作与竞争优势之间的关系,并检验IT能力对二者关系的调节效应,以揭示制造商通过与供应商合作来提升竞争优势的作用机制.从战略采购、信息共享及供应商参与3个维度对供应商合作进行刻画,并运用176家制造企业的调研数据,采用多元线性回归及调节效应检验方法对假设进行实证验证.研究结果表明,战略采购与信息共享均对竞争优势有显著的正向影响,且IT能力对战略采购、信息共享与竞争优势之间的关系均有正向调节效应.供应商参与对竞争优势无显著影响,且IT能力对供应商参与和竞争优势之间的关系没有显著的调节效应.

英文摘要：

This study aims to investigate the relationship between supplier collaboration and com- petitive advantage as well as the moderating effect of IT implementation for Chinese manufacturers. This paper reviews literature on supplier collaboration and propose a conceptual model of supplier col- laboration in terms of three dimensions： strategic purchasing, information sharing and supplier in- volvement. Survey method is adopted in this study. Empirical analysis based on data from 176 manu- facturing enterprises indicates that both strategic purchasing and information sharing have significant positive effect on competitive advantage, and IT implementation moderates the relationship between the two dimensions of supplier collaboration, strategic purchasing and information sharing, and com- petitive advantage positively. However, supplier involvement has no significant impact on competitive advantage. Neither does IT implementation have significant moderating effect on relationship between supplier involvement and competitive advantage.
