The purpose of this is to map the intellectual structure of supply chain management(SCM) studies in this century, this study proposes a generic model of invisible network of knowledge through which the most important publications and the most influential scholars as well as the correlations among these publications can be identified. In this study, bibliometric and social network analysis techniques are used to investigate the intellectual pillars of the diversification literature. By analyzing 152,181 citations of 3,463 articles published in SSCI and SCI journals in diversification area between 2001and 2012, this study maps an invisible network of knowledge of diversification studies. The study found that the results of the mapping present a solid foundation for a knowledge network in diversification area ,and help identify the invisible network of knowledge that traces the evolution of SCM research, and provide a valuable tool for researchers toaccess the literature in this area.
