Based on the concept and calculation method of extensity centrality, which are newly proposed in 2009, the paper builds co-authorship networks by the data of the world’s top three journals in Management Information Systems(MIS)field, analyzes the components of networks and calculates the extensity centrality of authors in five components. Then, it surveys and analyzes the backgrounds and cooperators’ research fields of those authors whose extensity centrality scores are high. The results indicate that the whole cooperative behavior of researchers in MIS is more active.Many of the authors with high extensity centrality scores are well-known experts or scholars in MIS, and they cooperate with scholars coming from various fields. Therefore,extensity centrality can indeed be used to evaluate the importance of experts and scholars.
