An empirical study on the collaboration of scholars in graduate education: based on the social network analysis

This study applies social network analysis to study the collaboration of scholars in the field of graduate education. The result shows that from 1980 to 2015, the percentage of co-authored papers remarkably increases and a growing number of core scholars appears in the the field of graduate education. The density of co-authorship network is low but is increasing. According to analysis on the patterns of subnets in the whole co-authorship network, the collaboration of scholars develop from single authorship pattern to complete and potential co-authorship pattern. Some core research groups have already formed in graduate education, their academic contributions greatly promote the development of graduate education.
