The Effect of Co-authorship Network on Research Performance of Scholars: A Correlation Analysis

Collaborative research has been increasingly celebrated by the science community, and there are many researches proving that the co-authorship system has positive effect on research performance. In this paper, the correlation between collaborations and research performance was explored in the field of graduate education in China. Results from the analysis of SPSS suggest that the research collaboration system has significant influence on the quantity and quality of research, but not on the h-index. Additionally, it is found that the collaboration papers are conductive to improve the h-index of the author. Consequently, it can be stated that the co-authorship of researchers can be used to assess the performance of researchers in the field of graduate education in China and the scholars in the field should collaborate more and endeavor to be the leader during collaboration process.
