During the last decade, we have witnessed a sustained growth of South Korea’s research output in terms of the world share
of publications in the Science Citation Index database. However, Korea’s citation performance is not yet as competitive as
publication performance. In this study, the authors examine the intellectual structure of Korean S&T field based on social
network analysis of journal-journal citation data using the ten Korean SCI journals as seed journals. The results reveal that
Korean SCI journals function more like publication places, neither research channels nor information sources among national
scientists. Thus, these journals may provide Korean scholars with access to international scientific communities by facilitating
the respective entry barriers. However, there are no citation relations based on their Korean background. Furthermore, we
intend to draw some policy implications which may be helpful to increase Korea’s research potential.
