This rapid growth was not driven by a few specific institutions. Rather, it was possible because virtually all universities with STEM programs, regardless of their institutional mission, participated in scholarly publishing. Meanwhile, the Korean government implemented a special research funding initiative, Brain Korea 21, in 1999 to stimulate science production among universities. Using multilevel linear regression models, this dissertation examines the effect of the BK 21 program; it finds that BK 21 had a positive effect on publications, but that its effect turned insignificant when more comparable groups of universities were examined. This research also demonstrates that the scientific collaboration network in Korea has moved from one strongly dominated by a few specific actors to one with more actors participating more equally and significantly. By using an exclusive longitudinal data set of publications—a data set that had not previously been examined—the research reflected in this dissertation contributes to an understanding of the expansion of science production in Korea, changes in publication characteristics, the role of a government-funded project in enhancing science productivity, and the formation of a scientific collaboration network among Korean universities and other countries. Given the relatively short history of the Korean higher education system, this study provides a landscape of how science production has been developed in Korea since its beginning.
