| Research Abstract |
Under internationalization of research activities,two major themes have still not been investigated: factors related to international co-authorship and the reasons behind the higher citation rates of internationally-collaborated articles. Therefore, this study examines those two themes by empirical analysis using meta-information of academic papers. One of the results gained from analysis on papers published in the past 20 years in Nature and Science using a count data regression model indicated several factors that have a positive relationship with the production of academic papers: investment on R&D and the number of researchers, the number of international students, and European Union membership. Analysis using a database of papers in the field of chemistry showed positive correlations between research performance (number of papers and their times cited) and the degree of international collaboration.
