This study examines the research productivity of Hong Kong academics. Specifically, it explores the individual and institutional factors that contribute to their productivity while also comparing determinants across academic disciplines. We have conducted OLS regression analysis using the international survey data from "The Changing Academics Profession." We found that Hong Kong academics are highly internationalized in terms of research activities. Moreover, research productivity is influenced by a number of factors, including personal characteristics, workload, differences in research styles, and institutional characteristics. In addition, considerable variation exists regarding the determinants of research productivity across disciplinary categories.
