  This study measures the tendency to publish in international scientific
journals. For each of nearly 35 thousands Scopus-indexed journals, we derive
seven globalization indicators based on the composition of authors by country
of origin and other characteristics. These are subsequently scaled up to the
level of 174 countries and 27 disciplines between 2005 and 2017. The results
indicate that advanced countries maintain high globalization of scientific
communication that is not varying across disciplines. Social sciences and
health sciences are less globalized than physical and life sciences. Countries
of the former Soviet bloc score far lower on the globalization measures,
especially in social sciences or health sciences. Russia remains among the
least globalized during the whole period, with no upward trend. Contrary, China
has profoundly globalized its science system, gradually moving from the lowest
globalization figures to the world average. The paper concludes with
reflections on measurement issues and policy implications.
