  Knowledge production increasingly relies on mobility. However, its role as a
mechanism for knowledge recombination and dissemination remains largely
unknown. Based on 1,244,080 Web of Science publications from 1,435,729 authors
that we used to construct a panel dataset, we study the impact of
inter-regional publishing and scientists' mobility in fostering the workforce
composition of European countries during 2008-2017. Specifically, we collect
information on scientists who have published in one region and then published
elsewhere, and explore some determinants of regional and international
mobility. Preliminary findings suggest that while talent pools of researchers
are increasingly international, their movements seem to be steered by
geographical structures. Future research will investigate the impact of
mobility on the regional structure of scientific fields by accounting for the
appearance and disappearance of research topics over time.
