Size matters: the total of internationally co-authored scientific articles in 2015 corresponds to the global scientific production in 1993. The steady and systematic growth in international collaboration in science provides a strong basis for an emerging GIS. Therefore, it is important to map international flows that connect different national systems of innovation. This paper tracks knowledge flows through cross-border co-authorships in scientific publications, through a database with 10 million papers published in 2000, 2003, 2006 2009, 2012 and 2015. The data show an increase in international co-authorships from 10.7% in 2000 to 21.3% in 2015. However, this growth has network properties, since the number of international flows has grown from 545,372 in 2000 to 7,083,075 in 2015. Those international co-authorships signal networks of universities and research institutes, providing international connections to firms that eventually interact only locally with those universities and research institutes. The growth in the size, dimension and quality of those scientific flows strengthens a broad and variegated mosaic of interconnections can be grasped by the size of the network of cross-border co-authorships, a network that might be supporting an emerging and rudimentary global system of innovation.
