Аннотация:The paper focuses on the patterns of evolution of the structure of global scientific
collaboration over the most recent historical period. Among the multiple
approaches to measuring such collaboration we choose to investigate the
evolution of the international co-authorship network over a 25-year-long
period (from 1991 to 2016). We build a series of networks of main international
co-authorship partners using the data obtained from Scopus
Elsevier database. Our analysis reveals two markedly different patterns
of the network evolution. At the general level, it has been increasingly
turning into a ‘hub-and-spoke’ network where one central hub, the USA,
clearly dominates nearly the whole of the network. However, if the impact
of the USA is not taken into account, we discover a second level of the
network structure with remarkably different patterns – instead of one single
hub, there exist a number of centers with their respective clusters, and
this structure has not been gravitating towards becoming more concentrated.
If anything, its evolution has taken quite the opposite path, with
a number of new centers emerging recently with their respective clusters
of countries.
