The purpose of this paper is to analyse the evolutionary pattern of international research collaborations. Using publication data from 1997 to 2012, this study decomposes international collaborations into two complementary types, intra-collaboration (within the same geographical area) and inter-collaboration (across different geographical areas). Our results show that the geographical concentration of international research collaborations is reducing. The formation of new network structure of international research collaborations is driven by the increase of inter-research collaborations of countries across different geographical areas rather than intra-collaborations of countries within the same geographical area.
