RT journal article T1 An empirical analysis of individual and collective determinants of international research collaboration A1 Frutos Belizón, Jesús de A1 García Carbonell, Natalia A1 Guerrero Alba, Félix A1 Sánchez Gardey, Gonzalo A2 Organización de Empresas K1 Scientific productivity K1 Localists K1 Internationalits K1 Researchers AB International research collaboration is a crucial determinant of scientific productivity, but it remains an underdeveloped task for governments, universities and research systems. Despite important economic and institutional efforts to promote collaborations, not all researchers establish successful international connections during their academic careers. This lack of international contacts hinders knowledge transfer from a broader perspective, limiting, in a way, the advancement of science. This paper analyses these factors—individ- ual and collective—affecting research collaboration in the international context through a hierarchical multiple regression analysis of a sample of 954 Spanish academic researchers. We found that collective factors such as research team social capital—including structural and cognitive dimensions—and team orientation toward research and team productivity clearly affect international collaboration levels. Furthermore, contrary to our expectations, researchers’ human capital and motivation, and the principal investigator’s knowledge-ori- ented leadership, exerted only a very weak effect, which also is discussed in the paper’s final section.
