GARCIA HERNANDEZ, Alejandra. A bibliometric analysis of scientific collaboration networks and their effect on productivity. Investig. bibl [online]. 2013, vol.27, n.59, pp.159-175. ISSN 2448-8321.

Bibliometric studies of scientific collaboration show a relationship between collaboration and scientists' productivity; however, little is known about how collaboration might inhibit or enhance scientific productivity. Social Network Analysis (SNA) provides tools and methods for analyzing the structure of collaboration networks. Some bibliometric studies of co-authorship networks are applying network techniques to study scientific networks within certain disciplines. This paper is focused on the relationship between co-authorship networks and productivity of research groups. The study samples 76 academic research groups of the Polytechnic University of Valencia. The principal results show that there is a relationship between network variables and a given group's productivity, demonstrating that network centralization and size are important variables explaining variations of a group's productivity. Moreover, network density and structural gaps in a network had no effect on a group's productivity.
