Cahier 2015-10| Title: | Network proximity in the geography of research collaboration | | Abstract: | This paper deals with the questions of how network proximity influences the structure of inter-regional collaborations and how it interacts with geography. I first introduce a new, theoretically grounded measure of inter-regional network proximity. Then, I use data on European scientific co-publications in the field of chemistry between 2001 and 2005 to assess those questions. The main findings reveal that inter-regional network proximity is important in determining future collaborations but its effect is mediated by geography. Most importantly, a clear substitution pattern is revealed showing that network proximity benefits mostly international collaborations. | | Keyword(s): | network proximity; gravity model; research collaboration; network formation; co-publication | | Auteur(s) : | BERGE Laurent | | JEL Class.: | D85, O31, R12 | Télécharger le cahier Retour à la liste des Cahier du GRETHA (2015) |
