Abstract
In this paper we study networks of academic researchers on an aggregated laboratory scale. We propose a measurement of the intensity of cooperation between laboratories, and attempt to account for its intra- and inter-town variations in relation to a number of characteristics: geographic distance between laboratories, specialization of laboratories, size of their scientific community, productivity, quality of their publications and international openness. Cooperative relations are identified on the basis of data on co-publication. These data concern French physicists from the Centre National de la Recherche Scientifique (CNRS), between 1992 and 1997.
