Based on the research projects submitted to the 6th Framework Program of the European Union, this paper studies cooperative networks in micro and nanotechnologies. Our objective is twofold. First, using the statistical tools of the social network analysis, we characterise the structure of the R&D collaborations established between firms. Second, we investigate the determinants of this structure, by analysing the individual choices of cooperation. A binary choice model is used to put forward the existence of network effects alongside other microeconomic determinants of cooperation. Our findings suggest that network effects are present, so that probability of collaboration is influenced by each individual's position within the network. It seems that social distance matters more than geographical distance. We also provide some evidence that similar firms (in terms of research potential) are more likely to collaborate together
