Networks and geography in the economics of knowledge flows

This paper reviews the literature dealing with the economic geography of knowledge flows by summarising the most relevant problems and open questions that, according to the authors’ view, have been dealt in the past and should be dealt in the future by network analysis in order to model, understand and measure the structure and dynamics of knowledge flows. The interaction between “networks” and “geography” elements within a theoretical, methodological and empirical perspective is discussed throughout the paper by making reference to previous works by the authors and to the established literature. Thus, these references, far from being complete and exhaustive, are instrumental to the achievement of the paper’s goal: to demonstrate that “networks” and “geography” are the necessary ingredients for every study of the innovative process at any level of analysis, from individual agent to institution/organization, from the regional to the national and international level.
