The lack of previous literature reviews on the subject, which would reveal the key questions to be studied, has, however, led us to analyse the contents of academic texts published between 1997 and 2006 in major international scientific journals. Accordingly, selected works were studied from three angles: the evolution of their scientific quality, the lines of research to which they are linked, and the methodology employed. This enabled us to determine the present level of development and to propose lines for future research. Keywords: Industrial district, cluster, territory, inter-organisational networks, content analysis.
