Stratégies de localisation des firmes du secteur TIC : du cyber district au district lisière

This paper proposes an explanation for the emergence of internet activities cluster: the cyber-district. This cluster is characterized with a very fast evolution cycle whereas spatial dynamics are more often longer. We define the principle of cascade location as the product of individual decision making based on the information externalities and mimetic behaviours and as supporting the cluster temporality. We compare the cluster to a good experience where value is revealed ex-post. However, as the cyber-district is more instable than a district, based on productive complementarities and network externalities we could produce some regional policy recommendations associated with the replication and stability conditions of the cluster. Finally, we illustrate the evolution of a cyber-district with the Silicon Sentier located in Paris.
