Territorialized economic systems and productive purpose's informal communication practices : Study case of the French Arve valley and bar turning industry

What if the strength of a territorialized economic system did not depend only on his formal processes? This research paper attempts to investigate it, by unveiling a particular type of informal processes, that of the informal communication practices related to the of Marshallian externalities filiation corresponding to non-market interdependencies.Based on the conceptual framework of the neo-institutionalist economic theory, the author will characterize the existence of informal communication practices, responding to the characteristics of a tension between formal constraints and informal constraints. Secondly, based on the conceptual system of the non-standard economy, and in particular, that of the economy of proximities, the author will inventory and qualify the aforementioned practices, which belong to network communicationrelationships for productive purposes.This will enable us, within the framework of the study case focusing of a particular territorialized economic system, the French Arve valley and the bar turning industry activity, to empirically consider the existence of a system composed of three communication practices pattern and two communities, both informal, as well as the coexistence of two institutional systems.These informal mechanisms constitute a clear support in the economic field for the bar turning industry local's players. These same mechanisms correspond to practices and information related to economic and business intelligence. They can be of interest to the scientific community interested in territorialised economic mechanisms and clustering mechanisms, as well as practitioners wishing to access an in-depth understanding of a specific territorial reality other than through purely technical or business-oriented perspective.
