Définition
Economic spheres are defined according to the logic inducing the location of activity. The notion of sphere is used in the "Clap" information system (Connaissance locale de l'appareil productif, local knowledge of the production system) to jointly analyse localised data relating to the positions held and the wages paid.
- The productive sphere: employment follows companies for the sectors oriented towards foreign markets. The main sectors concerned are industry, energy, services to enterprises, transport of goods, wholesale, and part of real-estate activity.
- The residential economy sphere: employment follows the population for market services to people; like services to individuals, construction, education (excluding the civil service), health, social action, retail, financial activities and transport of passengers.
- The public sphere: includes all jobs in the civil service (State civil service, territorial and hospital civil service).
Remarque
This breakdown remains schematic because all sectors are productive in that they create added value, and services to people and tourism are not immune to economic ups and downs. The content of activities in the civil service is itself highly diverse and the location of public jobs may obey variable rationales depending on whether the imperatives of proximity or centrality prevail.
