Integration et inegalite regionales : une relation en U inverse ?


  • Carl Gaigne


Les theories de la localisation et du commerce international mettent en evidence que l'integration regionale se manifeste tout d'abord par une phase de divergence et ensuite par une phase de convergence des economies. On montre que si l'on tient compte d'une baisse differenciee des couts de transport entre les secteurs industriels, alors la relation entre couts de transport et inegalites spatiales peut se modifier. En effet, si la baisse des couts de transport des biens intermediaires est plus rapide que celle des biens finals, alors la dispersion de la production industrielle peut etre favorisee. A l'inverse, si la baisse des couts de transport des biens finals est plus rapide, alors l'activite industrielle tend a se concentrer geographiquement.
