Les productivités des régions françaises sur moyenne période

The aim of this article is to scan, in an accurate way, the French regional labor productivities on sectoral and aggregate levels during the 80?s. Taking from Baumol or Barro & Sala-i-Martin works, this paper enhances them by pointing out the sources of growth analyzed by the new growth theories (research effort, size effects), and by underlying the impact of labor cross-sectoral reallocations. It leads to moderate the regional convergence observed globally, which results mainly from cross-sectoral composition effects. Classification JEL : L00, O41, R1
