Le centre d'affaire historique de Paris : quel pouvoir structurant sur l'espace économique en Ile-de-France ?

The aim of this paper is to analyze the influence of the CBD of Paris on the economic activity of Ile-de-France. First, we evaluate the employment density gradient and its significance using density functions estimated for total employment and six sectors. The results indicate that the CBD still globally influences employment in Ile-de-France but that its influence is different across sectors. Secondly, we perform local regressions and show that the employment density gradient depends on the distance from the CBD a commune is located and on the direction considered. In all cases, heteroskedasticity robust bayesian spatial econometric techniques are used.
