During past decades, the economic reshaping of major French cities has raised the issue of the attractiveness and power of central business districts (CBD). In Paris, recent work suggest that the decline in employment in the city center is leading to a slackening in the attributes of Parisian centrality, causing relatively widespread urban sprawl. This paper is a contribution to the current debate. Based on an original spatial slicing of Île-de-France municipalities, the definition of key economic sectors, and growth, weight, and specialization as differentiation indicators, several hypotheses are tested. First, is the economic centrality of the Paris CBD really declining? Second, is it in fact growing thanks to the dissemination of control activities within nearby municipalities? Finally, are the economic profiles of peri-central municipalities and central neighborhoods growing increasingly similar? Our results moderate the generally pessimistic reading of the evolution of CBDs and emphasize the current persistence of centripetal forces in the economic geography of the Paris region.
