Suburbs, boomburbs and exurbs : a multilevel approach of contextual effects and the production of suburban morphologies. : Methodological framework and exploratory results in Paris metropolitan region

摘要

This paper aims at providing a methodological framework that comprehends the different levels of intricate interactions in the prodution of suburban residential patterns. By doing so, I wish to introduce an analysis of the local contexts of production of suburban PUG. This will be eventually achieved by the means of quantitative analysis (multilevel spatial analysis of income patterns and morphological typologies of subdivisions) and qualitative data. In this aim, identifying recent enclaved subdivisions will be used as a proxy to study a representative sample of subdivisions in the suburban areas of Paris metropolitan region. A database of 909 enclaved subdivision provided by the Greater Paris Region Planning Agency (from now on IAU-IdF1) will be used to identify street patterns, local morphologies, nearby land uses. This requires focusing on three main issues that underlies the theoretical and methodological choices the paper will discuss and justify : first, an analysis of PUD morphological fragmentation ; second, a comparative study of socio-spatial fragmentation (based upon income data) and regulation practices, interactions between actors and suburban sprawl ; and at last, an effort towards a better understanding of the retraction of public space, resulting from planning and development choices. Indeed, we push the argument that analyzing public and private partnerships in the production of suburban residential spaces, requires to investigate several dimensions : theoretical issues of institutional regulations, interactions between individual strategies at a local scale, these of private operators and developers as well as these of the residents. At last, the paper aims at demonstrating how these numerous and divergent dimensions may be jointly analyzed by the means of quantitative and qualitative multi-level analysis that indetifiy production contexts and territorial outcomes.
