Still focus on the production side, we neglect consumption as an important redistribution mechanism in a world where consumers are relatively foot-free. The process of metropolisation changes the way territories deal with them and take part in the metropolitan economics. Recent papers which talk about "consumer city" and "consumption amenities" give a more important role to the metropolis as a consumption center to explain economic performance. Hinterland plays probably a great but yet neglected role in the success of the metropolitan economy. Conversely the metropolitan process certainly helps suburban economics. The economic reshaping of intra-metropolitan activities also concerns consumer services. That's why some peripheral communities are now in position to count on local consumption to grow. We try to understand how the metropolitan consumption can affect positively suburban economics by raising conso-oriented employment. Keeping a great attention on the economic base theory, we identify conso-oriented activities by assignment method. We also use cross-referencing data to estimate the amount of euros spent across the metropolitan area. Afterwards we can trace the evolution of the spatial distribution of conso-oriented employment and the performance of different spaces in the metropolitan area. That shows that urban sprawl raises employment not only for the outer-suburb by a 'catch-up' effect but also in the inner part where a huge supply of goods and services can meet unfulfilled needs of the outer one. It's finally a question of economic relationships between Paris and its inner-suburb, and the whole agglomeration and the low-density metropolitan spaces.
