Les systèmes productifs urbains : des clusters aux « clusties »

In this paper, we propose the keyword of « clusty » in order to go over two main paradigms in Regional Science. The first one is driven by Urban Economics and particularly the economics of large metropolises, and the second by the geography of innovation and industrial economics. Both are useful but they have to be more connected to be able to explain why large cities are often the locus where urban growth, innovation and power networks reinforce each other through time.
