ABSTRACT
The previous chapters have shown how digital technologies enable complex multiscalar, global business practices by placing at the disposal of organizations pools of human resources unequally distributed over space. To analyze the effects of IT on places and regions requires that we confront directly the clash between two complementary tendencies: agglomeration and dispersion. After presenting the simple dynamics that govern the processes of productive poles dedicated to the digital economy, we will see that the standard model of agglomeration-that of Silicon Valley-tends towards geographical diffusion, undergoing a process of deterioration and increasing complexity as a result of the dispersion of economic activity seen in Chapters 6 and 7.
