TIC et réorganisation spatiale des activités économiques : introduction

Abstract

This introduction focuses on the relation between economics of information and communication technologies (TIC) economics and spatial re-organization of economic activities. In the first time, we show the necessity of decomposition of the ICT sector and the weight of interactions and externalities in a network based economy. In the second time, we show that three questions have to be studied: the role of telecommunication networks and their diffusion in local development, ICT diffusion and re-organization of economic activities, and the peculiar case of the location of ICT firms. This introduction ends up by a short presentation of the contributions of this volume.
