Abstract
Electronic commerce poses economic and management problems that are well known in some aspects (integration dynamics, branding) and new aspects by others (dynamics of building business models in a context of strong growth, links between production and knowledge economy, hybridisation of distribution channels). In addition, there are more specific questions raised by the strength and nature of the growth of electronic transactions: managerial (development of strategies, learning skills of firms, mastery of new commercial and logistical skills, etc.) as well as regulations (consistency of taxes, protection of intellectual property, security of sites, guarantee of personal data). The following issue is intended to shed light on these questions and is the direct counterpart of a previous delivery of Networks devoted to internal developments in firms. In particular, it is based on the same concern: support case studies and presentation of empirical material.
