Abstract
For most of their history, retail units have operated within a well-defined market structure and in accordance with a clear regulatory policy. However, in recent years traditional retail shops have been replaced firstly by supermarkets, and then by hypermarkets, which has dramatically changed the market structure and the regulatory policy (Barros, 2006). This coupled with radical improvements in the consumer living standards, has made it possible to revolutionize the food distribution system. Other factors which have most strongly influenced this change are related to: household bdisposable income, urban population, active population, changes in expenditure and consumer mobility and households’ appliances.
