Abstract
The recent growth of new ethnic populations in Western societies raised lots of issues. In fact, the ethnic activity is not any more a question of historic interest; nor is it the concern of the company. Because new ethnic populations grew at the same time as Western economies, they are in a phase of slow growth and are facing the massive technological challenge; the ethnic adaptation and the mobility are central questions(Waldinger 1990). In Europe, the activities managed by persons of minority ethnic groups were always present, but changeable historic circumstances increased jutting out to them and visibility during the last decades.
First of all, the important immigration of former colonies of Southern Europe and North Africa led to a considerable migration. Secondly, thirty years of economic change caused a fundamental transformation of the labor market and a general change of the employment in big companies to the independent work in young companies. This tendency struck certain groups of immigrant much harder than the other native populations, which is reflected by the higher unemployment rate among the immigrants (Barret and all. 1996). Thirdly, the second-hand structure for ethnic activities became more favorable as the change of Europe the industrial structure led to a reappearance of small and medium-sized enterprises (Blaschke 1990).
