Abstract A rise in second-generation migrant entrepreneurs and an increasing focus on modern economic sectors have become new trends in migrant entrepreneurship in recent years. Although traditional sectors are still the most popular among the first-generation migrant entrepreneurs, because of the increasing pressure and their high competitiveness in traditional areas, nowadays new market niches are rapidly developing. While the first generation has more often become active in new areas such as the producer services sector which includes finance, insurance, real estate and business-related professional services, the second generation has contributed to the emergence of new areas of immigrant business activity such as the ICT sector and the creative industries. Against this background, this study focuses on the external orientations of the second-generation migrant entrepreneurs by addressing in particular the way – and the extent to which – the choice for entrepreneurship is made by higher-educated young ethnic generations. This is a new field of entrepreneurship research in many European countries. The empirical data of our study is based on in-depth personal interviews held in the first half of 2007. We employed a recently developed multivariate qualitative classification method, coined rough set analysis, in order to investigate the motivation, goals and strategies of second generation Turkish entrepreneurs in the ICT and the financial services sector in the Netherlands. The results of our study show that the second generation Turkish entrepreneurs in the Netherlands have started to be involved in new and non-traditional sectors like ICT and financial services sectors. The motivation and driving forces of the second-generation Turkish entrepreneurs are stemming from both their personal characteristics shaped by their higher educational level and their previous working experience as an employee or entrepreneur in the same sector. The demand for and a gap in the sector as well as the growing and promising structure of the sector play also an important role in pulling the second generation Turkish immigrants to become entrepreneur in these new sectors.
