Entrepreneurship in a modern network economy, Reg. Studies 37, 395-405. In this survey paper the literature on entrepreneurship is summarized from the perspective of geographical seedbed conditions and network constellations. We argue that in many cases urban areas offer favourable incubator conditions for innovative entrepreneurship, as a result of economies of density and the opportunities created by the city as a nucleus of a broader network, both local and global. Clearly, network participation by creative entrepreneurs does not necessarily need an urban base, although informal spatial networks among specific business segments (e.g. ethnic niches) may be favourable for economic performance. We conclude that a modern entrepreneur tends to become increasingly a creative network operator and manager.
