This book examines entrepreneurship from three interrelated perspectives. Firstly, it links entrepreneurship to innovation and to the generation, transformation and use of knowledge . Secondly, it inserts entrepreneurship in innovation systems of various types- national, sectoral and local. Thirdly, it views entrepreneurship not as a single event but as a process that evolves in time, from the pre-entry experience, to the entrepreneurial act, to the evolution of the entrepreneur and the new company. With chapters from a range of international contributors, the book answers questions such as; what are the main dimensions of knowledge intensive entrepreneurship? What are the factors affecting its emergence, evolution and performance? How important is knowledge intensive entrepreneurship for European growth and competitiveness? Is the situation of Central and Eastern Europe, engaged in a process of major economic and institutional transformation, similar or different from the one of Western Europe?
