The concept of 'entrepreneurial ecosystems' has emerged as a means for theorizing and making policy-decisions concerning entrepreneurship and economic development within and across cities and regions. Entrepreneurial Ecosystems in Cities and Regions assembles original contributions from scholars across the world to provide an in-depth analysis of a concept that has the capability to capture a dynamic global economy with entrepreneurial innovation at the crux of its future development. It addresses wider issues concerning the evolution of new forms of industrial organisation. The book develops an agenda and understanding that aims to build upon the early explosion of interest within academic, policy, and practice circles by providing new and important insights that contribute to knowledge, direct future investigations, and to increase the effectiveness of research-based policy and practice. Entrepreneurial Ecosystems in Cities and Regions builds a framework for establishing a robust and sustainable concept that can help propel an understanding of how cities and regions around the world can use entrepreneurship and innovation as a catalyst for their future economic, social, and environmental development. The volume highlights the need to account for urban and regional contextual factors when determining the strength or otherwise of entrepreneurial ecosystems, and illustrates that these factors can lead to the development of entrepreneurial activity of quite a different nature across cities and regions.
