This book focuses on an important and growing policy question: how to build sustainable regional economies. In order to address this question, Jennifer Clark puts forward the notion of working regions: places where research and design functions (regional innovation systems) and production networks (industrial districts) successfully overlap, producing both a specialized regional labor market and a potential policy model for regional resilience. This emerging emphasis on sustainable regions rather than economic growth alone extends research on learning and the innovative milieu to a broader conceptualization of embedded institutional adaptive capacities and there important case studies #xE2;#xAC;#x1C; optic photonics, medical objects and recreational equipment - are used to illustrate the book#xE2;#xAC;"s main thesis.
