Sustainable entrepreneurship and entrepreneurial ecosystems research is ever evolving and this timely book stimulates further exploration, offering a research agenda and alternative approaches. Presenting new scientific evidence together with policy and other practical implications, chapters demonstrate the vibrancy and diversity of approaches in the field. Chapters on sustainable entrepreneurship analyse the circular economy, entrepreneurial decision-making logics, the drivers of eco-process innovations and strategic sustainability decision-making. Entrepreneurial ecosystems are investigated through discussion of different ecosystem orientations as factors influencing entrepreneurial behaviour. This thought-provoking book concludes with consideration of the conditions predicting entrepreneurial activity or behaviour, including family background and the growth of social and commercial SMEs. This book's up-to-date analysis and practical insight will prove invaluable to scholars and researchers in entrepreneurship as well as other business and management academics, policy-makers and practitioners.
