Book excerpt: Public innovation is distinctive from private sector innovation by being set in a political system rather than a market. The roles of citizens and elected politicians as well as public servants and other stakeholders are frequently relevant. Public organizations can be creators, funders, orchestrators or sense-makers of innovations, which are carried out with the aim of benefitting society. This book provides a comprehensive insight into the theory and practice of public innovation using a wide range of research evidence about the processes, drivers and barriers, stakeholders and outcomes of innovation. Using the lens of public value, the book offers a stimulating discussion of how public innovation is valued and contested in current societies. Valuing Public Innovation aims to help develop a deeper understanding of innovation and how to use that knowledge in practical ways. This is essential reading for academics and students in the fields of innovation, organisation studies, public administration and public policy, as well as for policymakers and practitioners.
