Building collaborative platforms for urban innovation: Newcastle City Futures as a quadruple helix intermediary

There is a growing academic and policy interest in the notion of using cities as 'living laboratories' to develop and test responses to the social, environmental and economic challenges present in contemporary urbanism. These living laboratories are often assumed to function through 'quadruple helix' relations between varied actors from the public, private, university and community sectors. However, empirical research that explores the real-world functioning of these arrangements is comparatively limited. This paper will help address this gap through the case of Newcastle City Futures (NCF) - a university-anchored platform for collaborative urban foresight research, public engagement and innovation. In particular, the paper will concentrate on a two-year period when NCF focused on the facilitation of innovation demonstrator projects guided by the vision of Newcastle upon Tyne developing a postindustrial future as a 'test-bed city'. Detailed empirical accounts of the development of two demonstrator projects are used to illustrate and analyse processes of cross-sectoral collaboration and engaging the public in co-design. These are used to support the conceptual argument that the presence of the quadruple helix as a form of local innovation system should not be taken as given. Instead, the collaborative relationships required for transformational interventions in the future of cities need to be actively constructed by diverse actors and supported by intermediary vehicles such as NCF.
