Governments, together with partners in industry and civil society, are developing experimental forms of collaborative platforms to provide better linkages between research and innovation, and to promote the development and use of emerging technology. This report analyses 33 case studies from key fields of emerging technology – genomics, advanced materials and engineering biology – and finds that collaborative platforms are most effective when they act as “convergence spaces” for the fusion of diverse disciplines, actors and technology. It also shows how governance mechanisms shape platform operations and act as policy levers for ordering what amounts to a common pool resource: they aim to maximise tangible and intangible value, realise sustainability models, foment collaboration, and promote technological integration. After presenting cross-cutting and comparative findings on key components of governance, the report concludes with policy implications for the design of existing and future collaborative platforms.
