Public–private partnerships (PPPs) are increasingly seen as a way of innovating the production and management of public services. However, the question of what drives innovation in partnerships has so far received only limited attention. Drawing on network governance and collaborative innovation literature, this article presents the findings from a survey among 260 Danish PPPs. The study shows that while innovation training has a significant effect on achieving innovation in PPPs, factors such as trust and institutional support only affect some innovation types. The findings demonstrate the importance of individual innovation skills and a differentiated understanding of innovation outcomes in PPPs.
