Public-Private Innovation Networks in Services: Revisiting PPPs with Servitization

International audienceThis article investigates to what extent and how public-private innovation networks in services (PPINSs) can provide an original understanding of servitization-based innovations in ecosystems. To do this, we examined the biopharmaceutical industry in the Ile-de-France region in north-central France. We performed a longitudinal study from 2005 to 2016, building on structural holes and personal network efficiency methodology. Our results confirm the centrality of public actors in structuring and diffusing knowledge within a PPINS; the role of structural holes in controlling and filtering transferred knowledge, the main beneficiaries of which are private actors; and finally, the evolution and development of the PPINS around these central private/public actors. The network reveals that product-service innovation in the sector would be difficult to achieve without complex private/public interdependencies (knowledge, big data, logistics, digital therapies, etc.). Our paper also stresses on the need to move forward the public economic model from a public service into an innovative service to the public. \textcopyright 2021 Elsevier Lt
