Within this project we aim to explore whether, and explain how product service system (PSS) innovations impact firms’ innovation behavior. We are interested to understand whether and how PSS innovations shift firms’ innovation trajectories towards more environmentally friendly directions in order to reduce the negative externalities that result from firms’ innovation activities.

In this project PSS are considered to be integrated offerings of tangible products, intangible services and the enabling infrastructure that provide a product-unspecific functional use value to their users (e.g. delivering mobility through car- or bike-sharing solutions instead of purchasing vehicles or bikes). When operating PSS solutions commonly no ownership transfer takes place to the user, who enters into an enduring contractual relationship with the offering firm (i.e. instead of a single purchase contract as often characteristic for product sales). During the PSS use, its user becomes temporary proprietor enabling a high use-flexibility. In the project we understand firms’ innovation behavior to be predetermined by corporate strategic and specific operational R&D objectives as well as the trajectory that firms pursue in their innovation activities. Within the exploratory project phase we primarily apply case studies techniques, while in its later stages increasingly we use quantitative techniques (e.g. regression, structural equation modeling) will be used.

Project partners include colleagues at the Faculty of Agriculture and Nutritional Sciences (Kiel University), Institute for Technology and Innovation Management (Hamburg University of Technology - TUHH), Centre for Sustainability Management (Leuphana University in Lüneburg) and at the Institute for Manufacturing (University of Cambridge).
