In the service era, markets are reconceptualized as systems of actors interconnected through networked relationships based on resources exchange and producing value co-creation. Two of the main contemporary service research theories, Service-dominant logic and Service science, propose different organizational layouts for producing and harmonizing value co-creation: Service ecosystems and smart service systems. However, these two models show some limitations. So, this work aims at drawing an integrated model, the so called Smart service ecosystem that can be applied to hypercompetitive and experience-based sectors. The model was tested in the tourism sector by using a case study methodology. Ten interviews were administered to key informants to analyze their perception about the main dimensions of the smart service ecosystems. By adopting a holistic view, the results obtained can allow the elaboration of a framework which pinpoints: (1) the main stakeholder groups (actors); (2) the kind of resources exchanged (resource integration); (3) the tools employed (technology); (4) the institution exchange among users (institutions). Applying the model obtained to the tourism sector this work explores the main element-steps for managing and optimizing value co-creation and sustainability in the long run and thus for transitioning from innovation to social innovation.
