Is Smart City going towards sustainable city ?

Smart city's conceptualizations and interventions are gaining more and more space recently, both in management literature and in city managers’ agendas. By the way, recently a new approach is acquiring relevance, namely the 'sustainable city', as a new way to approach to the resources’ management of a city and to the implementation of services, both old ones and innovative ones. In order to understand if these two topics are related from the scholars’ point of view and which are the possible connections, the authors want to perform a bibliometric analysis to investigate on the ties between smart and sustainable. The results from our investigations show that, as the labels previously examined, it is not easy to define this more recent conceptualization because it is still hard to observe it from an all-inclusive point of view
