Understanding Smart Cities: Innovation ecosystems, technological advancements, and societal challenges

Smart Cities initiatives are spreading all around the globe at a phenomenal pace. Their bold ambition is to increase the competitiveness of local communities through innovation while increasing the quality of life for its citizens through better public services and a cleaner environment. Prior research has shown contrasting views and a multitude of dimensions and approaches to look at this phenomenon. In spite of the fact that this can stimulate the debate, it lacks a systematic assessment and an integrative view. The papers in the special issue on "Understanding Smart Cities: Innovation Ecosystems, Technological Advancements, and Societal Challenges" take stock of past work and provide new insights through the lenses of a hybrid framework. Moving from these premises, we offer an overview of the topic by featuring possible linkages and thematic clusters. Then, we sketch a novel research agenda for scholars, practitioners, and policy makers who wish to engage in - and build - a critical, constructive, and conducive discourse on Smart Cities.
