Abstract
This study represents two critical steps forward in the area of smart city research and practice. The first is in the form of the development of a comprehensive conceptualization of smart city as a resource for researchers and government practitioners; the second is in the form of the creation of a bridge between smart cities research and practice expertise. City governments increasingly need innovative arrangements to solve a variety of technical, physical, and social problems. ``Smart city'' could be used to represent efforts that in many ways describe a vision of a city, but there is little clarity about this new concept. This paper proposes a comprehensive conceptualization of smart city, including its main components and several specific elements. Academic literature is used to create a robust framework, while a review of practical tools is used to identify specific elements or aspects not treated in the academic studies, but essential to create an integrative and comprehensive conceptualization of smart city. The paper also provides policy implications and suggests areas for future research in this topic.
