The functioning of smart city in the context of global city rankings

Purpose: This paper raises theoretical issues related to the functioning of cities that are determined as smart in order to find a better operational definition for further research. Design/methodology/approach: In search of the essence of the term, the paper refers to variety of definitions of smart city, and also to the theoretical models in operation enabling the measurement and comparison of indicators among urban areas in the different world locations. The analysis was performed on three rankings: Cities in Motion Index, Mercer Quality of Living, Arcadis The Sustainable Index. Findings: The conclusions indicate that the Smart City concept is connected with sustainable development more than to the quality of life. The city rankings concerning the highest life quality is completely different from the hierarchy of smart cities. Originality/value: The paper extends the definition of smart city and it may be valuable for researchers who develop the concept of smart city in their research.
