摘要:Smart Cities (SC) have claimed to improve the quality of life of citizens, but the notion of SC is variegated and it has been changing its form. As a contribution to understand the evolutionary trends of Smart Cities, this paper analyzes the characteristics of SC programs, and the role of a set of contextual variables of SC projects adoption has been investigated. The results reveal that big innovative cities are less willing to develop SC projects, that in the building domain are driven by innovative trends and projects in the energy sector depend on the level of wealth.
