This paper explores current trends in Smart City (SC) initiatives through an empirical study of 70 international cities. It identifies key application domains of SC initiatives, including natural resources and energy, transport and mobility, buildings, living, government, and economy and people. The study uses a Coverage Index (CI) to measure the extent to which cities have implemented SC initiatives across these domains. The results show that the evolution of SC initiatives is heavily influenced by local context factors, such as economic development, urban structure, demographic density, and geographical location. The study also highlights the role of ICT in SC initiatives, but emphasizes that ICT is just one of many inputs, and that human capital and urban living practices are also crucial. The paper discusses the importance of understanding the relationship between SC initiatives and various contextual variables, such as economic development, technology, and environmental factors. It concludes that there is no single global model for SC development, but rather a variety of approaches that depend on local conditions. The study provides policy makers with insights into how to develop SC strategies that are appropriate for their specific contexts. The findings suggest that cities with higher economic development and demographic density are more likely to implement SC initiatives, but that there is also a need to balance technological and human capital investments to ensure sustainable and inclusive urban development. The paper also highlights the importance of considering the social and environmental impacts of SC initiatives, and the need for policies that promote innovation, human capital development, and social inclusion. The study concludes that SC initiatives should be tailored to local conditions and that there is no one-size-fits-all approach to smart city development.This paper explores current trends in Smart City (SC) initiatives through an empirical study of 70 international cities.
