摘要:The Smart City concept has emerged in the last decade as a fusion of ideas about how information and communication technologies could improve the functioning of cities. A new concept, that of a sustainable Smart City, is already under discussion. This article aims at analyzing the Smart City concept in Romania. The resulting advantages, but also the difficulties and obstacles that need to be confronted, are considered when becoming a Smart City. When a city wants to become smart, it must consider both the advantages and the difficulties it will face in this endeavor. This paper has been able to take into account and group the four key features of a sustainable Smart City. The authors conducted research in two parts. The first consisted of conducting a comparative analysis of the most important results of Smart City projects implemented in the four reference cities in Romania compared to London. The second, a quantitative analysis, aimed to analyze the opinions and attitudes of Romanians regarding the Smart City concept in relation to sustainability. An important finding of the study shows that over half of the respondents are familiar with the Smart City concept and 41.9% consider health as a priority for investment in technology. The authors of the article propose clearer highlighting and division of cities from the point of view of creating a Smart City.
