The construction of smart cities is an imperative trend for high-quality urban development and represents a crucial solution to various problems that afflict urbanization, such as population growth pressure, resource scarcity, environmental degradation, and economic frailty. To create a smart city, it is essential to gain a profound understanding of the evolution and experiences of urban development and have a clear grasp of the concept, emphasis, and developmental trajectory of smart cities, With the continuous improvement of technology, economy and society, the driving force of new generation informatic technologies is able to develop smart applications and establish a new and sustainable city model. Globally, many approaches are undertaking to upgrade cities as “smart”. However, despite gaining momentum in equating the term “smart” with cities, there is no “one “universally accepted model of smart cities till date. This paper reviews the theoretical construct of smart cities from the infinite and multi-dimensional definitions of smart cities to underscore its fundamental concept and implication. In addition, identified the key factors involved in the construction of the smart city projects, it is observed that smart cities as a concept have evolved from a narrow perspective of integrating innovative technology towards building intelligent infrastructure, into a more intricate urban system that calls for social and institutional participation. In addition, we propose a concise definition for smart cities: “Smart cities use digital technologies, communication technologies, and data analytics to create an efficient and effective service environment that improves urban quality of life and promotes sustainability”, and found that the construction smart cities project effect on six factors and many criterial that can use to insure implementation sustainable smart cities. Finally, Smart cities represent a promising avenue for urban development. As cities continue to grow and face increasingly complex challenges, the integration of advanced technologies and data-driven solutions can help to create more sustainable communities.
