LITERATURE REVIEW
In an era marked by digital revolution and urbanization, smart cities have become essential for addressing the intricate problems that urban settings face.These cities maximize urban governance, promote sustainable development, and improve quality of life by using cutting-edge technology and data-driven tactics.The growing popularity of smart cities has made it necessary to provide uniform benchmarks for evaluating their progress.The research's presentation of the Data-Driven Smart City Index provides a viable method for this assessment [26]- [32].

Development of Smart Cities and Digital Revolution
Smart city research emphasizes how important digital change is for urban settings.The creation of smart cities has been heavily reliant on the usage of technology and data.A look at Table 3's data consumption highlights the importance of big data analytics, IoT adoption, and open data use in the development of smart cities. Cities that effectively use these technologies show a great deal of development in their quest to become smart cities.Furthermore, one cannot undervalue the importance of connecting infrastructure.Table 4 highlights the importance of having public Wi-Fi, 5G network coverage, and fiber internet access.These figures are often linked to higher rates of economic expansion, better living standards, and more participation from the populace [33]- [38].

Environmental Sustainability and Governance
Table 2, which explores the relationship between environmental elements and governance, shows how important effective governance is to the creation of smart cities.The Environmental Score and government Score provide light on how well cities implement sustainable practices and how effective urban government is.Studies have repeatedly shown that smart city indices tend to favor cities with robust governance systems and sustainability activities [39]-[48].

Lifestyle and Infrastructure Quality
As Table 2 illustrates, a high Quality of Life Score is a prerequisite for the establishment of smart cities. Things like healthcare, education, safety, and cultural facilities are all part of what makes life quality.By focusing on these areas, smart cities hope to draw in companies and citizens and foster urban vibrancy and economic development.Furthermore, infrastructure is a basic dimension, as seen in Table 1.Strong infrastructure is a prerequisite for smart cities since it facilitates connection and data use.

Comparative Evaluation and Takeaways
One of the main objectives of this study is comparative analysis, which is emphasized in research on smart city development.Researchers and policymakers may pinpoint areas for improvement and best practices by using the Data-Driven Smart City Index.This literature evaluation is in line with the study's research goal, which is to evaluate and compare how smart cities are developing.The information produced in the tables supplied provides important empirical support for the arguments made in this presentation.As the study progresses, we will examine the distinct features and efficacy of certain cities in order to derive significant findings that support the continuous development of smart cities.In summary, the area of smart cities is dynamic and constantly changing.When evaluating the growth of smart cities, datadriven metrics-like the Data-Driven Smart City Index-are essential because they provide insightful information on the complex interplay of these urban environments.As the role of data and digital technology in defining our urban future becomes more and more important, the study presented in this article aims to further our knowledge of smart cities and their evolution.

RESEARCH METHODOLOGY
Research Design: Using the Data-Driven Smart City Index, this study compares and evaluates the growth of smart cities using a comparative research approach.Through an exploration of the key dimensions shown in the following tables-the Digital City Development Index, Data-Driven Smart City Index Components, Data Utilization in Digital City Development, and Connectivity Infrastructure in Digital Cities-the aim is to obtain a thorough understanding of smart city development.

Data Collection
To guarantee variation in terms of geographies and phases of smart city development, a purposeful sampling strategy is used for the selection of cities. Reputable smart city databases, official publications, and completed studies are the sources of the data.These resources provide standardized measurements that make it easier to calculate the components of the Data-Driven Smart City Index.To get more information on data use and connectivity infrastructure, surveys and questionnaires may sometimes be given to enterprises, citizens, and local government agencies.

Data Analysis
The Infrastructure Score, Data Utilization Score, Connectivity Score, and Overall Score of the Digital City Development Index are all calculated using the data that has been gathered.Depending on the weights applied, the calculation for the Overall Score might change.Each component of the Data-Driven Smart City Index is examined separately in order to evaluate environmental sustainability, governance, and quality of life.Aspects of data use, such as adoption of IoT, big data analytics, and open data usage, are investigated to gain understanding of how cities use data.Indicators of the connectivity infrastructure, such as the availability of public Wi-Fi, the coverage of 5G networks, and the coverage of fiber broadband, are evaluated to comprehend the technical basis of smart city efforts.

Comparative Analysis
Using the Data-Driven Smart City Index and its components, the research does a thorough comparative analysis of the chosen cities.The study tries to uncover best practices, areas for improvement, and variables substantially contributing to a city's overall evolution into a smart city using statistical and qualitative analysis.The aim of this study is to provide policymakers, scholars, and urban planners with useful information.
