A smart city has developed gradually with the evolution of services and ICT technologies to achieve sustainability. Many academic and governmental documents reference this; however, there is no existing theoretical or empirical study on the characteristics of smart city services regarding sustainability. In this sense, this study aims to clarify characteristics of Conceptually Related Smart Cities (CRSCs) services from sustainability. The methodologies adopt a matrix taxonomy to sort the previous indicators in the first step. It also utilizes a keyword analysis based on a literature review to identify the characteristics of two concepts. Three outcomes result from the steps of theoretical structures. Firstly, this study develops SSC service indicators based on the synthesis of Sustainable Smart City (SSC) and Smart City and sustainable city. The second outcome is an identification of the relation between SSC services and Conceptually Related Smart Cities. Lastly, the study clarifies the significance of citizen engagement based on the evolutionary concept by typifying service development in the lens of sustainability in CRSCs. This study is worthwhile for understanding smart city services and managing different featured smart cities from a sustainability perspective.
