Abstract
The aim of this study was to develop an integrated and innovative approach to facilitate the ranking of evaluation criteria used to assess and compare smart megacities (SMCs). The methodology used to design the approach was based on Criteria Importance through CRITIC and CODAS. In this method, the degree of importance of each item of the criteria affecting the concept of a smart city was determined by CRITIC, an objective weighting method. Then, megacities can be compared using the CODAS technique to determine the extent to which they have adopted smart city concepts. In the current study, 32 SMCs were compared in four main areas and 20 subcategories. An analysis of the order of importance given to each area found that mobility and activities (0.32) was highest, followed closely by health and safety (0.313), opportunities (0.198), and governance (0.168). The subcategories with the greatest weight were the availability of a website/application that enables citizens to easily donate surplus items (0.076), online information about traffic conditions (0.073), and online access to job opportunities (0.062). In addition, it was determined that the most successful megacities applying the smart city concept are Beijing and Hangzhou. This study has the potential to be considered a pioneer in the literature in terms of the proposed methodology for an empirical evaluation to support smart megacity planning. Its findings provide accurate, objective, and reliable data that can guide the adoption of the smart city concept. In addition, the smart features of megacities will be explored and the current situation reviewed to provide an overview of the development path.
