Different conceptions of city have emerged in the city studies and city construction with the development of ICT.Among them,smart city,intelligent city,digital city and digital twin city have been widely discussed and used.However,these four conceptions have aroused great ambiguities since the urban study scholars and urban builders have endowed them with different interpretations and connotations.People have no idea of the boundaries of the conceptions and their evolution.Therefore,it is necessary to make a detailed analysis of these four concep-tions and illustrate their evolution process and boundaries so as to provide references for the scholars and builders.
