Cultural Identity of the city is related to all aspects of city life，composed by rich and diverse elements. It is more like an invisible inner strength that represents the features and connotation and embodies the spirit and essence of the city rather than some visualized things such as economy，eco-environment and so on. In order to objectively present the public evaluation of cultural identities of the major cities In China，a “random telephone number dialing”（RDD）sampling method was used. 3600 respondents were invited to evaluate the cultural identities of 36 different cities，which involved eight aspects such as the historical and cultural deposits，education levels，internationalization，fashion，entertainment，food，beauties and tourism. The report comes to a conclusion by offering strategies and proposals on how to shape and improve the city image on the basis of survey analysis.
