Urban Renaissance is a new stage of global urban renewal, and a transformation path for cities to realize comprehensive value. This kind of urbanization encourages the construction and growth of urban culture to activate space, activate humanistic atmosphere and stimulate innovation vitality. As a medium, public art can reflect the changes of social and cultural psychology. The development of Chinese public art in the past decades has witnessed the continuous accumulation of national confidence, and the construction goal of a “culturally confident city” in the new era has also put forward new requirements for Chinese urban public art in the “aesthetic era”. Whether it is the excavation of Chinese stories, the extensive participation of citizens or the international export of culture, all of them need the intelligent renewal of the concept of building an art city.
