With the development of digital technology, in the cyber space of digital humanities in modern urban society, there is an obvious tendency of instrumentalization of technical rationality, normative value and communicative rationality, which leads to the one-dimensional living conditions of urban individuals, such as the decline of life implication, the annihilation of spiritual demands and the obscurity of subjectivity. According to Habermas' communicative action theory, only by criticizing the instrumentalization of technical rationality, criticizing the urban normative value, looking at the urban concept, and capturing the life implication of urban authors and editors, can the multidimensional perceptual existence of urbanites be reproduced, namely, the transformation from one-dimensional to multi-dimensional, the equal emphasis on instrumentality and life, the harmony between rationality and sensibility, and etc. It also includes reconstructing the multidimensional communicative dialogue behavior between urban editors and authors as well as reproducing the current urban editors and authors.
