Through the application Cite Space 5.1, the Web of Science database from 1990 to 2019 and the related research literature of technological innovation audit in China and abroad are analyzed. The results show that the research of foreign technology innovation audit can be divided into theoretical research stage and practical application stage, and domestic technology innovation audit research can be divided into theoretical inspiration stage, practical exploration stage and information technology application exploration stage. It is concluded that the research direction of domestic technological innovation audit in the future can start from five aspects: constructing the theoretical framework with Chinese characteristics, broadening the research field, strengthening international cooperation, deepening the practical application of technological innovation audit in various fields, strengthening the information construction of technological innovation audit under the era of big data and establishing the information platform of innovative audit.
