Abstract: This paper takes the 499 engineering audit-related literature from 1992 to 2020 included in the CNKI database as research object, using CiteSpace software to draw a knowledge map of related literature from the author, research institution, keywords, etc., and analyze 28 years Knowledge base, research hotspots and evolution trends in the field of domestic engineering auditing. The results show that: (1) Research institutions in the field of engineering auditing in China are relatively scattered, and there is little cooperation among scholars from different institutions, and the cooperation between institutions has shown obvious regional characteristics; (2) Engineering audit theory and the development of practice is relatively balanced. There are more cross-studies between engineering audit and other fields such as investment, management and computer, and emerging research hotspots are also relatively frontier; (3) The construction of engineering auditing informatization and digitalization has a long way to go. Related research on hot topics such as whole-process consulting, BIM, big data, and blockchain still needs to be strengthened. Based on these research results, corresponding suggestions are made.
