Unlike the weighty investment in research on operating systems e.g. Windows and WPS and similar to the lighter investment in research on management tools e.g. most information systems and APPs, BIM was introduced by domestic universities at the end of the last century which had faced bottlenecks in development abroad. With the encounter of large-scale domestic infrastructure and investment, researches on BIM prevailed the entire construction industry and most polytechnics. However, some scattered, repetitive, and low-level researches of them caused great waste, and some unreasonable applications deviated from the essence of management and complicated simple problems. In recent years, researches on BIM lightweight technology have been carried out continuously to solve this aspect of the problem. The paper studies more than 270 journal articles related to BIM lightweight technology included in the database of China Knowledge Network (CNKI) in the last 10 years and some application cases to draw a knowledge map by CiteSpace software and to extract the characteristics, methods and other features of related research through adopting bibliometric analysis methods. The study also proposes suggestions for lightweight research on BIM technology applications from the perspective of management.
