At present, the global economy is showing "rebound" "differentiation""uncertainty" and other anti-globalization characteristics, and manufacturing enterprises are facing more frequent and complex market competition. Under this environment, how should Chinese manufacturing enterprises overcome the complex and changeable development environment? The answer is digital transformation. At present, relevant researches on digital transformation are in full swing in the academic circle, but there is a lack of research framework to provide comprehensive understanding for later scholars. Therefore, the literature related to the digital transformation of manufacturing enterprises was reviewed from the perspectives of research objects, research methods and research problems (mainly focusing on anthems and after-effects), the overall framework of the research on digital transformation of manufacturing enterprises was constructed, and the prospect of future research is proposed.
