Abstract: This paper systematically sorts out the ins and outs of the concept of "modernized economic system", that is, its policy source before being proposed as an innovative policy discourse (past), the current status of related research after being proposed in the official report of the 19th National Congress of CPC (present), and research trends (future). By using the bibliometric method to analyze the relevant literature data, and the CiteSpace software to obtain the keyword co-occurrence map, we find some stylized facts, including the total amount of relevant literature and different types of literature fluctuating with time, the transformation from discourse system to academic system, and the discourse system illustrated by keyword maps, etc. The research on "modernized economic system" can be regarded as a case, which objectively shows how an innovative policy-related concept is proposed and how it is followed by the academic community.
