**5. Conclusions**

In this paper, 3550 publications related to C&D waste and the sustainable development of resources are visually analyzed using Citespace and VOSviewer, in order to identify research hotspots, research fronts, and development trends in this field. The conclusions are summarized as follows:


conducive to breaking the restriction on the circular economy and other management modes, changing the inherent thinking of stakeholders, so as to promote the green development of the construction industry and improve social benefits.

In addition, some constraints on bibliometrics methods have been found. (1) The data used in bibliometric analysis vary due to the different screening criteria of researchers. (2) Two types of visualization software may present different results. Therefore, this paper tries to use one kind of software to analyze a similar set of data. (3) The correlation between cited papers and citing papers may not be obvious in some clusters, and new technical methods should be adopted to minimize the occurrence of such problems.
