With the rapid growth of economy and the acceleration of urbanization, the problem of land use has become particularly prominent. To clarify the current research achievements and research directions in the field of land use efficiency, it is of particular significance to further enhance land use efficiency. In this study, 643 documents were obtained by searching the topic of "land use efficiency" on CNKI. The CiteSpace bibliometric tool was used to visually analyze the number of publications, authors and research hotspots. Since the 21st century, the number of documents in the field of land use efficiency has shown a fluctuating upward trend, going through three stages. There are many research hotspots on land use efficiency, which can be roughly divided into: Influential factors of land use efficiency, spatial-temporal pattern and regional differences of land use efficiency, industrial structure of land use efficiency, differences of land use efficiency in different land types, and land use efficiency under green development. The frontier of land use efficiency research in China mainly focuses on the "Yellow River Basin", "carbon emission", "intermediary effect" and "urban agglomeration".
