Research Hotspots and Evolution Trends of Land Resource Assets in China—Visual Bibliometric Analysis Using CiteSpace
The expansion of China's land system reform has gradually led to the importance of land as an asset. This study aims at determining research progress as well as research frontiers. Moreover, hotspots and evolutionary trends in the area were explored. To this end, using CiteSpace software, bibliometric analysis and visualization were carried out on the China National Knowledge Infrastructure (CNKI) and Web of Science database. Accordingly, 227 articles published from 2001 to 2021 were descriptively analyzed through keywords co-occurrence analysis. Consequently, the number of published papers, high-yield authors, research institutions as well as the hotspots and evolution trends were identified. As a result, a theoretical framework for the research of land resource assets was proposed. It was demonstrated that: (1) four phases can be identified for research in land resource assets in China, including the stage of the embryonic, mitigation, high-speed development, mature and stable; (2) relatively few high-yield authors and research institutions were found to have tight cooperation and connections; (3) research intensity was closely related to national policies, and research hotspots were evolved in multiple directions, but gradually focusing on key areas such as "value accounting", "outgoing audit" and "ownership by the whole people"; (4) the content of the research suffered from shortcomings regarding discipline integration, standard unification, and diversified methods. In addition, in future research, fundamental research should be strengthened, the relevant concepts need to be scientifically defined, and the theoretical basis is required to be improved. Additionally, the construction of a unified standard for land resource asset accounting system needs to be accelerated through theoretical research. Also, empirical research was suggested to be inclined toward establishing a multi-level land resource asset assessment system. Furthermore, recommendations about "ownership by the whole people" and "trinity" land resource asset assessment in China were suggested for further research in the field. In conclusion, the present study is expected to provide a reference for the construction of a comprehensive and systematic assessment system of natural and land resource assets.
