基于VOSviewer的国际虚拟水贸易研究进展

Research progress of international virtual water trade based on VOSviewer

虚拟水贸易研究是水资源可持续发展的重要研究领域。本文以Web of Science核心合集数据库的681篇虚拟水贸易文献为研究对象,对国际视阈下虚拟水贸易研究进行系统述评。采用文献计量和内容分析方法,对虚拟水贸易研究文献的年度发展规律、核心作者、主要期刊、高产国家进行梳理,并通过引文分析和关键词共现分析重点探讨了该领域的关键文章和研究热点。结果表明:虚拟水贸易的效益评价、定量研究方法、虚拟水贸易与食物贸易和气候变化的关系、水足迹在虚拟水贸易中的拓展为四大研究热点;虚拟水贸易的消极影响研究、贸易结构和贸易稳定性的评价研究、气候变化对虚拟水贸易的影响研究、定性的政策设计和定量的优化方案的结合研究等可能会成为未来虚拟水贸易研究的重点方向。

Virtual water trade research is an important field of sustainable development of water resources.In this paper,681 virtual water trade documents in the core collection database of Web of Science are taken as the research objects,and the research on virtual water trade from the international perspective is systematically reviewed.By means of bibliometrics and content analysis,this paper sorts out the annual development law,core authors,major journals and high-yielding countries of virtual water trade research literature,and focuses on the key articles and research hotspots in this field through citation analysis and key collinear analysis.The results show that:the benefit evaluation of virtual water trade,quantitative research methods,the relationship between virtual water trade and food trade and climate change,and the expansion of water footprint in virtual water trade are the four research hotspots.Studies on the negative impact of the proposed water trade,the evaluation of trade structure and trade stability,the impact of climate change on virtual water trade,and the combination of qualitative policy design and quantitative optimization schemes may become the key directions of future virtual water trade research.
