基于文献计量的自然资本研究现状及热点

文章以Web of Science数据库中检索的自然资本相关文献为数据源,利用文献计量方法,分析相关文献按年份的数量变化特征、世界各国中主要研究力量和高产作者发文情况,探究目前的研究现状。之后利用Bibexcel得出高频关键词共词矩阵,导入Ucinet和NetDraw得出共现网络可视图,最后对关键词进行聚类分析。研究表明,①自然资本相关文献数量整体呈上升趋势,可大体分为萌芽发展、加速发展和成熟发展3个增长阶段;②从研究力量上看,发达国家的影响力明显强于发展中国家,美国处于遥遥领先的地位,中国起步晚,影响力较小,国际合作需要加强;③根据共词分析得出生态系统服务的价值化和可持续发展是当前的研究热点;④利用聚类分析将高频关键词分成了生态脆弱性与适应性、资本经济与自然资源、生态系统服务和资本经济管理四类。分析结果表明,未来自然资本的研究将集中于生态系统服务的价值化研究、InVEST模型的应用、绿色经济发展与区域绿色经济转型、小尺度区域服务功能价值评估及自然资本的动态评估等方面。

Status quo and hotspots of natural capital research based on bibliometrics

With the acceleration of global economic growth, the rate of people"s constant demand for the ecological environment exceeds that at which the ecological environment can provide services or resources. Thus, the global ecological environment is deteriorating. In order to inform people of the importance of the various services that ecosystems provide to humans, the value of ecosystem services, known as the natural capital, is extremely important. It is necessary to understand the current status quo and hotspots of current research on natural capital in order to facilitate further research on the topic. In this study, literature on natural capital from the Web of Science database was used the data source. This study uses bibliometrics to analyze the quantitative changes in the literature over the years, identify the main research forces and high-yield authors in the world, and explore the current research status. Then, Bibexcel software was used to obtain a co-word matrix of high-frequency keywords, and UCINET and NetDraw were imported to form the co-occurrence network view and cluster the keywords. The research shows that (1) the amount of natural capital literature is generally on the rise, and research can be roughly divided into three stages: germination development, accelerated development, and mature development. There are different emphases in the different research stages. (2) From the perspective of research strength, the influence of developed countries is obviously stronger than that of developing countries, and the United States is in a leading position. China has had a late start to this field; its influence is small, and international cooperation needs to be strengthened. (3) According to the co-word analysis, the valuation of ecosystem services and sustainable development are the current research hotspots; (4) By cluster analysis, the high-frequency keywords are divided into four categories: the vulnerability and adaptation of the ecosystem, capital economy and natural resources, ecosystem services, and capital economic management. According to the analysis results, this study speculates five possible tendencies for natural capital research: studies on valued ecosystem services, the InVEST model, development of green economy and its transformation, studies on different and small scale areas, and dynamic studies based on mathematics models. In addition, China still needs to improve its research capabilities, strengthen international cooperation, and increase its influence on research related to natural capital.
