Bibliometric Analysis of Rural Environmental Governance Research (1957–2020)

Rural environmental governance is a problem that all countries in the world will face in the process of development. The research on the related literature of Rural environmental governance is helpful to provide reference for practical work. This study uses the Aminer big data analysis platform to analyse relevant research literature on the theme of "Rural environmental governance" from 1957 to 2020. The three research perspectives are: research trends, distribution of academic achievements, and scientific research cooperation networks. The analysis results provide an overall description and judgment of the international Rural environmental governance research. 1 Research methods and research data 1.1 Research methods Most of the existing literature uses CiteSpace, VOSviewer, gephi and other software for bibliometric analysis[1-6]. There is few literature using a Aminer big data platform for research. This is also the main part that distinguishes this article from other bibliometric studies. This article adopts bibliometric research methods[7] to analyze domestic and foreign research literature on the subject of "Rural environmental governance" in three dimensions.


Research methods and research data 1.Research methods
Most of the existing literature uses CiteSpace, VOSviewer, gephi and other software for bibliometric analysis [1][2][3][4][5][6]. There is few literature using a Aminer big data platform for research. This is also the main part that distinguishes this article from other bibliometric studies. This article adopts bibliometric research methods [7] to analyze domestic and foreign research literature on the subject of "Rural environmental governance" in three dimensions.

Research data
The research data in this article comes from the Aminer big data analysis platform, the website is https://www.aminer.cn/. The specific steps are to enter the "Technical Insights" on the website, then click on the "Technical Analysis Self-Service Platform" and enter the keywords "rural management". Thus, we obtained research data. The technical analysis platform is based on Aminer's hundreds of millions of papers and scholar data, and uses massive data to achieve precise search and analysis.  Figure 1 shows that the main research countries related to Rural environmental governance are the United States, China, Australia, the United Kingdom, India, Canada, South Africa, Germany, Spain, and the Netherlands. Among them, related research in the United States was the earliest.  As can be seen in Figure 3, the representative institutions in this field are as follows: University of California, Wageningen University, University of Zimbabwe,.  The H index is a method proposed by the American physicist Jorge E. Hirsch in 2005 to evaluate the academic achievements of scholars. A mixed quantitative method is used to evaluate the academic output quantity and academic output level of scholars at the same time. It can be found from Table 1 that the H index of most scholars is below 10.

Distribution of leading institutions in various countries
As shown in Table 2 Table 3 shows the number of articles published by major research institutions, the number of scholars, and the average number of citations. Among them, the number of papers and scholars of London School of Hygiene and Tropical Medicine is not the most, but the average citation number of its papers is the highest, reaching 78.04. The situation of international cooperation can be reflected in Table 4. Country 1 is the nationality of the first author of the article, and Country 2 is the nationality of the second author and other authors. The research on Rural environmental governance in China and the United States belongs to the two countries with the most international cooperation. In second place is the cooperation between the United Kingdom and the United States. Other specific cooperation conditions can be obtained from Table 4.

conclusions
This article has studied the bibliometric issues of Rural environmental governance.
(1) The results of research trends show that: the United States first started relevant research; research hotspots include topics such as rural communities and public health; research institutions include the University of Zimbabwe, the University of Washington and so on; main research scholars include Aliya Naheed, Luca Salvati and so on..
(2) The results of distribution of research results show that: the H index of most scholars is less than 10; the main research institutions are concentrated in China, the United States and Japan; the research level is uneven.
(3) The results of the research cooperation network analysis show that there is more cooperation between China and the United States, Britain and the United States; Western Cape University and the University of Zimbabwe have more cooperation; the flow of scholars shows that the United States is a net inflow country.
