基于知识图谱的成渝地区双城经济圈研究综述

为了解成渝双城经济圈研究现状、研究热点和研究前沿,并为国内开展进一步的研究提供借鉴,文章选择CNKI数据库作为文献搜索引擎,采用CiteSpace5.5.R2可视化分析软件进行成渝文献时空特征分析和关键词分析。通过文献计量法主要对年度发文趋势、文献引用概况等时间分布特征以及学科分布、基金分布、作者和机构分布等空间特征进行了分析。通过关键词可视化分析,绘制关键词共现图谱、时间线图、聚类视图、时区视图及突现词分布图深度剖析文献研究热点及研究前沿。文献计量分析结果显示,成渝领域研究文献数量庞大,但持续深入研究的文献数量较少,引用情况表明该领域研究缺乏具有高认可度的文章,作者、研究机构间的合作与交流不足,尚未形成具有影响力的作者群体和机构群体。跨学科的研究文献较少,该领域研究的广度和深度都有待开发。成渝研究领域各方面投入尚且不够,相关机构应加大对此的研究投入,提高成渝研究质量。可视化分析结果表明：成渝经济圈相关研究文献的高频关键词趋于多元化,成渝经济区频次最高。根据时区线图将成渝领域的研究分为五个阶段,各阶段文献发表情况与当时政策背景相吻合,趋热性明显。突现词显示近年来成渝研究有不断细化的趋势。通过梳理文献研究背后的基本脉络,文章指出了成渝地区经济发展历程,双城经济圈研究存在的问题以及未来研究方法、研究视角和研究内容的发展方向,为成渝双城经济圈发展研究提供有益的参考。

Knowledge graph analysis on Chengdu-Chongqing Economic Circle

In order to understand the research status, hotspot and frontier of Chengdu-Chongqing Economic Circle, and provide analysis reference for further research, this paper selects CNKI database as literature search engine, and uses CiteSpace 5.5.R2 visual analysis software to analyze spatiotemporal features and keyword of Chengdu-Chongqing literatures. Through bibliometrics, this paper mainly analyzes the temporal distribution characteristics such as annual publishing trend, literature citation, and spatial characteristics such as discipline distribution, fund distribution, author and organization distribution. Through the visual analysis of keywords, it draws the co-occurrence map of keywords, time line map, clustering view, time zone view and the distribution map of emergent words to deeply analyze the research hotspots and research frontier. The results of quantitative analysis show that there are a large number of research documents in the field of Chengdu-Chongqing region. However, there is a lack of articles with high recognition in this field, the number of continuous in-depth research documents is small. The cooperation and exchange between authors and research institutions are scarce, and an influential group of authors or institutions has not yet been formed. There are few interdisciplinary research literatures, and the breadth and depth of research in this field need to be developed. In addition, the investment in all aspects of Chengdu-Chongqing area is not enough. Relevant institutions should increase the research investment to improve the research quality. The visual analysis results show that: the high-frequency keywords of relevant research literature of Chengdu-Chongqing Economic Circle tend to be diversified, and Chengdu-Chongqing economic zone is the key word with the highest frequency. According to the time zone chart, the research is divided into five stages, and the literature development of each stage is consistent with the policy background at that time. Emerging words show that in recent years, Chengdu-Chongqing research has been constantly refined. By combing the basic context behind the literature research, this paper points out the economic development process of Cheng-Chongqing region, the problems in the study of Chengdu-Chongqing Economic Circle and its development prospects, which provides a useful reference for further research.
