基于Citespace的国际交通基础设施研究知识图谱分析

Analysis of knowledge map on international transportation infrastructure research based on Citespace

为分析交通基础设施研究的热点与趋势,文章利用Citespace可视化软件,以2000-2021年Web of Science的SCI-E和SSCI数据库收录的交通基础设施领域文献为研究对象,进行文献外部特征及知识图谱分析。结果表明:目前研究主要聚焦于交通基础设施、交通基础设施的投资及可达性对经济增长的直接、间接影响,但研究主题具有由宏观到微观的特点;研究方向逐渐转为考虑二氧化碳排放和能源消耗的经济可持续发展。

To analyze the hot spots and trends of transportation infrastructure research.In this paper,we used Citespace visualization software to analyze the external characteristics of the literature and the knowledge map based on the literature in the field of transportation infrastructure included in the SCI-E and SSCI databases of Web of Science from 2000 to 2021.The results show that:the current research mainly focuses on the direct and indirect impacts of transportation infrastructure,transportation infrastructure investment and transportation infrastructure accessibility on economic growth.However,the theme of research has the characteristics ranging from macro to micro;the research direction has gradually shifted to sustainable economic development considering carbon dioxide emissions and energy consumption.
