基于Web of Science的国际区块链技术文献计量分析

Bibliometric Analysis on International Blockchain Technology Based on Web of Science

为深入探析国际区块链领域的研究现状、研究内容与趋势,以Web of Science核心合集数据库中2223篇SCI和SSCI文献为数据源,运用CiteSpace软件对2010—2020年国际区块链领域进行了可视化分析,通过对关键词进行聚类分析,将联系紧密的关键词堆叠在一起并汇聚成不同的类别,并从年份发文情况、学科领域分布、国家和地区分布、共被引文献、关键词共现网络、关键词时区发展和关键词突现等方面绘制了知识图谱,指出国际区块链领域的研究呈现出高速发展的趋势,其主要研究集中在计算机科学、工程学、电信和商业经济等学科领域,形成了区块链技术、区块链的隐私与安全、区块链的网络体系、互联网金融领域和供应链等知识子群,研究趋势正从理论层面向实践应用层面转变。

In order to deeply analyze the research status,content and trend of the international blockchain field,this paper performs a visual analysis by taking 2223 SCI and SSCI literatures in the core collection database of Web of Science as the data sources and by using software CiteSpace,and through the cluster analysis of keywords,stacks closely related key words and aggregate them into different categories,and draws the knowledge maps from publication year,discipline domain distribution,country and region distribution,co-cited literature,keywords co-occurrence network,keywords timezone development,and keywords emergency,etc.,and points out that the research in international blockchain field shows a trend of rapid development,the main research of which focuses on computer science,engineering,telecommunications,and commercial economy,etc.,forming some knowledge subgroups such as blockchain technology,blockchain privacy and security,blockchain network system,Internet finance field,and supply chain,etc.,and the research trend is changing from the theoretical level to the practical application level.
