区块链研究现状、知识演进与趋势分析——基于WOS核心数据库文献的科学计量

Analysis of Current Situation,Knowledge Evolution and Trend of Blockchain Research——Scientometrics Based on the Literature of the WOS Core Database

以2013年至2021年Web of Science数据库收录的与区块链相关的文献作为研究对象,深度剖析国内外区块链领域的研究现状、研究热点和发展趋势。利用CiteSpace工具对5362篇文献及引文信息,从高产研究者、高产科研机构、高产核心期刊、研究热点和关键词方面进行定性与定量的对比可视化分析。研究发现,区块链自2015年就成为研究者追踪的信息点。围绕区块链研究的高频关键词主要为区块链、互联网、智能合约、安全性和比特币等;从其研究热点分析得到七个聚类,包括供应链、隐私、伪造药品、可再生能源、加密货币、边缘计算和物联网;按照关键词时区视图可以把区块链的发展归结为区块链的基础理论、信息安全与市场应用三个方面。七个聚类及其主要关键词以及区块链的综合应用将成为未来研究的趋势,研究丰富了区块链知识演进的历史脉络,也为区块链应用的方向提供了新的视角。

The article focuses on documents in the blockchain field from 2013 to 2021 included in the Web ofScience database are used as research objects to deeply analyze the current research status,research hotspots anddevelopment trends of the blockchain field at home and abroad.The Cite Space tool is used to conduct qualitativeand quantitative comparative visual analysis of 5362 documents and citation information from the aspects of high-yield researchers,high-yield scientific research institutions,high-yield core journals,research hotspots and key-words.The result shows that blockchain has become an information point that researchers have been tracking since2015.The research on around the topic of blockchain for the high-frequency keywords which are mainly block-chain,the internet,smart contracts,security and Bit Coin,etc.The research hotspot analysis has seven clusters,in-cluding supply chain,privacy,counterfeit medicines,renewable energy,cryptocurrency,edge computing and inter-net of things.By analying the keyword time zone view,the development of the blockchain can be attributed to thebasic theory of the blockchain,information security and market applications.The seven clusters,their main key-words and the comprehensive application of blockchain will become the trend of future research,enriching the his-torical context of the evolution of blockchain knowledge,and also providing a new perspective for the direction ofblockchain applications.
