基于知识图谱的区块链技术及电力行业应用分析

利用可视化分析软件，对区块链技术及其在电力行业的研究现状、研究热点、发展趋势等进行客观全面的展示与分析，为区块链的研究提供指导与参考。以Web of Science核心合集为检索对象，纳入2000—2020年发表的与区块链技术研究相关的文献，应用文献计量与可视化软件CiteSpace对作者、机构、国家、关键词、被引文献等进行可视化分析。最终纳入4349篇符合要求的文章，2016年以后成井喷式增加，中国、美国、英国、澳大利亚等诸多国家均在建立全球技术合作网络，中国在该领域的学术研究较为活跃，已出现多位发文量位列前10的高产作者。目前，电力行业的应用尚处于早期，但关注度上升很快，合计引用次数前10的文章有3篇涉及区块链技术在能源领域的应用，研究热点包括区块链技术在电动汽车、微网、能源互联网及电力市场中的应用。区块链的研究仍处于新兴阶段，但极具潜力，全球合作网络处于初步形成阶段，中国在其中的影响力需进一步提高。

Analysis on Block-chain and Its Application in Energy Industry Based on Knowledge Map

The paper conducts an objective and comprehensive analysis of the international research status， research hotspots and development trends of block-chain based on visual analysis software， and provides useful guidance and reference for the research of block-chain.  The Web of Science database was used as the search object, and the articles related to the block-chain published from 2000 to 2020 were included. Visualizing analysis of the authors, institutions, countries, key words and cited documents was conducted based on bibliometric analysis and information visualization software CiteSpace. A total of 4349 articles were eventually included, and the number of a publication increased very rapidly after 2016. China, USA, England, Australia and many other countries are building their global technology research collaboration network. The Chinese researchers are active in this field and have concurred several high-productive authors, whom entered the worldwide top 10 based on the numbers of articles. The application of block-chain in energy industry is in early stage and is heating up quickly. There are 3 articles related with application in energy industry out of the top 10 citation records. The hotspots include the application of block-chain in electric vehicles, micro-grid, energy internet and electricity market. The study of blockchain is still under development, which has strong potential. The global collaboration is also under development and China needs to enhance the influence.
