摘　　要：对区块链文献进行统计及可视化研究有助于发现区块链的研究热点、研究领域和演化趋势。在中国知网检索主题为"区块链"的核心期刊论文,获取文献1 216篇,对这些文献的发文量、发文机构、作者共现、重要文献引用情况等进行统计分析,了解区块链研究现状;利用CiteSpace进行可视化分析,从关键词、时区分布等展现区块链的研究热点和演化情况;从区块链思想、核心技术和应用领域等三个维度进行讨论。研究表明:区块链文献近年呈爆发趋势,涉及学科多样化;热点主题主要集中于智能合约、金融科技、数字货币、电子政务等领域;区块链应用已经延伸到多个学科和领域,成为下一代信息革命的主要支撑技术,促进了新兴技术的融合与发展。Statistical and visual research on blockchain literature is helpful to discover the research hotspots, research fields and evolution trends of blockchain. This paper obtains 1, 216 important papers by searching the theme of"blockchain"keywords on CNKI. First, this paper makes a statistical analysis of the number of articles published, the institutions that issued the articles, co-occurrence of authors, and citations of important documents, etc., to understand the current status of blockchain research. Second, this paper uses CiteSpace for visual analysis to show the research hotspots and evolution of blockchain in terms of keywords, time zone distribution, etc. Finally, the paper discusses the blockchain thought, core technology and application fields from three dimensions. Studies have shown that:blockchain literature has shown an explosive trend in recent years, involving a variety of disciplines;hot topics mainly focus on smart contracts,financial technology, digital currency, e-government and other fields;blockchain applications have been extending to multiple disciplines and fields, becoming the main supporting technology of the next generation of information revolution,and promoting the integration and development of emerging technologies.
