区块链研究热点及知识结构的文献计量分析

随着数字经济时代的到来,区块链技术成为热门的研究领域.对区块链相关研究热点和知识结构进行分析,有助于厘清研究脉络,为后续研究提供参考.以中国知网(CNKI)和Web of Science(WOS)数据库收录的区块链相关文献为研究对象,采用文献计量方法对区块链相关的科研力量分布、核心作者合作网络以及关键词共现网络进行分析.论文研究发现:国外学者相比国内学者文章数量增速更快,国内外相关文献集中在计算机科学、信息技术、经济与管理科学领域;国外学者之间交流密切,合作较多,而国内学者之间尽管存在一定的交流合作,但研究团队规模较小,有待于进一步加强合作;国内相关文献高产作者和高被引作者基本匹配,国外相关文献高产作者和高被引作者失配;物联网、大数据等技术的发展推动了区块链技术的科技创新和进步;区块链相关文献知识结构与区块链技术的发展进程高度相关,是区块链1.0/2.0/3.0的体现,包括区块链技术的优化创新、数字货币、区块链金融与智能合约、区块链技术的其他应用.

Bibliometric Analysis on the Focus and Knowledge Structure of Blockchain Research

With the advent of the era of digital economy, blockchain technology has become a hot research area.The analysis of research hotspots and knowledge structure related to blockchain is helpful to clarify the research context and provide references for subsequent studies. By searching the blockchain technologyliterature based on CNKI and WOS database, this paper uses bibliometric analysis to investigate the external feature, core author collaborative network and keyword co-occurrence network of the blockchain literature. And obtain the following results: First, compared with domestic scholars, the number of foreign scholars'' articles has increased rapidly. The relevant domestic and foreign literatures are concentrated in the area of computer science, information technology, economy and management science. Second, there are more cooperation between foreign scholars, while there are some exchanges and cooperation between domestic scholars, but the research team size is small, which needs to be further strengthened. There is a obvious matching between high-productive authors and high-cited authors of CNKI database, and the obvious mismatch between high-productive authors and high-cited authors of WOS database. Third, the development of the Internet of things, big data and other technologies has promoted the technological innovation and progress of blockchain technology. Finally, the knowledge structure of blockchain-related literature is highly related to the development process of blockchain technology, which is a mapping of blockchain 1.0/2.0/3.0, including the optimization and innovation of blockchain technology, digital currency, blockchain finance and smart contract, and other application of blockchain.
