Abstract: The blockchain technology plays an important role in new technological innovation and industrial transformation. Analysing its research status, research hotspots and development trends to provide references for the innovation and development of related industries. By obtaining relevant literature from core journals as samples, using bibliometrics and scientific knowledge graph visualization methods, the six aspects of its publication trend, source journals, core authors, interdisciplinary situation, institutions, and keywords are measured separately. The results show that blockchain research is in a period of rapid growth, and it overlaps in computer, economics and management, and social science; research resources are concentrated in famous colleges and universities, and it is not easy for ordinary universities to obtain national resources and the latest technical information; the number of cross-regional cooperation agencies is small and the frequency of cooperation is relatively small, the cooperation is relatively closed; at the technical level, research is mainly concentrated on the network layer, consensus layer, and contract layer; the application level is mainly in the financial industry and digital currency, and the application of food safety needs to be explored ; at the security level, it is necessary to strengthen the guarantee of data security and pay attention to the protection of user privacy; at the government level, a punishment mechanism should be established to deal with issues, such as threats to information security.

Key words: blockchain, bibliometric, co-occurrence analysis, research hotspots, development trends

摘要： 区块链技术发展与应用在新技术革新与产业变革中起重要作用，探究国内区块链领域研究现状、研究热点和发展趋势，为相关产业创新发展提供参考。数据选取核心期刊，利用文献计量和可视化方法，从发文趋势、来源期刊、核心作者、学科交叉情况、机构、关键词六方面分别进行计量与共现分析。结果表明，区块链研究在计算机、经济与管理科学、社会科学均有交叉；研究资源集中在少数知名院校，普通高校不易获国家资源和最新技术信息；跨地区合作机构数量较少、合作频次较少、合作较封闭；在技术层面，研究主要集中在网络层、共识层、合约层；应用层面主要在金融业与数字货币，食品安全领域应用有待挖掘；安全层面需加强保证数据安全，重视用户隐私保护；政府层面应建立惩罚机制以应对危害信息安全等问题。
