国际区块链研究进展——基于SCI/SSCI期刊论文的内容分析

Research Progress Analysis of International Blockchain——Content Analysis Based on SCI/SSCI Journals

【目的/意义】区块链技术已成为当前工业界和学术界的研究热点,通过对国际区块链研究进展的分析,为区块链技术的进一步研究提供有益的参考指引。【方法/过程】从研究力量、研究学科、研究主题三个层面构建国际区块链研究进展分析框架,以Web of Science为数据来源,通过构建国家合作网络、计算国家研究贡献度、绘制知识吸收路径图谱、计算知识扩散强度、获取研究主题分布,揭示当前国际区块链研究进展态势。【结果/结论】结果表明,在研究力量方面,美国、英国、中国、澳大利亚是国际合作网络中的核心研究团体,而中国在国际区块链研究中的研究贡献度位居第一;在研究学科方面,计算机科学是国际区块链研究的主要知识吸收学科,也是其知识扩散的主要学科之一;在研究主题方面,国际区块链研究主要涵盖六大主题。【创新/局限】本文全面探讨了国际区块链研究中的核心研究力量、知识吸收和知识扩散情况、研究主题分布,为区块链的综述研究提供了有益补充,但研究内容的覆盖度有待进一步拓展。

【Purpose/significance】Blockchain technology has become a research hotspot in industry and academia.Through the analysis of the international blockchain research progress,it provides a useful reference guide for the further study of blockchain technology.【Method/process】The research progress analysis framework of international blockchain is constructed from three aspects:research strength,research discipline and research topic.With Web of Science as the data source,the current progress of international blockchain research is revealed through the construction of country cooperation network,calculation of national academic contribution,mapping of knowledge absorption path,calculation of knowledge diffusion intensity,and acquisition of research topic distribution.【Result/conclusion】In terms of research strength,the United States,the United Kingdom,China and Australia are the core research groups in the international cooperation network,and China's academic contribution to the international blockchain research ranks first.In terms of research disciplines,computer science is the main knowledge absorption discipline of international blockchain research,and also one of the main disciplines of knowledge diffusion.In terms of research topics,the international blockchain research topics are distributed oversix major topics.【Innovation/limitation】This paper comprehensively discusses the core research strength,knowledge absorption and knowledge diffusion,and the distribution of research topics in the international blockchain research,which provides a supplement for the review of blockchain research,but the coverage of research content needs to be further expanded.
