摘要
[目的/意义]以大数据、区块链、人工智能为代表的信息技术正积极推动全球实现碳中和目标,系统分析信息技术助推碳中和的研究态势,能够为学者开展更加深入的研究提供参考。[方法/过程]基于WOS、CNKI数据库中的国际国内论文数据,采用文献计量法和知识图谱工具,从发文趋势、机构合作、作者合作、关键词聚类等方面分析信息技术助推碳中和的研究现状。[结果/结论]对比分析发现:(1)国际论文的发表数量一直稳步上升,而国内波动较大;(2)在国际论文发表过程中,中美两国的科研机构占主导地位,中科院发文量高居榜首,在机构合作方面,与国际论文发文机构相比,国内论文发文机构间的合作较为分散;(3)在作者合作方面,国内论文作者间的合作更紧密,但国际论文作者间的合作现象更普遍;(4)国际国内论文的研究主题侧重点各有不同,但都关注不同信息技术(尤其是物联网和区块链)在通信、电力等应用场景中的节能降耗解决方案研究。
[Objective/Significance] Information technology, represented by big data, blockchain, and artificial intelligence, is actively promoting the global realization of carbon neutrality. A systematic analysis of the research status of information technology facilitating carbon neutrality can provide references for scholars to carry out further research. [Method/Process] Based on international and domestic papers retrieved from WOS and CNKI, a bibliometric and knowledge mapping study has been conducted from the aspects of publishing trend, institutional cooperation, author cooperation, keyword clustering and so on. [Results/Conclusions] We found that:(1) The annual number of international papers has been increasing steadily, while the annual number of domestic papers fluctuates in relatively large margin;(2) Research institutions from China and the United States dominate the publications of international papers, and the Chinese Academy of Sciences tops the list. Comparing with the cooperations among institutions from all countries, the cooperations among institutions within China is more scattered;(3) The cooperations among authors of the domestic papers is closer than international ones, but the cooperations among the authors of the international papers is more common;(4) The common research topics between the international and domestic papers include: energy-saving and consumption-reducing solutions of different information technologies(especially the Internet of Things and blockchain) in communication, power and other application scenario.
