中外碳中和领域研究现状及前景——基于CiteSpace的文献计量分析

The Current Situation and Prospects of Carbon Neutral——Bibliometric Analysis Based on CiteSpace

实现碳中和是应对全球气候变化的重要举措,国际上学者们对碳中和的研究也在持续进行。特别是对我国而言,在2020年习近平主席宣布中国力争在2060年实现碳中和后,碳中和成为国内学者的研究热点。文章以中国知网(CNKI)数据库和Web of Science(WOS)数据库中收录的碳中和相关文献为基础,运用文献计量学软件CiteSpace,对碳中和领域文献进行可视化分析。结果表明:(1)从文献发表时间与数量看,经过一段时期的探索后,文献发表量一直保持上升趋势。国内外发文主力机构是高校等科研院所,作者间发文量存在差异,大部分作者发文较少,机构间合作和作者间合作都比较多。(2)从研究主题看,中外研究出现频次较高的关键词为碳足迹、碳排放和碳中和等,研究热点可分为碳足迹的测算、低碳产业链和政策框架三个方面。(3)从主题词演变看,碳中和的研究趋势与生态保护的议题变化密切相关,国内外的研究相互影响。基于此,文章指出,未来的碳中和研究应加强多学科的交叉交融,向着多国合作的方向深入发展,注重碳补偿技术和碳交易市场研究,进一步为实现更高目标提供理论借鉴。

Achieving carbon neutrality is an important response to global climate change, and international researchers’ research on carbon neutrality is ongoing. For China in particular, carbon neutrality has become a hot topic for domestic scholars after President Xi Jinping announced in 2020 that China aims to achieve carbon neutrality by 2060. This paper selects the carbon neutral related literature collected in CNKI database and Web of Science(WOS)database as the basis, and uses the bibliometric software CiteSpace to analyze the time distribution, organization, author and keywords of carbon neutral literature. The results show that:(1)From the time and quantity of literature published, the publication of literature has maintained an upward trend after a period of exploration. The main force of sending documents at home and abroad is universities and other scientific research institutes. There are differences in the amount of papers among authors, and most authors send less papers. There is more inter agency cooperation, and there is also more cooperation among authors.(2)From the research theme, the keywords with high frequency are carbon footprint, carbon emissions and carbon neutral. The research hotspots can be divided into three aspects: carbon footprint calculation, low-carbon industrial chain and policy framework.(3)From the perspective of the evolution of the theme words, the research trend of carbon neutralization is closely related to the change of ecological protection, and the research at home and abroad influences each other. Based on this, the paper finally points out that the future carbon neutralization research should strengthen multidisciplinary cross-integration, develop in depth in the direction of multinational cooperation, attach importance to carbon compensation technology and carbon market, and further provide theoretical reference for achieving higher goals.
