碳中和研究热点分析与展望

Hotspots analysis and prospect of carbon neutrality research

实现碳中和是应对气候问题的重要目标,现有研究缺乏对相关研究热点与演化的总结分析。本文基于文献计量分析方法,对中国知网数据库CNKI(3674篇)和外文数据库WoS核心合集(9733篇)中“碳中和”相关主题论文进行分析。研究发现:(1)CNKI高被引文献对技术方法类的研究少于WoS文献;(2)中外文献的作者在团队内部合作较多,团队间的合作略少;(3)地理位置较近的机构合作更多,中国的发文机构和发文量最多,但在影响力上不及美国等发达国家;(4)碳排放问题在两类文献中均为热点方向,CNKI文献侧重于碳排放因素分解与核算的研究,WoS文献更侧重于评估减排效果与研究技术方法。最后,对能源效率与能源转型、碳交易与碳税、隐含碳排放等方面的研究进行了展望。

Achieving carbon neutrality is an important response to climate problems,and existing studies lack a summary analysis of its hot spots and evolution.Based on Bibliometric methods,this paper analyzed the"carbon neutrality"and related topics in the core collection of Chinese database CNKI(3674 articles)and foreign database WoS(9733 articles).The findings are as follows:(1)Highly cited CNKI literature has less research on technical methods than WoS literature;(2)Authors of Chinese and foreign literature cooperate more within the team and less among the teams;(3)Institutions with closer geographic locations cooperate more.Most publishing agencies come from China with the largest number of publications,but their influence is less than that of developed countries such as the United States;(4)Carbon emission is a hot issue in both types of literature.CNKI literature focuses on the decomposition and accounting of carbon emission factors,WoS literature focuses on the assessment of emission reduction effect and technical research methods.Finally,the paper looks ahead to energy efficiency and energy transformation,carbon trading and carbon tax,implicit carbon emissions and other issues.
