碳中和研究热点分析与展望.

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 (3 674 articles) and foreign database WoS (9 733 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. [ABSTRACT FROM AUTHOR]
