碳价是碳市场运行的核心,有效的价格信号可以引导资源的合理配置、激励企业转型升级以及降低社会总减排成本,因此,碳价的相关研究在国内外学术界备受关注.本研究以Web of Science(WoS)和中国知网(CNKI)数据库的 2009-2022 年4218 篇相关文献为研究对象,运用CiteSpace软件对碳价的研究现状和发展态势进行了总结和讨论,旨在为我国碳市场的健康发展提供参考和借鉴.研究表明:1)国际和国内的发文量均呈上升趋势,国际发文量相对更高,尽管我国在该领域的研究起步较晚,但发展势头最为迅猛,已经成为推动该领域快速发展的重要力量;2)WoS数据库和CNKI数据库的核心作者的研究方向和关注重点基本一致,即通过对碳价的主要影响因素和波动变化趋势进行分析,联合使用多种方法建立碳价预测模型,开展碳市场建设、定价机制和减排手段等方面的研究;3)2 个数据库的碳价研究热点稍有差异,但总体趋同,最主要的聚类分别为"碳价"和"碳市场",代表了目前碳价领域研究的 2 个主要方向;4)通过对国内外数据库文献的比较分析可知,未来需要继续推进碳交易体系的完善,拓展研究视角和研究对象,并加强对碳减排措施的深入研究.
The research hotspot and trend analysis of carbon price field based on CiteSpace
Carbon price is the core of carbon market operation.Effective price signal is capable of guiding rational resource allocation,driving transformation and upgradation of enterprises and decreasing total carbon-reduction cost.Therefore,the research related to the carbon price has received much attentions all over the world.In this study,selecting 4218 relevant literatures from 2009 to 2022 included in the Web of Science(WoS)and China Nation Knowledge Infrastructure(CNKI)as the research object,the current status and development trend of carbon price research were summarized and discussed through using CiteSpace software,aiming to provide the reference for the healthy development of China's carbon market.The obtained results demonstrated that:1)The number of international and domestic publications is on the rise,where the number of international publications is relatively higher.Despite the research of China in this field is relatively late,however,its development momentum is the most rapid,and has become an important force in promoting rapid development of this field.2)The research direction and focus of the core authors in two databases are basically the same,where the research on carbon market construction,pricing mechanism and emission reduction method is carried out through analyzing main influence factors and fluctuation trend of carbon price and jointly using various methods to establish carbon price prediction model.3)The research hotspots in the two databases are slightly different,but generally converge,with the most important two clusters being'carbon price'and'carbon market',which represent two main directions of carbon price research.4)The comparative analysis of two databases shows that the improvement of carbon trading system,the expansion of the research perspective and object,as well as the in-depth study into carbon-reduction measures needs to be made in the future.
