Research Hotspots and Evolutionary Trends of Influencing Factors of Carbon Emissions at Home and Abroad—Visual Analysis Based on CiteSpace

本文基于CiteSpace文献可视化分析软件，基于中国知网(CNKI)和Web of Science数据库，对2014年至2025年5月的1225篇中文文献和197篇英文文献进行知识图谱分析，结果表明：从文献产出的时间序列特征来看，国内外关于碳排放影响因素的研究发文量呈现波动态势，在2023年达到阶段性峰值；在研究主体的合作网络方面，国内研究机构与学者间的合作密度显著低于国际水平；关键词共现与聚类分析表明，国内外研究聚焦碳排放效率、能源消费等核心主题，而国内侧重区域差异与“双碳”目标，国外关注情景分析与空间差异；通过关键词突现分析，明晰了研究热点的动态变化，“双碳”目标、碳排放效率等或将成为未来研究热点。从研究结果来看，未来应深化跨学科与跨机构协同、强化研究方法与实践应用融合以及拓展研究维度与全球治理衔接。Based on CiteSpace bibliometric analysis software, this study conducts a knowledge mapping analysis of 1,225 Chinese-language articles and 197 English-language articles on the influencing factors of carbon emissions, published between 2014 and May 2025, drawing data from CNKI and the Web of Science databases. The results show that the number of publications has experienced a fluctuating trend, with a peak in 2023. In terms of collaborative networks, cooperation among domestic institutions and scholars is significantly less intensive than that at the international level. Co-occurrence and clustering analysis of keywords reveal that both domestic and international studies focus on core topics such as carbon emission efficiency and energy consumption. However, domestic research tends to emphasize regional differences and the “dual carbon” goals, while international studies are more concerned with scenario analysis and spatial disparities. Keyword burst analysis highlights the dynamic evolution of research hotspots, indicating that themes such as the “dual carbon” goals and carbon emission efficiency are likely to become focal points of future research. Based on these findings, future studies should strengthen interdisciplinary and inter-institutional collaboration, enhance the integration of research methods with practical applications, and expand research dimensions to better align with global governance.
