Analysis of Research Hotspots of Carbon Emission Problems in China from the Perspective of Digital Economy—Visualization and Analysis Based on CiteSpace

在全球气候治理加速转型与我国“双碳”目标纵深推进的双重背景下，针对数字经济高速发展与碳减排目标协同推进的现实需求。当前研究多聚焦单一技术或政策维度，缺乏对数字技术赋能碳治理的系统性解构与动态演进分析。本研究运用CiteSpace可视化分析工具，对中国知网(CNKI) 2015~2025年间收录的665篇有效文献进行可视化分析。通过文献计量学方法构建关键词共现网络、聚类图谱及突现词时序演化图谱，系统揭示我国数字经济驱动碳减排领域的研究热点与演进趋势。Under the dual background of accelerated transformation of global climate governance and the deepening of China’s “dual-carbon” goal, there is a need for synergizing the rapid development of the digital economy with the goal of carbon emission reduction. Current research focuses on a single technology or policy dimension, and lacks a systematic deconstruction and dynamic evolution analysis of digital technology-enabled carbon governance. In this study, we used CiteSpace visualization and analysis tool to visualize and analyze 665 effective documents included in China Knowledge Network (CNKI) during 2015~2025. The keyword co-occurrence network, cluster mapping and time-series evolution mapping of emergent words are constructed through bibliometric methods to systematically reveal the research hotspots and evolution trends in the field of digital economy-driven carbon emission reduction in China.
