Abstract: Collaborative reduction of pollution and carbon dioxide is the key way to promote ecological civilization construction in China. Therefore, the analysis of domestic and foreign research hotspots and trends provides a reference for the theoretical research and practical paths of China's collaborative emission reduction governance. CiteSpace was used to sort out and analyze Chinese and English literature of WoS and CNKI, respectively, and the development trend of research in this field was explored. The results showed that the number of papers in this field was on the rise and had specific periodical differences. The United States and China had the largest number of publications, while other publications were mainly from developed countries in Europe and East Asia. In addition to more articles published in environmental science journals, foreign energy journals are more influential, while domestic economic and management journals are more influential. Foreign and domestic studies focus on strategies and policies in this field and their effect evaluation, in addition to foreign studies focusing on emission simulation and domestic studies focusing on mechanism construction in specific industries and regions. The focus of future research should be to comprehensively consider the background of regional collaborative development and the impact mechanism of multiple environmental policies, and to study the paths and policy system of collaborative reduction of pollution and carbon dioxide.
