Visual analysis of the research context of carbon emission reduction"based on knowledge graph
"Carbon peaking"and"carbon neutrality"are related to ecology,energy and international competition.Research on carbon emission reduction will be an important topic in China for a long time to come.Based on the China National Knowledge Infrastructure(CNKI)database,5 504 documents on carbon emission reduction in the energy industry from 2000 to 2023 were screened for visual analysis of scientific knowledge graphs.CiteSpace was used to analyze the horizontal context characteristics such as author and institutional cooperation in the field of carbon emission reduction research,as well as the vertical context characteristics such as the number of articles published,research topics and research hotspot evolution,and sort out the evolu-tion logic of research objects and research methods,with a view to providing a reference for further theoretical research and prac-tical development in the later period.It was found that universities were the main research institutions in this field,and Tianjin University,Chinese Academy of Social Sciences and Renmin University of China were the leading forces in domestic carbon e-mission reduction research.However,they did not formed a large-scale cooperation network,and there was no close cooperation among the core authors of the research.Judging from the number of articles,carbon emission reduction research could be roughly divided into silent period,slow development period and rapid growth period;The research topics were mainly the general situa-tion of carbon emission reduction,low-carbon economy,calculation of carbon emission reduction,etc.,and there was little re-search on carbon emission reduction market and price;Domestic research on carbon emission reduction presented multiple main lines.With the evolution of research hotspots,keywords such as carbon emission rights,supply chain,carbon neutrality,carbon peaking,green finance,and biomass emerged to a high degree,reflecting domestic and foreign efforts,reflecting various explora-tions of paths to achieve carbon emission reduction.
