我国清洁能源研究热点与趋势综述OA

[Research purpose]In the context of global energy transition and the"dual carbon"goals,research on clean energy has become a central issue in promoting green economic development.Systematically reviewing the research hotspots and trends of clean energy in China not only contributes to building a theoretical framework for clean energy studies,but also provides essential references for exploring future academic directions and practical applications.[Research method]Drawing on literature data from the China National Knowledge Infrastructure(CNKI)database,this study analyzes 4473 articles related to clean energy research from 2019 to 2024.Using the CiteSpace visualization tool,it conducts an in-depth analysis focusing on the trends in publication volume,correlations among publishing institutions and authors,and keyword clustering.[Research conclusion]Firstly,the volume of publications generally shows a"single-peak fluctuation"trend.Guided by national policies,this trend can be divided into three stages:the"steady initial period"(from 2019 to 2020),the"rapid growth period"(from 2021 to 2022),and the"slowing growth period"(from 2023 to 2024).Secondly,while the range of publishing institutions is diverse,close collaborative relationships have yet to form;authors collaboration remains limited,and no dominant research group has emerged.Thirdly,research hotspots mainly focus on the definition,types,and importance of clean energy,the development status quo of related technologies,policy implementation,and changing market demands.The year 2020 marked a significant turning point,with research interests shifting from technical aspects to policy-driven approaches and integrated solutions.Fourthly,future research should emphasizes theoretical deepening,methodological expansion,and practical exploration,fostering comprehensive and systematic studies to further advance clean energy research.
