本研究は、2021～2025年のカーボンニュートラル研究の成長と構造的分化を、Web of Scienceの2,326件の文献に対する多手法計量書誌学分析により明らかにした。2023年に発表がピークに達し、用語の集中が見られた。テーマは政策、持続可能性、エネルギー転換、金融、技術革新を統合する中核と、炭素会計、環境経済学などの専門領域に分化している。地理的には中国の参加が顕著で、国際共同研究も多い。
English
This study uses a multi-method bibliometric approach on 2,326 publications to analyze the growth and structural differentiation of carbon neutrality research from 2021 to 2025. It finds that 2023 marked peak output and terminological concentration, with an integrative core linking policy, sustainability, energy transition, finance, and innovation, alongside specialized domains like carbon accounting and environmental economics. Geographically, China dominates in output and international collaboration.

📄 Abstract（原文）
Carbon neutrality research has expanded rapidly since the early 2020s, yet the 2021–2025 period has rarely been examined as a distinct phase in the field’s recent development. To address this gap, this study applies a multi-method bibliometric approach to 2,326 publications on carbon neutrality indexed in the Web of Science Core Collection, including SCI-EXPANDED and SSCI. Combining performance analysis, keyword co-occurrence analysis, Multiple Correspondence Analysis (MCA), source analysis, local citation analysis, and trend topic analysis, the study examines publication dynamics, thematic organization, geographic participation, conceptual structure, and source ecology during this period. The findings show that post-2020 growth was accompanied by increasing structural differentiation. Temporally, 2023 represents both the highest complete-year output and a point of strong terminological concentration, with core terms such as “carbon neutrality”, “CO 2 emissions”, and “emissions” occupying prominent positions. Thematically, keyword and conceptual structure analyses reveal an integrative core linking policy, sustainability, energy transition, finance, and technological innovation, alongside specialized domains related to carbon accounting, sequestration, environmental economics, materials science, and energy-system transition. Geographically, the field shows asymmetric national participation, with China combining a large domestic publication base and substantial international collaboration. Source and local citation analyses further show that productive publication venues and locally influential cited sources do not necessarily coincide. Overall, the study demonstrates that carbon neutrality research during 2021–2025 evolved from rapid expansion into a more structurally differentiated field.
