Decade of Green Innovation Research: Tracing the Intellectual Structure and Emerging Trends

Abstract

This paper analyzes 3,931 publications on green innovation (2010–2023) using VOSviewer bibliometric software. Results reveal that while China dominates publication volume, Germany and Taiwan are more frequently cited, indicating higher research impact. Thematic analysis identifies three core research clusters: eco-innovation and environmental policy; management and technological aspects of green innovation; and sustainable business models with industry applications. These clusters reflect the field's multidisciplinary nature, integrating environmental economics, corporate sustainability, and innovation management perspectives. Co-citation analysis highlights the central role of the Journal of Cleaner Production, Renewable & Sustainable Energy Reviews, and Resources, Conservation & Recycling. Temporal keyword analysis reveals a significant shift in research focus: early studies emphasized foundational concepts like eco-innovation and corporate social responsibility (CSR), while recent work prioritizes urgent issues including carbon emissions, renewable energy, and green finance. The analysis demonstrates that green innovation research increasingly emphasizes macroeconomic and
regulatory dimensions, particularly in developing countries. This work offers valuable insights for future research, identifying financial strategies, policy frameworks, and localized implementations as priority areas for investigation.
