The global sustainability paradigm, catalyzed by environmental degradation since the 1960s, has positioned green consumption as a critical strategy to reconcile economic growth with ecological preservation. While international scholarship extensively explores this field, China's unique socioeconomic trajectory---marked by rapid industrialization, centralized governance, and the ``dual carbon'' (carbon peak and neutrality) targets---necessitates a dedicated investigation into its indigenous knowledge system. Leveraging CiteSpace, this scientometric study systematically analyzes 2,793 core journal articles from the Chinese National Knowledge Infrastructure (CNKI, 1994--2024) to map the intellectual evolution of green consumption research. Key findings reveal three developmental phases: initial conceptualization (1994--2000), rapid expansion (2001--2011), and thematic stabilization (2012--2024). Cluster analyses identify dominant research foci, including green marketing, circular economy, and ecological civilization, with emerging frontiers in carbon neutrality and digital economy. Despite high scholarly output, collaboration networks exhibit sparse connectivity (density = 0.0004--0.0005), reflecting structural barriers in China's academic evaluation system that prioritizes first-author publications over interdisciplinary synergy. Methodologically, this study advances a systematic knowledge map to guide future research and policy formulation, emphasizing the synergistic potential of digital innovation and green finance in implementing sustainable consumption. The findings underscore China's policy-driven research paradigm, contrasting with Western market-centric approaches, and provide actionable insights for global sustainability governance.
