Supplementary file 1_From environmental awareness to ecological behavior: a bibliometric mapping of the literature.docx

Lotka's Law analysis revealed that 88.94% of authors contributed only one publication, significantly exceeding the theoretical expectation of 65.47% (residual = +0.2347), signaling an active but structurally fragmented contributory base. Keyword sensitivity analysis confirmed that the thematic structure—anchored on pro-environmental behavior, attitudes, environmental attitudes, environmental concern, and sustainability—remained stable across minimum co-occurrence thresholds of ≥3, ≥5, and ≥7, demonstrating high robustness.

Thematic evolution analysis revealed three distinct developmental phases: an early foundation stage (pre-2010) dominated by knowledge and attitude frameworks, a consolidation stage (2011–2020) centered on behavioral mechanisms, and an acceleration stage (2021–2026) integrating sustainability, digital, and cross-cultural dimensions. Together, these findings suggest the field may be growing and theoretically shifting from antecedent-focused to mechanism- and application-oriented inquiry, with citation and keyword patterns appearing consistent with structural consolidation.</p>
