Mapping the Knowledge Structure and Theoretical Foundations of Scent and Consumer Behavior Research: A Cross-Disciplinary Bibliometric Analysis
摘要
The strategic use of scent in consumer contexts has attracted increasing academic attention. However, existing research on scent-related consumer behavior (SCB) remains fragmented and lacks a coherent theoretical structure across disciplines. In this study, a cross-disciplinary bibliometric analysis of 114 SCB-related articles published as of December 31, 2024 is conducted to map the knowledge structure of the field, examine its thematic evolution over time, and compare the theoretical frameworks used across academic domains. Using co-citation and keyword co-occurrence techniques, we identify two dominant theoretical trajectories: environmental psychology and multisensory congruency. A temporal analysis reveals a shift from stimulus–response frameworks to experience-based multisensory perspectives. Disciplinary comparisons show that business research emphasizes practical applications, while psychology focuses on underlying perceptual and emotional mechanisms. Building on these insights, we further synthesize three core mechanisms by which scent influences consumer behavior: affective induction, multisensory congruency, and perceptual–cognitive integration. This study contributes a cross-disciplinary knowledge map and outlines future research directions, including theoretical integration, immersive sensory experimentation, and cross-cultural validation.
