摘要

Despite growing awareness on solid waste management, the gap between students’ intents and actual practice in waste sorting remains a major challenge, necessitating an exploration of the predictors of their intentions and the barriers to consistent behavior supporting university sustainability goals. This study examined the predictors of waste sorting intentions and behaviors among Chinese university students. This quantitative study empirically tested a proposed framework for solid waste behavior applying a cross-sectional online survey method, using convenience sampling and a closed-ended questionnaire, with 458 valid responses considered for analysis. Structural equation modeling was performed applying the SmartPLS software. The empirical findings indicate that Self-Enhancement (β = 0.260, p < 0.001), Openness to Change (β = 0.242, p < 0.001), Self-Transcendence (β = 0.148, p < 0.001), Conservation (β = 0.289, p < 0.001) are positively connected to a sense of meaning and purpose. The research findings reveal a high positive connection between a sense of meaning and purpose (β = 0.347, p < 0.001), environmental awareness (β = 0.552, p < 0.001), ascription of environmental responsibility (β = 0.363, p < 0.001), and personal norms. Personal norms (β = 0.447, p < 0.001) were also positively linked to waste sorting intentions (β = 0.726, p < 0.001), positively influencing waste sorting behavior. Additionally, trust in recycling moderated the association between waste sorting intentions and behavior (β = 0.063, p = 0.006). By incorporating new cognitive values—self-enhancement, self-transcendence, openness to change, and conservation—into the Value-Belief-Norm theory, this research provides a robust foundation for investigating relationships, aligning them with cutting-edge behavioral science paradigms. This study offers practical insights for waste management policymakers by suggesting tailored regulations and incentives aligned with individual values and personal norms.
