How far is too far? a nonlinear analysis of waste facility accessibility and sorting behavior
摘要
Effective rural domestic waste management requires not only raising awareness but also transforming residents’ daily disposal behaviors. However, existing studies have largely focused on sorting intentions and institutional incentives, with limited attention to actual disposal behavior and its psycho-spatial mechanisms. This study develops an integrated framework combining facility accessibility, behavioral perceptions, and socioeconomic characteristics. Using a mixed-method approach with Random Forest and Structural Equation Modeling, we analyze field survey data from a rural township in western China. Results indicate a significant, nonlinear association between facility accessibility and disposal behavior. Educational attainment, income level, and household structure also shape behavioral tendencies. Moreover, perceived behavioral control, subjective norms, and attitudes display differentiated pathways under varying accessibility conditions, highlighting complex interactions between physical infrastructure and psychological drivers. The study emphasizes the importance of balancing disposal convenience with residents’ perceptual experience in facility planning.
