The growing volume of plastic waste resulting from human activities is suffocating our planet. To combat this escalating issue, this study delves into the formation of plastic reduction behavior among Swiss citizens using an extended theory of planned behavior model. Through an online survey, the study obtained 149 valid responses, which were analyzed using partial least squares-based structural equation modeling. The results indicate a significant and strong relationship between plastic risk perception and attitudes towards plastic reduction and environmental protection. Notably, the cognitive dimension (β = 0.802, p = 0.000) of plastic risk perception exhibits a tighter and stronger association with attitude compared to the emotional dimension (β = 0.406, p = 0.000). Among the three variables in the theory of planned behavior model, perceived behavioral control (β = 0.384, p = 0.000) emerges as the strongest determinant of behavioral willingness for plastic reduction. It is followed by attitude (β = 0.214, p = 0.030). However, no significant relationship is observed between subjective norm and behavioral willingness for plastic reduction (β = 0.07, p = 0.292). Finally, attitude fully mediates the relationship between plastic risk perception and behavioral willingness for plastic reduction. Theoretical and managerial implications are discussed.
人类活动产生的塑料垃圾不断增加，正在使我们的星球窒息。为了解决这一日益严重的问题，本研究采用扩展的计划行为理论模型，探讨了瑞士公民形成减少塑料行为的过程。通过在线调查，该研究获得了 149 份有效回复，并使用基于偏最小二乘的结构方程模型进行了分析。结果表明，塑料风险感知与减少塑料和保护环境的态度之间存在显著而强烈的关系。值得注意的是，与情绪维度（β=0.406，p=0.000）相比，塑料风险感知的认知维度（β=0.802，p=0.000）与态度的关联更为紧密和强烈。在计划行为理论模型的三个变量中，感知行为控制（β=0.384，p=0.000）是减少塑料行为意愿的最强决定因素。其次是态度（β=0.214，p=0.030）。然而，主观规范与减少塑料行为意愿之间没有显著关系（β=0.07，p=0.292）。最后，态度完全中介了塑料风险感知与减少塑料行为意愿之间的关系。讨论了理论和管理方面的意义。
