基于河北省1118份农户的调查数据，检验环境规制对农户参与农药包装废弃物治理行为的影响，并探讨了社会规范在二者间的中介效应。结果表明：环境规制对农户参与农药包装废弃物治理行为存在显著正向影响，在农户回收行为中激励型规制影响程度最高，而集中处置行为、社区监督行为中约束型规制作用程度更高；社会规范在环境规制对农户参与农药包装废弃物治理行为的影响中存在中介效应，描述性社会规范和命令性社会规范与环境规制形成增量组合路径，具有双向放大作用，环境规制越强的地区社会规范发挥的中介效应占比越高；异质性分析发现，不同环境规制地区、种植规模分组下农户行为具有差异性，环境规制地区、小规模组中政府的各项环境规制措施进一步提升了农户参与治理能力，非环境规制地区、中规模和大规模组中，社会规范作用有所上升，路径依赖和政策学习推动农户产生自发行为。

Based on the survey data from 1118 farmers in Hebei Province, this study examines the influence of environmental regulations on farmers’ participation in pesticide packaging waste management and explores the mediating role of social norms in this relationship. The results indicate that environmental regulations have a significant positive impact on farmers’ participation in pesticide packaging waste management. Among different regulatory approaches, incentive-based regulations exert the strongest influence on farmers’ recycling behaviors, while constraint-based regulations play a more prominent role in centralized disposal and community supervision behaviors. Furthermore, social norms serve as a mediating factor in the impact of environmental regulations on farmers’ participation in pesticide packaging waste management. Both descriptive social norms and injunctive social norms interact with environmental regulations, forming an incremental combination effect that mutually reinforces their impact. The mediating role of social norms is more pronounced in regions with stronger environmental regulations. Heterogeneity analysis reveals differences in farmers’ behaviors across regions with varying environmental regulations and farm sizes. In regions with environmental regulations and among small-scale farmers, government environmental regulation measures further enhance farmers’ participation in waste management. In contrast, in non-regulated regions and among medium-scale and large-scale farmers, the influence of social norms becomes more prominent, with path dependence and policy learning driving spontaneous waste management behaviors.
