The increasing rate of food waste is becoming a threat to realizing Sustainable Development goal 2 by 2030. A significant portion of food is wasted along the entire food supply chain, resulting in adverse economic, ecological and social consequences. Inferring from the norm activation model (NAM), the study investigates the influence of benefits awareness, lack of concern and personal norm on households' food waste reduction intention. Gathering research data via an online survey in Jiangsu province in China, a total sample of 408 responses were analyzed using structural equation model. It was found that the extended NAM model developed is more appropriate for assessing food waste reduction intention with a significant improved explanatory potential from 32.0 to 52.0%. Households' awareness of consequences was established to have a positive effect on ascription of responsibility, and they both impact personal norm positively. Personal norm influences food waste reduction intention positively. Again, the awareness of the benefits for reducing food waste affects households' intention to reduce food waste positively. Lack of concern for food waste negatively affects their personal norm and food waste reduction intentions. These findings furnish valuable insights for future campaigns to educate people and influence their moral norms toward the importance and involvement in achieving Sustainable Development Goals related to food waste.
食物浪费率的不断上升正威胁着到2030年实现可持续发展目标2。在整个食品供应链中，有很大一部分食物被浪费，这带来了不利的经济、生态和社会后果。基于规范激活模型（NAM），本研究调查了收益意识、缺乏关注和个人规范对家庭减少食物浪费意愿的影响。通过在中国江苏省进行的在线调查收集研究数据，使用结构方程模型对408份回复的总样本进行了分析。研究发现，所构建的扩展NAM模型更适合评估减少食物浪费的意愿，其解释力从32.0%显著提高到52.0%。家庭对后果的认知对责任归因有积极影响，且二者均对个人规范产生积极影响。个人规范对减少食物浪费的意愿有积极影响。此外，对减少食物浪费的好处的认知对家庭减少食物浪费的意愿有积极影响。对食物浪费缺乏关注会对他们的个人规范和减少食物浪费的意愿产生负面影响。这些发现为未来开展教育活动、影响人们对实现与食物浪费相关的可持续发展目标的重要性及参与度的道德规范提供了宝贵的见解。
