The intensity of household food waste is of concern throughout the world, especially, in developed countries like Australia where it accounts for 34% of all food wasted along the value chain. Due to these concerns, there has been an emergence of research over the last decade to support policy interventions. This study contributes to this body of knowledge by examining the influence of consumer shopping habits and motivational factors on the intensity of food wasted by Australian households. Based on data from an online survey of 5272 Australian households, results of this study reveal that most of the shopping habits examined (except buying food based on what is on special) have significant impacts on the intensity of food wasted. Furthermore, based on two-step cluster analysis, it was found that consumers from different backgrounds possess similar types of shopping habits, however, they are different in terms of their levels of motivations aiming to reduce food being wasted. The insights provide guidance for practitioners and policymakers regarding what actions to be taken to reduce food waste in Australian households.

澳大利亚家庭的食物浪费：购物习惯和个人动机的作用

家庭食物浪费的严重程度受到全世界的关注，特别是在像澳大利亚这样的发达国家，它占价值链上所有食物浪费的 34%。由于这些担忧，在过去十年中出现了支持政策干预的研究。本研究通过检查消费者购物习惯和动机因素对澳大利亚家庭浪费食物的强度的影响，为这一知识体系做出了贡献。根据对 5272 个澳大利亚家庭的在线调查数据，本研究的结果表明，所调查的大多数购物习惯（除了根据特价购买食物）对浪费食物的强度有显着影响。此外，基于两步聚类分析，研究发现，来自不同背景的消费者具有相似的购物习惯，但他们减少食物浪费的动机水平不同。这些见解为从业者和政策制定者提供了关于采取哪些行动来减少澳大利亚家庭食物浪费的指导。
