废弃物投入产出模型是探讨经济活动与废弃物管理之间关系的合适方法。通常探索这种关系的当代研究遵循两个主要方面：要么将最终需求作为一个整体来考虑，要么通过不同类型的社会人口指标和家庭垃圾产生来确定家庭之间的关系。然而，由于缺乏与家庭消费有关的经济和环境数据，从家庭消费d的角度应用WIO模型是复杂的，家庭消费d是最终需求d的主要组成部分。本文提出了一个新的视角，应用WIO模型来评估不同家庭消费模式与间接废物产生和处理之间的关系。这种新奇是结合联合收割机宏观和微观经济和环境数据相关的澳大利亚工业部门，不同的家庭消费模式（马赛克数据），并直接产生废物到WIO模型探索这种关系在两种情况下。结果表明，在情景一中，B05（没有孩子的夫妇，他们大部分时间都在办公室）造成的间接废物产生总量比D16（没有孩子的夫妇，他们退休后呆在家里）多99.24公斤。在情景I和情景II中，B05和D16之间的经济产出和间接废物产生差异的相关系数分别为0.9796和0.9773。敏感性分析表明，直接废物产生量在合理范围内的变化不会对主要经济活动和废物产生显著影响。这项研究提出了一个不同的家庭消费的角度来估计间接废物产生通过WIO模型提供更可靠的信息，废物管理的供应链。皇冠版权所有（C）2020由爱思唯尔有限公司发布。保留所有权利。
Waste input-output (WIO) model is a suitable method to explore the nexus between economic activities and waste management. Contemporary research that typically explores this nexus follows two main aspects: either they consider Final demand as a whole, or they identify the nexus between households, with different types of socio-demographic indicators and household waste generation. However, it is complex to apply the WIO model from the perspective of household consumptiond a major component of Final demand d because of a lack of economic and environmental data related to household consumption. This paper proposes a new perspective, applying the WIO model to assess the nexus between different patterns of household consumption and indirect waste generation and treatment. This novelty is to combine macro- and micro-economic and environmental data related to Australian industrial sectors, different patterns of household consumption (Mosaic data), and direct waste generation into the WIO model for exploring this nexus in two scenarios. Results indicate that the total amount of indirect waste generation caused by B05 (couples without children who spend the majority of their time at the office) are 99.24 kg more than that of D16 (couples without children who are retired and stay at home) for scenario I. The correlation coefficients for differences of output of economy and indirect waste generation between B05 and D16 are 0.9796 and 0.9773 in scenarios I and II, respectively. Sensitivity analysis indicates the change of the amount of direct waste generation in a reasonable range cannot dramatically affect the major economic activities and waste generation. This research suggests a different perspective of household consumption to estimate indirect waste generation through a WIO model to provide more reliable information for waste management in the supply chain.
