Sustainable management of household solid waste (HSW) is an essential step in realizing the development of a circular economy (CE). However, for many developing countries, HSW sorting is evolving incrementally, and focusing on the intervention role of policy and the sorting behaviour of residents can help achieve sustainable waste management. This study aims to investigate the main determinants of residents' HSW sorting behaviour and how policy particularly contributes to it. Drawing upon the theory of planned behaviour (TPB) and incorporating experiences, a conceptual framework is tested on a sample of Chinese residents in Shanghai ( = 560, from November to December 2020) using structural equation modelling analysis. The empirical results show that experience and behavioural intention greatly influence HSW sorting behaviour. Moreover, the positive attitude of residents promotes the success of HSW sorting. Subjective norms and perceived behaviour control indirectly affect behavioural intention and behaviour via attitude. The findings of this study provide policymakers with critical factors for the successful implementation of HSW sorting. We also propose policy implications to maintain and improve sorting efficiency from the perspective of residents (education, communication and publicity), neighbourhood committees (degree and efficiency of supervision) and property management companies (good infrastructure, services and processes).
可持续的家庭固体废物管理（HSW）是实现循环经济（CE）发展的重要步骤。然而，对于许多发展中国家来说，HSW 分类是逐步发展的，关注政策的干预作用和居民的分类行为有助于实现可持续的废物管理。本研究旨在探讨居民 HSW 分类行为的主要决定因素，以及政策如何特别促进这一行为。本研究基于计划行为理论（TPB）并结合经验，使用结构方程模型分析方法，对上海的中国居民样本（ = 560，2020 年 11 月至 12 月）进行了检验。实证结果表明，经验和行为意图极大地影响了 HSW 分类行为。此外，居民的积极态度促进了 HSW 分类的成功。主观规范和感知行为控制通过态度间接地影响行为意图和行为。本研究的结果为政策制定者提供了成功实施 HSW 分类的关键因素。我们还从居民（教育、沟通和宣传）、居委会（监督的程度和效率）和物业管理公司（良好的基础设施、服务和流程）的角度提出了保持和提高分类效率的政策建议。
