To explore the potential effectiveness of a localized waste recycling system in Chinese cities, several rounds of a municipal solid waste source-separated collection (MSWSC) program were implemented throughout China from 2000 to 2017. In our study, to evaluate the achievements of the MSWSC program, a structured questionnaire survey and face-to-face interviews were conducted in eight representative cities from the MSWSC pilot cities. Influencing factors were examined via a Hierarchical Linear Model (HLM) on both the individual level and the city level. The differences in MSWSC performance among the eight research cities were investigated through a comparative analysis. The results suggested that gender, age, knowledge of MSWSC, satisfaction with sanitation and satisfaction with publicity had significant impacts on MSWSC, and we further found that the city-level factors influenced the relationship between MSWSC performance and the individual-level variables. Differences among the eight research sites indicated that Nanjing and Hangzhou exhibited relatively high achievements in the implementation of MSWSC program, while Yichun and Guiyang showed poor performance. The experiences of these advanced pilot cities suggest that specific containers for designated waste types, widespread public education, and sufficient MSWSC incentives must be provided and publicized to promote municipal solid waste recycling behaviors. Given the unique status of municipal solid waste management in China and its regional heterogeneity, the MSWSC system should be further discussed with regard to local conditions in a wider range of city settings. : This study attempts to discuss the factors affecting performance on municipal solid waste source-separated collection (MSWSC) by considering the nested data of two levels of individual and city from a structured questionnaire survey. Therefore, a Hierarchical Linear Model is established which can analyze the intra-group and inter-group effects of two-level variables. The proposed method can be expanded to other cities to determine the main factors affecting MSWSC or to evaluate the residents' performance on MSWSC.
为了探索中国城市本地化废物回收系统的潜在有效性，从 2000 年到 2017 年，中国各地实施了几轮城市固体废物源头分类收集（MSWSC）计划。在我们的研究中，为了评估 MSWSC 计划的成果，我们在 MSWSC 试点城市中选择了 8 个具有代表性的城市进行了结构化问卷调查和面对面访谈。通过在个体水平和城市水平上使用分层线性模型（HLM）检查了影响因素。通过比较分析研究了 8 个研究城市在 MSWSC 绩效方面的差异。结果表明，性别、年龄、对 MSWSC 的了解、对卫生的满意度和对宣传的满意度对 MSWSC 有显著影响，我们进一步发现，城市层面的因素影响了 MSWSC 绩效与个体层面变量之间的关系。8 个研究地点之间的差异表明，南京和杭州在实施 MSWSC 计划方面取得了相对较高的成就，而宜春和贵阳表现不佳。这些先进试点城市的经验表明，必须提供和宣传特定类型废物的专用容器、广泛的公众教育和充足的 MSWSC 激励措施，以促进城市固体废物回收行为。考虑到中国城市固体废物管理的独特地位及其区域性差异，应在更广泛的城市范围内，根据当地情况进一步讨论 MSWSC 系统。本研究试图通过考虑个体和城市两个层次的嵌套数据，从结构化问卷调查中考虑影响城市固体废物源头分类收集（MSWSC）绩效的因素。因此，建立了分层线性模型，可以分析两个层次变量的组内和组间效应。该方法可以扩展到其他城市，以确定影响 MSWSC 的主要因素，或评估居民对 MSWSC 的表现。
