Abstract

Municipal solid waste (MSW) disposal leads to environmental pollution, including greenhouse gas (GHG) emissions. Waste generated by consumption is an integral part of MSW management. Based on the meta-frontier super SBM-data envelopment analysis (DEA) (MF-SSBM-DEA) model, this study evaluates the eco-efficiency of MSW management in 30 provinces in China from 2006 to 2021, especially considering the undesirable output of GHG emissions. This study compares the heterogeneity of the performance of MSW management in different regions and explores the factors that influence the differences in its efficiency. In particular, this study uses the panel Tobit model to explore the impact of upgrading household consumption on the eco-efficiency of MSW management at two levels: consumption scale (CSC) and consumption structure (CST). In addition, we examined other socioeconomic influencing factors. The results indicate that the average eco-efficiency in 2021 was 21.5% higher than in 2006. The expansion of the CSC reduces eco-efficiency, whereas the upgrading of CST improves eco-efficiency greater than the expansion of the CSC. In addition, improvements in the industrial structure and economic development (ED) contribute to the eco-efficiency of MSW management.

以排放量衡量，家庭消费升级是否会影响中国固体废物管理的生态效益？

城市固体废物（MSW）处理会导致环境污染，包括温室气体（GHG）排放。消费产生的废物是城市固体废物管理不可分割的一部分。本研究基于元前沿超级 SBM-数据包络分析（DEA）（MF-SSBM-DEA）模型，评估了中国 30 个省份 2006 年至 2021 年城市固体废物管理的生态效率，特别是考虑了温室气体排放这一不良产出。本研究比较了不同地区城市生活垃圾管理绩效的异质性，并探讨了影响其效率差异的因素。具体而言，本研究采用面板 Tobit 模型，从消费规模（CSC）和消费结构（CST）两个层面探讨了家庭消费升级对城市生活垃圾管理生态效率的影响。此外，我们还考察了其他社会经济影响因素。结果表明，2021 年的平均生态效率比 2006 年提高了 21.5%。CSC 的扩张降低了生态效率，而 CST 的升级对生态效率的改善大于 CSC 的扩张。此外，产业结构和经济发展（ED）的改善也有助于提高城市固体废物管理的生态效益。

期刊介绍： Utilities Policy is deliberately international, interdisciplinary, and intersectoral. Articles address utility trends and issues in both developed and developing economies. Authors and reviewers come from various disciplines, including economics, political science, sociology, law, finance, accounting, management, and engineering. Areas of focus include the utility and network industries providing essential electricity, natural gas, water and wastewater, solid waste, communications, broadband, postal, and public transportation services. Utilities Policy invites submissions that apply various quantitative and qualitative methods. Contributions are welcome from both established and emerging scholars as well as accomplished practitioners. Interdisciplinary, comparative, and applied works are encouraged. Submissions to the journal should have a clear focus on governance, performance, and/or analysis of public utilities with an aim toward informing the policymaking process and providing recommendations as appropriate. Relevant topics and issues include but are not limited to industry structures and ownership, market design and dynamics, economic development, resource planning, system modeling, accounting and finance, infrastructure investment, supply and demand efficiency, strategic management and productivity, network operations and integration, supply chains, adaptation and flexibility, service-quality standards, benchmarking and metrics, benefit-cost analysis, behavior and incentives, pricing and demand response, economic and environmental regulation, regulatory performance and impact, restructuring and deregulation, and policy institutions.
