Abstract

The production of municipal solid waste (MSW) is driven by socioeconomic development and population growth. In this context, public policymakers, mainly in developing countries, are increasingly focused on ensuring sustainable production and consumption patterns through sustainable management and efficient use of resources. Because of this, we seek to contribute to the effectiveness of public policies and the role of managers in achieving the global Sustainable Development Goals 3, 6, 11, and 12. This study examines the relevance of political and contextual factors on the dynamic efficiency of the network structure of municipal solid waste services in Brazil. We used Dynamic Data Envelopment Analysis with Structure Network to calculate the overall efficiency and specific efficiency of the two proposed divisions: operational and economic. We then analyzed the effects of years in political cycles (pre-election, election year, post-election) and contextual factors (ideology, GDP, density, transfers, political size, and geography) on MSW efficiency using Generalized Estimating Equation. The dataset included longitudinal panel data from 218 MSW from 2012 to 2022. Our results showed an average efficiency score of 57.5 %, with only six MSW positioned on the efficiency frontier. Evidence of stagnation in the sector's productivity was also revealed, undermining the goals and objectives of public policies. The results suggest that the years within political cycles significantly impact sector operator efficiency before, during, and after the electoral period. Specifically, lower levels of efficiency are observed during election years, suggesting potential opportunistic behavior throughout most periods of the electoral cycle. The main contribution of this work lies in its analysis of the different periods of a political cycle, and role of capital and ideological politics in intertemporal efficiency across two divisional networks.

城市固体废物责任生产服务中的政治因素和效率:采用网络结构方法的动态 DEA
城市固体废物(MSW)的产生受到社会经济发展和人口增长的驱动。在这种情况下,主要是发展中国家的公共政策制定者越来越重视通过可持续管理和有效利用资源来确保可持续的生产和消费模式。正因为如此,我们力图促进公共政策的有效性以及管理者在实现全球可持续发展目标 3、6、11 和 12 中的作用。本研究探讨了政治和环境因素对巴西城市固体废物服务网络结构动态效率的影响。我们使用结构网络动态数据包络分析法计算了两个拟议部门(业务部门和经济部门)的总体效率和具体效率。然后,我们使用广义估计方程分析了政治周期年份(选举前、选举年、选举后)和背景因素(意识形态、GDP、密度、转移、政治规模和地理位置)对城市固体废物处理效率的影响。数据集包括从 2012 年到 2022 年 218 个澳门特别行政区的纵向面板数据。结果显示,平均效率为 57.5%,仅有六家澳门金沙线上领彩金网澳门金沙线上领彩金网处于效率前沿。我们还发现了该部门生产力停滞不前的证据,这有损于公共政策的目标和目的。研究结果表明,政治周期内的年份在选举前、选举期间和选举后都会对部门经营者的效率产生重大影响。具体而言,在选举年期间观察到的效率水平较低,这表明在选举周期的大多数时期都存在潜在的机会主义行为。这项研究的主要贡献在于分析了政治周期的不同时期,以及资本和意识形态政治在两个部门网络跨时效率中的作用。

期刊介绍: Environmental Science & Policy promotes communication among government, business and industry, academia, and non-governmental organisations who are instrumental in the solution of environmental problems. It also seeks to advance interdisciplinary research of policy relevance on environmental issues such as climate change, biodiversity, environmental pollution and wastes, renewable and non-renewable natural resources, sustainability, and the interactions among these issues. The journal emphasises the linkages between these environmental issues and social and economic issues such as production, transport, consumption, growth, demographic changes, well-being, and health. However, the subject coverage will not be restricted to these issues and the introduction of new dimensions will be encouraged.
