Due to increasing consumption and urbanisation, urban waste management and recycling are a primary concern in Italy. Italian waste collection underwent significant reform with the introduction of a sorted collection target of 65% of total collected waste in Legislative Decree No. 152/2006. In this article, we analyse the effect of this regulatory target on the efficiency of waste collection in 275 Italian municipalities in the years 2016-2019. We estimate the coefficients of the cost efficiencies of the sorted and unsorted waste without assuming functional forms for the efficient frontier or the distribution of efficiency. Our findings suggest that municipalities that met the 65% sorted waste target demonstrated higher efficiency as costs increased, whereas those that failed to meet the target demonstrated higher inefficiency as costs increased. Strong effects emerged for population and urban economic development on the success of waste collection, whereas only marginal effects were observed for population density and city size. To improve the situation of municipalities that are not meeting the 65% target, we propose several policy measures, including 'neighbourhood solidarity'.
由于消费增长和城市化进程加快,城市垃圾管理与回收成为意大利的首要关注点。随着第152/2006号立法令引入将65%的收集垃圾进行分类收集的目标,意大利的垃圾收集经历了重大改革。在本文中,我们分析了这一监管目标对2016年至2019年期间意大利275个城市垃圾收集效率的影响。我们在不假设效率前沿的函数形式或效率分布的情况下,估算了分类垃圾和未分类垃圾的成本效率系数。我们的研究结果表明,达到65%分类垃圾目标的城市随着成本增加效率更高,而未达到该目标的城市随着成本增加效率更低。人口和城市经济发展对垃圾收集的成功产生了显著影响,而人口密度和城市规模仅产生了边际影响。为改善未达到65%目标的城市的状况,我们提出了多项政策措施,包括“邻里团结”。
