摘要

本研究调查了新冠肺炎疫情封锁对城市固体废物的影响。基于中国北京252个社区的每日丢弃记录的独特数据集，我们进行了差异中差估计，发现一个社区的每日生活垃圾总量减少了134.16公斤，相当于每个家庭每天至少减少0.22公斤，每个包装的生活垃圾平均重量减少了56.8%。我们考虑了一系列潜在的机制，如生活垃圾囤积、丢弃时间的变化和外出恐惧，并找到了消费模式转变与减少消费的最支持。然后，我们讨论了由于严格限制消费，封锁对减少城市生活垃圾产生的影响。我们还进行了各种异质性分析。我们的研究结果通过强调封锁对城市生活垃圾产生的影响和潜在的消费机制，对城市废物管理提出了明确的影响。

COVID-19 lockdown and municipal solid waste: evidence from the discarding records of 252 communities in China

This study investigates the impacts of the COVID-19 lockdown on municipal solid waste (MSW). Based on a unique data set of daily discarding records of 252 communities in Beijing, China, we conduct a difference-in-differences estimation and find that the total daily MSW decreased by 134.16 kg in a community, which is equivalent to at least 0.22 kg per household per day, and the average weight of MSW per package decreased by 56.8 per cent after the COVID-19 lockdown. We consider a series of potential mechanisms, such as MSW hoarding, shifts in discarding time, and fear of going out, and find the most support for consumption pattern shifts with reduced consumption. We then discuss the effect of the lockdown on the reduction of MSW generation because of the strict restriction of consumption. We also conduct various heterogeneity analyses. Our results present clear implications for municipal waste management by highlighting the effect of the lockdown on the generation of MSW and the underlying consumption mechanism.

期刊介绍： Environment and Development Economics is positioned at the intersection of environmental, resource and development economics. The Editor and Associate Editors, supported by a distinguished panel of advisors from around the world, aim to encourage submissions from researchers in the field in both developed and developing countries. The Journal is divided into two main sections, Theory and Applications, which includes regular academic papers and Policy Options, which includes papers that may be of interest to the wider policy community. Environment and Development Economics also publishes occasional Policy Fora (discussions based on a focal paper). From time to time the journal publishes special issues based on a particular theme.
