To cope with the coronavirus disease (COVID-19), national or sub-national regions have carried out many powerful anti-pandemic measures such as locking down, which may improve their regional air quality. This paper examines the relation between regional air pollution and work resumption from a novel post-pandemic perspective. Using a unique panel dataset on China's detailed industrial electricity consumption, this paper does not find a positive relation between post-COVID-19 work resumption and regional air pollution during China's early-stage recovery. This result is obtained after controlling for province and date fixed effects, as well as local weather conditions. However, the positive relations are found in a particular sub-sample of large industrial enterprises and a particular sub-sample of April. These findings indicate that large industrial enterprises may recover first, and the resumption is progressing gradually. Finally, several policy implications are provided, which are essentially helpful for other countries' post-pandemic recovery.
为应对新型冠状病毒肺炎(COVID-19),国家或地区采取了封城等强有力的抗疫措施,这可能改善了区域空气质量。本文从后疫情时代这一新视角出发,考察了区域空气污染与复工复产之间的关系。本文利用中国详细的工业用电面板数据集,并未发现后 COVID-19 复工复产与中国经济复苏初期的区域空气污染之间存在正相关关系。这一结果是在控制了省份和日期固定效应以及当地天气条件后得出的。然而,在大型工业企业的特定子样本和 4 月份的特定子样本中发现了正相关关系。这些发现表明,大型工业企业可能率先复苏,且复工复产正在逐步推进。最后,本文提出了若干政策建议,这对其他国家的后疫情时代复苏具有借鉴意义。
