摘要：Motivated by the intervention of central government’s environmental protection inspection in Hebei province from January 2016 to February 2016, this paper uses a panel data method initiated by Hsiao et al. (2012) to evaluate the impact that the inspection has on air quality in 8 serious haze-capped cities of Hebei province. We find the inspection lowers 17 weeks’ average AQI in Shijiazhuang (capital of Hebei province), Tangshan, Handan, Baoding, Langfang, Cangzhou, Hengshui, and Xingtai by 13.13 (8.93%), 9.67 (7.6%), 9.6 (12.36%), 38 (16.25%), 39.73 (29.98%), 18.77 (16.2%), 4.73 (4.14%), and 17.65 (13.33%) respectively. We think an intuitive reason behind AQI’s sharp fall in Baoding and Langfang may owe to the two cities’ exactly neighboring Beijing, the capital of China, which brings them more pressure than other regions. Longer period’s average treatments for these cities are also provided, and they seem to imply a declining or even vanishing treatment effect for all cities. The environmental protection inspection may have played a role as ‘wind’: once it blows away, previously depressed polluting sources come to life again.
