2017年，作为落实政府制定的《大气污染防治行动计划》的一部分，中国颁布了“最严格的指挥和控制”指令，对中国主要城市的空气污染进行监管。这项研究探讨了该指令对该国公众对该国雾霾风险认知的影响。具体而言，我们通过对天津市实施条例实施前后6个月和未实施地区居民进行问卷调查，了解公众对雾霾相关风险的看法、影响其认知的因素以及认知的变化。然后对从调查中获得的面板数据进行双重差分分析。令人惊讶的是，分析表明，即使我们控制了与知识、态度、健康状况和政府治理空气污染的期望相关的因素，该指令也显着降低了公众的风险认知。这一发现建议对禁止冬季所有建筑相关活动的其他控制措施进行评估，并随后制定最佳解决方案并澄清可持续能源使用的构成。在制定政策时应考虑这种使用的外部成本。
In 2017, China enacted its “most stringent command-and-control” directive for regulating air pollution in major Chinese cities as part of the initiative to achieve the Air Pollution Prevention and Control Action Plan established by the government. This study explored the directive's effects on the public's risk perceptions of haze in the country. Specifically, we identified public views regarding haze-related risks, the factors that influence their perceptions, and the changes in such perceptions by administering questionnaires to residents of implementation and non-implementation areas in Tianjin City before and after six months–regulation application in the metropolis. The panel data obtained from the survey were then subjected to difference-in-differences analysis. Surprisingly, the analysis showed that the directive significantly reduced the public's perceptions of risk, even when we controlled for factors related to knowledge, attitudes, health conditions, and expectations from government governance of air pollution. This finding suggested that the evaluation of other control measures that prohibit all construction-related activities during winter and the subsequent formulation of optimal solution and clarification as to what constitutes sustainable energy usage. The external costs of such use should be considered in policy making.
