Numerous studies have examined the correlation between economic growth and air pollution, but few focuses on the nexus between environmental regulation and <2.5 μm (PM) fine particle matter. Using Spatial Durbin Model (SDM) and Spatial Two-stage Least Squares (2SLS) methods to analyze 277 Chinese cities over the period 2002-2010, this paper finds inverted U-shaped relationships between PM concentration and formal/informal environmental regulations for the whole and eastern and western regions. By removing the depression year of 2008, regulation effect on pollution strengthened, indicating that the main task for local governments in crisis is to avoid GDP decline rather than official promotion. Further, green technological innovation and industrial structure optimization induced by environmental regulation is shown to be beneficial for haze pollution mitigation. Some policy recommendations are proposed in conclusion.
许多研究都考察了经济增长与空气污染之间的相关性，但很少有研究关注环境规制与<2.5μm（PM）细颗粒物之间的关系。本文利用空间杜宾模型（SDM）和空间两阶段最小二乘法（2SLS）方法，分析了 2002-2010 年期间的 277 个中国城市，发现 PM 浓度与正式/非正式环境规制之间存在倒 U 型关系，这一关系在全国和东、西部地区均成立。去除 2008 年的萧条年后，规制对污染的影响增强，这表明地方政府在危机时期的主要任务是避免 GDP 下降，而不是追求官方政绩。此外，环境规制所带来的绿色技术创新和产业结构优化有利于缓解雾霾污染。最后提出了一些政策建议。
