【摘要】 以《大气污染防治行动计划》(以下简称环境规制政策)的发布作为一次准自然实验,基于合成控制法,构造了与京津冀地区特征相似的合成控制组作为京津冀的"反事实"替身,研究了实施环境规制政策对煤炭消费量的影响,并构建双重差分模型对政策的作用机制进行检验。结果表明:环境规制政策的实施显著降低了京津冀地区的煤炭消费量,且该结果具有稳健性;环境规制政策通过优化产业结构、提高科技水平和能源效率促进地区煤炭消费量下降。更多还原

【Abstract】 Taking the publication of the action plan for the prevention and control of air pollution( hereafter referred to as environmental control policy) as a quasi-natural experiment,we build a synthetic control group with similar characteristics to the Beijing-Tianjin-Hebei Region as the counterfactual surrogate to study the influence on coal consumption and test the mechanism based on the difference-in-differences model. Results shows that, the environmental regulation policy has significantly reduced coal consumption in the Beijing-Tianjin-Hebei Region and the result is robust. Besides, the environmental control policy promotes the decline of regional coal consumption by optimizing industrial structure,improving scientific and technological level and energy efficiency.更多还原
