Environmental Regulations and Air Pollution in India: A Reexamination
重新评估印度环境法规的有效性，用卫星再分析数据替代地面监测数据，发现空气污染趋势和政策效果评估存在显著差异，强调可靠数据对政策评估的重要性。
ABSTRACT This paper reexamines the effectiveness of environmental regulations in India, originally evaluated by Greenstone and Hanna (2014) using ground‐based monitoring data. Replacing this sparse and inconsistent data with satellite‐based reanalysis data reveals contrasting air pollution trends and notable differences in the evaluation of policies' effectiveness. The findings underscore the importance of reliable data for the accurate assessment of policy outcomes in regions with limited monitoring infrastructure.
