Contexto
What changed: The Ministry of Environmental Protection launched a pilot government environmental audit in Lanzhou on February 15, 2015, supervising local government departments and polluting enterprises. Comparison: Air pollution levels before versus after the launch date using a sharp regression discontinuity design with meteorological and holiday controls. Limits: Single-city case study in a topographically enclosed basin with low dispersion; ozone pollution actually increased after the audit.
