Column (4) presents the empirical results after introducing both control variables and two-way fixed effects, yielding a coefficient of −0.0351.
Contexto
What changed: Implementation of China's Low-Carbon City Pilot Policy across three batches, establishing carbon targets and promoting low-carbon industrial transition. Comparison: Pilot cities versus non-pilot cities over 2008–2022 using multi-period difference-in-differences. Limits: Measures citywide average concentrations without tracking intra-urban spatial disparities.
