Contexto
What changed: Implementation of China's carbon emissions trading pilot policy starting in 2013 across designated pilot regions. Comparison: Pilot provinces versus 24 non-pilot provinces before and after policy rollout with two-way fixed effects and controls. Limits: Uses macro provincial-level panel data which obscures micro-level farm dynamics, relying on DEA-Malmquist construction.
