Contexto
What changed: Implementation of temporary factory shutdowns, vehicle restrictions, and emission controls ahead of and during the 2016 G20 Hangzhou Summit. Comparison: Core treated cities compared against a counterfactual constructed from 49 control cities using generalized synthetic control. Limits: Combines multiple simultaneous policy measures, preventing identification of specific mechanism contributions, and potential spillover effects within the Yangtze River Delta were not modeled.
