Contexto
What changed: Implementation of China's Smart City Pilot policy in 2013 to promote digital governance and ICT infrastructure. Comparison: Pilot cities versus non-pilot cities before and after rollout (2011–2019). Limits: Baseline DID does not account for spatial spillovers, which spatial models suggest may shift polluting activities to neighboring cities.
