Contexto
What changed: Introduction of seven regional cap-and-trade emissions trading pilots across China during 2013–2014. Comparison: Non-regulated industrial firms matched on four-digit industry, pilot location, assets, employment, and baseline patenting history. Limits: Around 40% of regulated firms were too large and innovative to find valid non-ETS matches, and evaluation is limited to the initial two post-policy years.
