Does the low-carbon city policy make a difference? Empirical evidence of the pilot scheme in China with DEA and PSM-DID

The pilot scheme of low-carbon cities was first introduced in 2006 in China and now three rounds of over a hundred cities have been listed as pilots. There have been studies arguing that the policy has significantly reduced carbon emission in the pilot cities. However, with greater policy leverage a...
