Abstract：Based on a continuous difference-in-difference model, this study evaluated the emissions reduction effect and regional variation and the mechanism of China's carbon trading pilot policies from 2004 to 2017. The results showed that the carbon trading policy could reduce the carbon intensity of the pilot areas by 9.5%, and every 1% increase in the size and activity of the carbon market brought about a 0.9% and 0.7% reduction in the carbon intensity of the pilot areas, respectively. In terms of heterogeneous impact, the carbon trading policy had a significant emission reduction effect on the east and central regions while it had no significant impact on the western areas. Further, the carbon trading policy had a significantly higher impact on carbon reduction in developed provinces than in developing provinces in China. The carbon emission reduction effect was mainly achieved by implementing influence on the enterprises participating in the market. In addition, the carbon trading policy had a synergistic pollution reduction effect, reduced sulfur dioxide emissions by 22.7% in the pilot areas. Therefore, it is necessary to accelerate the national carbon market and increase the level of carbon market activity. While it is also necessary to smooth emission reduction channels, and promote the synergistic emission reduction of carbon dioxide and other pollutants.
