This paper mainly investigates whether emissions trading for pollutant permits more effective. By employing difference-in-differences method and a compressive firm-level dataset, we evaluate the impact of carbon trading system pilot cities policy on enterprises' energy-saving behavior. The findings indicate that after carbon trading system pilot cities policy, enterprises' coal consumption and coal intensity decreased by almost 34 % and 33 % respectively. The policy effect is more pronounced for larger companies and for firms in energy-intensive sectors. Moreover, the policy effect becomes stronger over time. Our results satisfy the common trend assumption. Meanwhile, the investment in equipment and output are increased, which prove emissions marketization could bring about substantial improvements in productivity.
本文主要研究污染物排放权交易是否更有效。通过采用双重差分法和一个压缩的企业层面数据集，我们评估了碳交易系统试点城市政策对企业节能行为的影响。研究结果表明，在实施碳交易系统试点城市政策后，企业的煤炭消费量和煤炭强度分别下降了近34%和33%。该政策对大公司和能源密集型行业的公司效果更为显著。此外，随着时间的推移，政策效果会变得更强。我们的结果满足共同趋势假设。同时，设备投资和产出增加，这证明排放市场化可以带来生产率的大幅提高。
