Climate change and environmental issues caused by carbon emissions have attracted the attention of governments around the world. Drawing on the experience of the EU, China is actively developing a national carbon emissions trading market, trying to encourage emission entities to incorporate carbon emissions reduction into production and consumption decisions through carbon pricing. Is this scheme an effective market-incentivized environmental regulatory policy? Since China successively launched ETS pilots in 2013, the effectiveness of reducing carbon emissions has become one of the current focus issues. This study uses the difference-in-differences (DID) method to evaluate the impact of ETS implementation on emissions reduction and employs the Super-SBM model in data envelopment analysis (DEA) to evaluate the emission-reduction efficiency of eight ETS pilots in China. We find that the carbon trading policy has achieved emission-reduction effects in the implementation stage, and the greenness of economic growth has a significant positive impact on regional GDP. The establishment of China's unified carbon market should be coordinated with regional development. Some supporting measures for regional ecological compensation and the mitigation of regional development are yet to be adopted.
碳排放所引发的气候变化和环境问题已引起世界各国政府的关注。借鉴欧盟的经验，中国正在积极发展全国碳排放交易市场，试图通过碳定价鼓励排放实体将碳排放减少纳入生产和消费决策中。该方案是否是一项有效的市场激励型环境监管政策？自2013年中国相继启动碳排放权交易体系（ETS）试点以来，碳排放减少的有效性已成为当前的焦点问题之一。本研究采用双重差分（DID）方法评估ETS实施对减排的影响，并运用数据包络分析（DEA）中的超效率SBM模型评估中国八个ETS试点的减排效率。我们发现，碳交易政策在实施阶段已实现减排效果，经济增长的绿色程度对区域GDP有显著的正向影响。中国统一碳市场的建立应与区域发展相协调。一些区域生态补偿和缓解区域发展的配套措施尚待采用。
