【摘要】 自2013年6月起,我国先后在深圳等七个省市实施了碳排放权交易试点。利用这一政策的"准自然实验"性质,以及基于2012—2015年上市公司平衡面板数据的双倍差分模型,实证检验了碳排放权交易对企业碳减排效果及减排机制的影响。研究发现,碳排放权交易政策的实施能有效促使企业碳减排,但企业主要是通过减少产量这种短期行为来减少碳排放,而非通过投入减排技术以达到清洁生产来实现长期减排。相关部门可通过将市场碳价维持在有效区间,为企业提供减排技术补贴等措施引导企业减排行为,以促进节能减排的技术投入,实现长期减排效果。更多还原

【Abstract】 Since June 2013,China’s central government has implemented the carbon emission trading scheme in seven provinces and cities. Exploring the"natural experiment"nature of this scheme and listed companies’ panel data from 2012-2015 and using the double difference model,this research analyzes the effect and mechanism of the carbon emission trading scheme for emission reduction by firms. The study finds that the carbon emission trading scheme reduces carbon emission,but companies reduce carbon emission mainly in a short- term manner focused on reducing production,rather than in a long-term manner that relies on abatement technology input. The findings provide theoretical support and policy suggestions for China to establish a nationwide carbon market in 2017 and to steer enterprises’ long-term emission reduction to the right direction.更多还原
