摘要: 碳排放权交易政策是当前我国实现低碳经济转型的重要举措。以中国30个省级单位2007~2016年的面板数据为研究对象,从建设用地碳排放强度省际差异视角出发,运用双重差分法探究碳排放权交易政策有效性,并对该政策的作用机制进行分析。结果表明:(1)试点区与非试点区建设用地碳排放强度均值有相同的变化趋势,但试点区的碳排放强度值总体呈下降趋势,非试点区则略有上升,说明碳排放权交易政策的实施效果优于强制性减排政策;(2)双重差分法结果证实在控制其他变量的情况下,碳排放权交易政策显著降低了建设用地碳排放强度,且地均GDP、能源强度和工业结构等控制变量对建设用地碳排放强度有显著的促进作用;(3)进一步对碳排放权交易政策的作用机制检验发现,碳排放权交易政策通过对能源强度的相对下降,最终起到抑制建设用地碳排放强度的作用。

Abstract: The carbon emission right trading policy is an important measure for achieving the transformation of the low-carbon economy in China. This paper takes panel data of 30 provinces in China from 2007 to 2016 as research object. The difference-in-differences model is applied to explore the effectiveness of the carbon emission right trading policy, and the mechanism of the policy is analyzed from the perspective of inter-provincial differences in the construction land carbon emission intensity. The study shows that: (1) The average value of construction land carbon emission intensity in the pilot area and the non-pilot area has same variation trend during the study period, with the carbon emission intensity value of pilot area a general decline and the non-pilot area a slight rise, which shows that the effect of implementing the carbon emission trading policy is more effective than that of mandatory emission reduction policy. (2) The results of the difference-in-differences model confirm that carbon emission trading right policy significantly reduced the construction land carbon emission intensity under the circumstances of controlling other variables. Moreover, the control variables such as the average land GDP, energy intensity, and industrial structure have significant effects on the construction land carbon emission intensity. (3) Through further investigation of the mechanism of carbon emissions trading policy, we found that the carbon emission right trading policy will ultimately serve to curb construction land carbon emission intensity with a relative decline of energy intensity.
