中国电力部门脱碳的驱动因素变化:基于碳交易机制的视角

Changes in driving factors for decarbonization in China’s power sector:A perspective based on carbon emissions trading scheme

了解中国电力部门脱碳的驱动因素以及碳交易机制在电力部门脱碳过程中所起的作用,有助于制定和完善电力部门脱碳相关政策以兑现中国对国际社会的承诺.本文基于一个自行开发的电力部门CO_(2)排放数据集,从碳交易机制实施的视角对电力部门CO_(2)排放变化的驱动因素进行分解分析,并分析这些驱动因素在碳交易机制促进电力部门脱碳过程中的作用机理.结果发现,碳交易机制实施后中国电力部门脱碳进程加快主要是由于经济增速变缓、发电结构持续优化、以及发电和用电效率逐渐提升.碳交易机制加速了中国电力部门脱碳进程,它主要是通过促进发电和用电效率提高来发挥作用的.研究结论明确了中国电力部门脱碳相关政策的优先顺序和着力点.

Understanding the driving factors of China’s power sector decarbonization and the role of carbon emissions trading scheme(ETS)in the process of power sector decarbonization can help to formulate and improve policies related to power sector decarbonization to fulfill China’s commitment to the international community.Based on a self-developed power sector CO2 emissions dataset,this study conducts a decomposition analysis of the driving factors of China’s power sector CO2 emissions changes from the perspective of ETS implementation and analyzes the mechanism of these driving factors in the process of ETS promoting decabonization in power sector.The results show that the accelerated decarbonization process of China’s power sector after the implementation of the ETS is mainly due to the slowdown in economic growth,the continuous optimization of the power generation structure,and the gradual increase in the efficiency of power generation and power consumption.The ETS has accelerated the process of decarbonization of China’s power sector,and it mainly works by promoting the efficiency of power generation and electricity consumption.The research conclusions can clarify the priority and focus of policies related to decarbonization of China’s power sector in the context of the ETS construction.
