在电力需求激增的背景下，减缓和控制温室气体排放是中国电力行业面临的巨大挑战。对电力部门能源效率和二氧化碳减排潜力的评估日益受到重视。然而，由于数据严重不足，微观层面的研究相对较少。本文利用浙江省2004年和2008年的人口普查数据，构建了一个非参数前沿面，以评估中国燃煤发电企业的能源及相关CO2排放的减排空间。应用加权罗素方向距离函数（WRDDF）构建了节能潜力指数和CO2减排潜力指数。这两个指标都描述了发电厂在能源利用和CO2排放方面的低效率水平。研究结果表明，不同企业的节能潜力和CO2减排潜力存在显著差异。我们发现，2004年大型电力企业的效率较低，但2008年大型电力企业的效率高于小型电力企业。2008年国有企业与2004年相比没有显著差异，但2008年的表现优于非国有企业。大型企业和国有企业的这种业绩变化可能是由2006年实施的“1000强企业节能行动”推动的。
In the context of soaring demand for electricity, mitigating and controlling greenhouse gas emissions is a great challenge for China's power sector. Increasing attention has been placed on the evaluation of energy efficiency and CO2abatement potential in the power sector. However, studies at the micro-level are relatively rare due to serious data limitations. This study uses the 2004 and 2008 Census data of Zhejiang province to construct a non-parametric frontier in order to assess the abatement space of energy and associated CO2emission from China's coal-fired power enterprises. A Weighted Russell Directional Distance Function (WRDDF) is applied to construct an energy-saving potential index and a CO2emission-abatement potential index. Both indicators depict the inefficiency level in terms of energy utilization and CO2emissions of electric power plants. Our results show a substantial variation of energy-saving potential and CO2abatement potential among enterprises. We find that large power enterprises are less efficient in 2004, but become more efficient than smaller enterprises in 2008. State-owned enterprises (SOE) are not significantly different in 2008 from 2004, but perform better than their non-SOE counterparts in 2008. This change in performance for large enterprises and SOE might be driven by the “top-1000 Enterprise Energy Conservation Action” that was implemented in 2006.
