碳排放约束下能源经济效率的区域空间分布研究——基于能源消费结构门槛视角

利用2000—2012年样本数据对全要素省际能源经济效率进行了测算，研究发现样本期间绝大部分省市自治区能源经济效率整体都呈不断下降的趋势，并且生产过程中低效率地区大幅增加，分布状态由“点状”向“面状”扩散，尤其是中西部地区下降较为明显，究其原因主要为:二氧化碳排放和能源消费结构是能源经济效率变化和地区差异的重要影响因素；据此运用门槛分析方法对其进行区域空间分布研究，将全国30个省市自治区划分为低排放—结构较合理、低排放—结构欠合理、高排放—结构较合理类群、高排放—结构欠合理和高排放—结构不合理5大类群，最后结合各类型区域自身发展特点，提出因地制宜的低碳绿色发展建议，并从需求侧和供给侧两方面提出能源经济效率改善的政策建议。

Research into Regional Spatial Distribution of Energy Economy Efficiency under the Constraint of Carbon Emissions from the Perspective of Energy Consumption Structure Threshold

This paper uses DEA model to analyze the total factor energy economy efficiency of 30 provinces, municipalities, and autonomous regions in China using data from 2000 to 2012. The results indicate that the average efficiency of the overall majority of provinces in China maintains a downward trend during the research period and low efficiency regions, especially Midwest regions, increase sharply. The reasons lie in carbon emissions and energy consumption structure, because they are the important influential factors of energy economy efficiency and regional differences. Based on threshold regression method, the paper makes China be divided into five groups: the low emissions and more reasonable group, the low emissions and less reasonable group, the high emissions and more reasonable group, the high emissions and less reasonable group, and the high emissions and unreasonable group. Then, on the basis of regional development characteristics, it makes suggestions on low-carbon green development according to circumstance and energy economy efficiency improvement from the perspective of demand and supply.
