摘　　要：本文运用"相对价格法"研究了汽油、柴油和电力等中国能源市场分割状况及其对中国全要素能源效率的影响。研究表明,中国能源市场分割呈现倒U型曲线,能源调出区市场分割情况更为严重。中国全要素能源效率呈现N型走势,能源调出区全要素能源效率更低,呈现出"能源效率诅咒"。市场分割对全要素能源效率的影响呈现U型曲线,超过97.59%的样本点表明,降低市场分割水平有利于全要素能源效率提高。据此,本文认为,推进能源市场对内开放以消除市场分割,推动合同能源管理等需求侧节能措施,降低煤炭在一次能源中的比例,提升调出区全要素能源效率,是提升中国全要素能源效率的有效途径。This paper uses the relative price method to study China′s energy market segmentation with the energy price data of various provinces and cities in China from 2004 to 2015 as an example, and uses the DEA method to investigate the efficiency of China′s energy market. Based on theoretical analysis, the influencing factors of China′s energy market efficiency are quantitatively studied. The main conclusions of the study are as follows:First, the segmentation of the Chinese market presents an inverted U-shaped curve, with a peak in 2007. The level of market segmentation remained relatively stable after 2009. The market segmentation level of energy export regions is always higher than that of energy import regions.Second, the trend of China′s total factor energy efficiency shows an "N" shape. The total factor energy efficiency of the energy import regions is significantly higher than that of the energy export regions. China has a significant "energy efficiency curse", that is, the more abundant the energy resource endowment, the lower the total factor energy efficiency of the region.Third, market segmentation is the most important factor affecting total-factor energy efficiency, and reducing the level of energy market segmentation is conducive to the improvement of total-factor energy efficiency. From a national perspective, for every 1% increase in energy market segmentation, total factor energy efficiency will drop by 4.09%. 97.59% of the sample points indicate that reducing the level of market segmentation is conducive to the improvement of total factor energy efficiency. The decline in the proportion of coal consumption in primary energy consumption is conducive to improving total factor energy efficiency.Fourth, from the perspective of the country and energy import regions, the decline of the secondary industry′s share of GDP in added value is conducive to the improvement of total factor energy efficiency, but the energy export regions are completely opposite. Based on the above conclusions, the policy r
