在方向性距离函数的环境规制行为分析模型（DDF-AAM）框架下，文章基于malquist-luenberger生产率指数，将污染物作为负外部性的非合意产出，测算西部10省区1995—2012年有、无环境约束下的全要素能源效率，并对其影响因素通过两阶段加权最小二乘法（TSLS）进行实证分析。结果表明：（1）在有、无环境约束下，西部地区整体能源效率均呈下降趋势，各省区之间能源效率差异明显，大部分省区在环境约束下能源效率低于无环境约束下能效值。（2）各因素在有、无环境约束下对全要素能源效率作用方向和影响程度各异。在环境约束下，技术效率、技术进步、外商直接投资促进了能源效率提升，煤炭消费占比、第二产业占比、人均资本、政府干预程度的增加抑制了全要素能源效率提升。

Under the framework of the Activity Analysis Model of Environmental Directional Distance Function (DDF-AAM), this paper, based on Malmquist-Luenberger Productivity Index and treating pollu-tion as undesirable output of negative externalities, measured the total factor energy e?ciency in western region of China during 1995-2012 with or without environmental restrictions and analyzed the influencing factors by using the method of Two-stage EGLS (TSLS). The results showed that: (1) with or without environmental restrictions, the energy e?ciency presents a declining trend in whole west China and the difference is marked between the provinces and districts. The total factor energy e?ciency, however, is lower with environmental restrictions than without in most regions. (2) with or without environmental restrictions, various factors perform differently in influencing the direction and degree of the total factor energy e?ciency. Under environmental restrictions, technical e?ciency and progress and FDI could improve energy e?ciency, but the rise of the proportion of coal consumption, the share of secondary industry, the per capita capital and the government intervention would run the opposite direction.
