摘　　要：能源强度是衡量能源利用效率的重要指标,二者间呈反比关系。文章使用Refined Laspeyres指数分解模型,对1985—2005年新疆能源强度进行分解,寻求影响新疆能源强度变动的主导效应。实证结果显示,改革开放以来,新疆能源利用率进入了持续改进历程,但在全国仍处于较低的水平。但还应注意到,新疆能源强度效应主要是由工业部门能源强度改进所致,尤其是重工业部门能源强度的改进,扭转了能源利用效率提升的不利影响。因此,应大力支持重工业部门的节能技术进步,同时更应大力发展耗能较低的第三产业。Energy intensity is one of important indicator to measure energy efficiency, the lower energy intensity the higher energy efficiency. In order to find the dominant effect of energy intensity change of Xinjiang, this paper uses the index decomposition model ot Refined Laspeyres to analysis energy intensity of Xinjiang from 1985 to 2005. The result is that intensity effect is the main reason of energy efficiency improvement since the Reform and Opening Up. However the shift of industry structure had no positive impact on energy intensity changes. Energy intensity improvement of industry caused intensity effect; furthermore energy intensity improvement of heavy industry reserved the adverse impact of heavy industry weight rise on energy efficiency of industry. Therefore, we should vigorously support energy-saving technological progress in the heavy industry sector and develop the tertiary industry with lower energy consumption at the same time
