摘　　要：产业结构是影响能源消费的重要因素,处在不同发展阶段的区域,其产业结构演进的节能效应有所差异。根据产业结构和能源消费强度两个因子,将全国30个省(直辖市、自治区)划分为四类区域,并从中选择北京、广东、贵州、山西作为典型代表,对其1995—2007年期间产业结构演进的节能效应情况进行纵向分析,并进一步进行横向比较。研究结果表明,各类区域在产业结构的节能效应方面既有相同之处,又有所差异。相同之处表现在:能源强度都呈现出下降态势;效率因素对能源强度的影响都比结构因素的影响大;影响能源强度变化的主要部门是能耗较高的工业和交通运输邮电仓储业,这两个部门在GDP中的比重变化以及单位能耗分别决定着结构和效率因素的节能效果。差异之处表现在:能源强度的下降幅度和阶段变化不同;结构和效率因素对能源强度的影响方向和效果不同。The industry structure is the important factor affecting energy consumption. Energy saving effect of the evolution of industry structure in area at different stages of development is different. Based on the strength of two factors of industry structure and energy consumption, 30 provinces（municipalities, autonomous regions ）are divided into four types of regions; Beijing, Guangdong, Guizhou, Shanxi are chosen as typical representative, their energy-saving effect of the evolution of industry structure in 1995-2007 are longitudinally analyzed and further horizontally comprised. The results show that there are both similarities and differences of these regions. Common performance：energy intensity show a downward trend;efficiency factor＇s effect for energy intensity is larger than structure factor; two high energy consumption departments of industry and transportation affect energy intensity change, and their proportion of GDP and energy intensity respectively determine energy saving effect of structure and efficiency factor. Different performance： decrease range and stage change of energy intensity are different;effect direction and degree of structure and efficiency are different.
