Abstract: This paper, based on IO-SDA, decomposes the drives of embodied energy change of Guangdong's final demand during 2002 to 2007 from economy, professions and departments, the results show that scale effect is the major drive in increasing embodied energy, technology is a key drive in decreasing energy, and economic efficiency and structural effect has a small impact. Industry, especially the heavy manufacturing plays a big part in increasing embodied energy by outputting products. A small fall in embodied energy in agricultural department, and a rise in construction by its investment effect. Consumption effect especially from urban residents is a major drive in increasing embodied energy in services. Guangdongs 2002—2007 heavy industrialization displays a high energy consumption trend, which can be resolved from technical effect, economic efficiency, and structural effect. 

Key words: embodied energy, final demand, IO-SDA, drive, Guangdong

摘要: 基于投入产出结构分解模型(IO-SDA),从经济整体、分行业、分部门3个角度对2002—2007年广东省最终需求隐含能变化的驱动因素进行了因素分解。结果显示:1)规模效应是导致广东整体及各行业最终需求隐含能增加的主要因素,技术因素则是减少隐含能消费的关键因素,经济系统效率和结构效应对隐含能变化的影响相对较小;2)工业尤其是重制造业是广东隐含能增长的主体,工业部门输出商品引致的隐含能消费是其隐含能增长的主要原因,农业部门隐含能消费小幅下降,建筑业隐含能消费的上升主要源于投资效应,服务业部门中则以消费效应尤其是城镇居民消费引致的隐含能增加占主体。研究表明,广东2002—2007年重工业化进程中呈现了“高能耗”的趋势,提高技术效应、经济系统效率及结构效应的负向作用是广东未来降低最终需求隐含能消费的着手点。
