基于改进的假设抽取模型,构建能源在行业间关联模型,分析供给侧、需求侧角度行业部门之间隐含在经济活动中能源转移效应.根据广东省的能源需求特征分析,非能源工业部门能源直接消费量最多,其中2012年消费量占总经济部门总消费量的57.2%,是社会经济生产过程是能源资源供给中的关键部门.而对行业间能源关联研究表明,能源部门、交通运输仓储及邮政业是净输出部门,而建筑业、其他服务业是能源净输入部门.农业部门、批发零售住宿餐饮供给侧与需求侧能源消费量大致持平,且在能源转移过程中与其他行业关联较小.从年际间动态变化分析,广东省能源部门供应于自身行业内部隐含能源转移增多,从2002年的8.55%升至2012年的24.67%,说明用于能源部门加工利用的能源更多,也从侧面印证了广东省能源利用更加有效与清洁.
Based on the hypothetical extraction model, this paper divided the economic activities into several types and explored the transfers of energy embodied in the inter-industry from the supply side and demand side. Taking Guangdong Province as an example, this paper built the energy linkage model, and evaluated the differences of industrial energy consumption between supply side and demand side. According to the results of characteristic analysis, there were more energy consumed in Non-Energy Industrial Sectors, which were the main contributors of the enormous industrial energy consumptions of Guangdong, accounting 57.2% of the total energy consumption of the economic activities in 2012. As for the linkage analysis, the energy industries and the transport sectors, the storage and post sectors were net energy suppliers, while the construction sectors and other service sectors were net energy demanders. The agriculture sectors and wholesale, retail trade and hotel, restaurants sectors show relatively balanced according to the supply side and demand side. From the dynamic analysis of annual changes, the proportion of embodied energy within the energy industries increased from 8.55% in 2002 to 24.67% in 2012 of the total embodied energy transferred, indicating of more efficient use of energy in Guangdong Province during last decade.
