建筑业的发展直接影响钢铁、建材等多个高能耗经济部门,是对中国能源消耗影响最大的行业之一。基于投入产出模型和可比价投入产出表,计算了2005年、2007年以及2010年中国建筑业的完全能耗,然后结合结构分解方法分析了生产部门的直接用能强度、国民经济发展水平、中间需求、人口规模与产业结构等宏观因素对建筑业完全能耗的影响。结果表明,中国建筑业的完全能耗远高于其直接能耗;国民经济的发展、经济部门的能源利用效率等宏观因素是导致中国建筑业完全能耗不断上升的主要因素。
The construction industry has direct impacts on many high-energy consuming sectors, which is one of the most influential sectors to national energy consumption. Based on the input-output model and comparable price input-output tables, this paper analyzes impacts of the direct energy intensity, the level of economic development, intermediate demand, population and the industrial structure on the complete energy consumption by using the structural decomposition method. The results show the macro factors including economic development and energy efficiency have the most impact on complete energy consumption.
