中文摘要：
单位GDP能耗反映国民经济生产和使用过程中对能源的利用效率，它的变化同整个国民经济的消费、技术进步以及经济结构的调整等密切相关，基于我国1992、1997、2002及2004年30部门能源投入占用产出表，从国民经济生产总值、能源直接消耗技术、最终需求结构和最终需求总量等因素，建立了我国单位GDP能耗的投入占用产出因素分析模型，从宏观和微观层面揭示了我国10年来单位GDP能耗变化的成因，为国家制定节能降耗的相关政策提供决策依据．
英文摘要：
Energy use per unit of GDP reflects energy efficiency in the process of production and consumption. The change of it has a strong correlation with consumption, technical advance and change of the economic structure. In this paper, we set up an input-occupancy-output factor analytical model of the energy use per unit of GDP in China. The data of the model is based on 30 sectors＇ energy input-occupancy-output table in 1992, 1997, 2002 and 2004, and this paper concluded that the total output value of national economy, the direct consumtion technique of energy, the pattern of ultimate demand and the total of final demand were the affected factors. This model revealed the reason of the change in energy use per unit of GDP of our country from both the macro and micro perspective, and provided the gist of decision about the energy conservation.
