为了寻找有效的贸易措施来降低中国的能源消耗，并为中美气候谈判提供理论支持，我们从蕴含能源的角度研究中美贸易对能源消耗的影响。建立了环境投入产出生命周期评价（EIO-LCA）模型，计算了中美两国国民经济各部门的总能耗系数、直接能耗系数和完全能耗系数。在考虑了中美贸易中国民经济各部门的数据后，计算了中美进出口贸易中蕴含的能源，验证了中美贸易中真实的能源流动。研究结果表明：在中美贸易中，中国是隐含能源的净出口国，煤炭、原油和天然气是隐含能源的主要出口国。1997-2011年，中国实际能源净出口15238.22万吨标准煤，中国能源消费量增加89552.79万吨标准煤，美国能源消费量因中美贸易减少1187.12万吨标准煤。在此基础上，提出相应的政策建议。(C) 2014 Elsevier Ltd.版权所有。
In order to find efficient trade measures to reduce China's energy consumption and to provide theoretical support for the climate talks between China and America, we investigate the impact of Sino-USA trade on energy consumption from the perspective of embodied energy. An Environmental Input-Output Life Cycle Assessment (EIO-LCA) model was established to calculate the total energy consumption coefficient, the direct consumption coefficient and the complete consumption coefficient of the sectors of the national economies of China and America. After taking into consideration the data of every sector of the national economy in Sino-USA trade, energy embodied in the import and export trade between China and America was calculated to verify the real energy flows in Sino-USA trade. The research results suggest the following: China is the net exporter of embodied energy in Sino-USA trade, and coal, crude oil and natural gas are the major components. In 1997-2011, the net exports of China's embodied energy totaled 1523,082,200 t of standard coal, the amount of China's energy consumption increased by 895,527,900 t of standard coal, and America's energy consumption decreased by 11,871,200 t of standard coal as a result of Sino-USA trade. On this basis, corresponding policies and recommendations are proposed. (C) 2014 Elsevier Ltd. All rights reserved.
