随着全球生产链的形成以及生产与消费活动的跨国界分隔,国际贸易的快速发展对各国的能源消耗和碳排放会产生重要影响。本文运用MRIO模型测算了1995; -2009年国际贸易中的隐含能源和碳排放。结果表明:①研究期间中国除燃气和新能源外均属于隐含能源净出口国,生产侧排放增加远超过消费侧排放增加,且; 前者增加的40%是为了满足国外需求,而消费侧排放增加仅16%来源于进口的增加;②研究期间主要发达经济体生产侧能耗和碳排放几乎没有变化,但消费侧能; 耗和碳排放却在逐渐增加,属于隐含能源和碳排放净进口国;新兴经济体的生产侧和消费侧能耗分别增加了81.7%和81.3%,且发达经济体消费引致的新兴; 经济体隐含能源和碳排放远大于后者消费引致的前者隐含能源和碳排放;③主要发达经济体的人均消费侧能耗和碳排放都远高于新兴经济体,而中国的人均消费侧能; 耗和碳排放水平都较低。With the formation of global production chains as well as cross- border; separated in production and consumption in the world, the rapid; development of international trade has an important impact on both; embodied energy and transfer emissions of trade. We estimated the; different energy consumption and emissions embodied in international; trade in 1995-2009 with the MRIO model. The results showed that:(1)China; belongs to a net exporter of embodied energy in international trade; except for new energy sources and gas during the study period; increase; of production-based emissions far exceeds the consumption-based; emissions in China, and 40% of the former is satisfied by the demands of; foreign countries, then only 16% of consumption- based emissions; increase is derived from the increase of imports;(2)The production-based; energy and carbon emissions of the major developed economies were almost; unchanged during the study period, but the consumption- based energy and; carbon emissions were gradually increasing, then they were net importers; of embodied energy and emissions in international trade; the; productionbased and consumption- based energy of emerging economies; increased by 81.7% and 81.3% respectively, and the embodied energy and; emissions of developed economies transferred into emerging economies is; much greater than the embodied energy and emissions of emerging; economies transferred into developed economies;(3)The per capita; consumption-based embodied energy and emissions in developed economies; are much higher than in emerging economies; while the per capita; embodied energy and emissions are in a low level in China.
