中日商品贸易中内涵能源的分析及其政策含义

Energy embodied in Goods in China-Japan Trade:An Analysis and Policy Implications

本文基于投入产出法,从国家、部门和重点行业三个层次定量研究了中日商品贸易中的内涵能源问题。分析表明,2000-2007年中国一直是内涵能源的净出口国。对比日本同类部门,中国的部门生产倾向于更多的能源要素投入和对高能耗部门的依赖,间接反映出由生产技术特征决定的投入结构还处在较低水平。这些部门产品在出口的同时也向进口国转移了大量的内涵能源。相比贸易规模,贸易结构对于中日内涵能源进出口发挥了更为关键的作用。

Based on the input-output analysis,and from the national,sectoral and key-trade industrial levels,this paper made a quantitative study on the embodied energy in Sino-Japanese merchandise trade. The analysis showed that from 2000 to 2007,China has been a net exporter of embodied energy. Compared with the similar sectors in Japan,China's productive sectors tend to input more energy factors and to be more relied on energy-intensive sectors,reflecting the fact that its input structure which is determined by technical characteristics,is still at a low level. Along with the export of the products produced by these sectors,a large amount of embodied energy are transferd to the import country. Compared with trade volume,trade structure has played a more critical role in the import and export of embodied energy between China and Japan.
