笔者基于中日两国非竞争型投入产出表,对1995年~2012年中日贸易内涵能源进行了测算,并运用结构分解分析(SDA)模型的加权平均分解法对影响中日内涵能源变化的因素进行了分解。测算结果表明:1995年以来,中国对日本出口内涵能源和进口内涵能源整体都呈现增长的态势,但中国一直是内涵能源净出口国。分解结果表明:出口规模的扩大和中间投入结构均促进了出口内涵能源的增加,其中出口规模的影响最为显著;直接能耗强度的下降和出口结构的优化抑制了出口内涵能源的增加,但不足以抵消出口规模所引起的内涵能源的增加。
Based on the non-competitive input-output tables of China and Japan, the author estimates the energy content of trade between China and Japan from 1995 to 2012 and uses the weighted average decomposition method of Structural Decomposition Analysis (SDA) The factor was decomposed. The calculation results show that since 1995, China has shown an increasing trend in its energy content and import energy content as a whole. However, China has always been a net exporter of energy content. Decomposition results show that: the expansion of export scale and intermediate input structure both promote the increase of energy content in export, of which the impact of export scale is the most significant; the decrease of direct energy intensity and the optimization of export structure inhibit the increase of energy content of export but not enough To offset the scale of exports caused by the increase in energy content.
