中国出口贸易中的隐含碳估算

Embodied Carbon Emission in China’s Export Trade

本文基于长期动态视角,引入资本折旧最终也将转化为碳排放的概念,通过调整系数去除进口中间产品的影响,利用投入产出分析方法测算了2000-2009年中国对外贸易出口产品中的隐含碳。研究结果表明,加入世界贸易组织以来,中国出口产品中包含的碳排放占中国国内碳排放总量的比重从2000年的27%上升到2006年的43%,于2007年开始下降,2009年回落到32%。2000-2009年,出口碳排放量占国内总排放量的36%。中国出口产业仍然处于环境库兹涅茨曲线的上升阶段。除机械行业外,其他主要出口行业的单位能耗已经有非常大的降低。

Based on long-term dynamic perspective, by introducing the concept that capital depreciation will eventually translate into carbon emission, and removing the impact of imports of intermediate products through the adjustment factor, this paper uses the input-output analysis to estimate the embodied carbon in Chinese export goods between 2000 and 2009. Results of this study show that since the accession to the World Trade Organization, embodied carbon emissions in China＇ s exports increased from 27% of the total emission in 2000 to 43% in 2006, when it is a summit, and dropped to 32% in 2009. The total embodied carbon emission between 2000 and 2009 accounted for 36%. China＇ s export industry is still in the fast upswing on the environment Kuznets curve. Unit production capacity of energy consumption in China＇ S export industries, except the machine industry, experienced great improvement.
