基于Tapio脱钩模型和Kaya恒等式,运用LMDI方法,构建了扩展的Tapio脱钩模型。选取1990-2011年中国碳排放和出口贸易的时间序列数据,对中国碳排放与出口贸易的脱钩关系进行定量分析。实证结果表明:1990-2011年期间中国碳排放与出口贸易总体呈弱脱钩关系,而16个分行业的脱钩状态存在差异;出口贸易增长与碳排放增加正相关,1990-2011年中国碳排放与出口贸易脱钩弹性指数及分解指标显示,能源结构与能源碳排放强度因素应当引起关注。
Based on Tapio decoupling model and Kaya identities, using LMDI method, the article builds an extended Tapio decou- piing model. Based on time series data of China's carbon emissions and export trade in 1990-2011. it makes a quantitative analysis of the decoupling relationship between China's carbon emissions and export trade. The results show that: the decoupling relationship be- tween China's carbon emissions and export trade is weak in the period of 1990-2011, but the decoupling relationship in 16 divisions is different. The growth of Chinese export trade is positively correlated with increased carbon emissions, carbon energy structure and ener- gy intensity factor should get more concern.
