摘要
在新发展阶段,“双碳”目标的提出使生产低碳化成为高质量发展的重要内容。出口贸易带来的碳转移排放加大了碳减排压力,只有不断提高出口贸易隐含碳生产率才能实现出口增长与碳减排的双赢。然而,现有文献对出口贸易隐含碳生产率的研究不足,尤其缺乏对其演变态势和增长来源的深入探究。本文利用非竞争型投入产出模型测算2002—2017年中国26个部门的出口贸易隐含碳排放量,用单位隐含碳排放的产出来表征出口贸易隐含碳生产率,进而考察其演变趋势和部门收敛性,并采用LMDI-Attribution模型对其增长来源进行分解,研究结果显示:(1)2002—2005年,中国出口贸易隐含碳生产率出现小幅下降,其后则呈持续增长态势;尽管各部门的出口贸易隐含碳生产率呈平稳上升态势,但整体水平不高,且不同部门的演变趋势也不一致;第一、三产业的各部门出口贸易隐含碳生产率相对较高(均大于0.10万元/t),而第二产业的大部分部门相对较低,尤其是制造业中的高碳密集型产业最低。(2)2002—2017年各部门出口贸易隐含碳生产率的标准差、对数离差系数以及变异系数均呈增长趋势,不存在σ收敛,但存在绝对β收敛和条件β收敛,表明低生产率部门的增速高于高生产率部门,但还未带来部门间绝对差距的缩小。(3)在样本期间,中国出口贸易隐含碳生产率的增长主要来源于技术进步带来的能源生产效率提高和内需扩大带来的生产外向度降低;各部门和产业出口贸易隐含碳生产率增长的主要来源也是能源生产效率的提高,其贡献率远大于其他因素,但不同部门和产业的增长来源及各因素的贡献大小也具有明显的差异。与现有文献相比,本文采用单要素碳生产率法对26个部门和三次产业及制造业中不同碳密集型产业的出口贸易隐含碳生产率进行测算,并分析了其部门收敛性,丰富和细化
In the new stage of development,the proposal of the“dual carbon”goal makes low-carbon production an important part of high-quality development.The carbon transfer emissions brought by export trade increase the pressure of carbon emission reduction.Only by continuously improving the embodied carbon productivity of export trade can we achieve a win-win situation between export growth and carbon emission reduction.However,the existing literature on the embodied carbon productivity of export trade is insufficient,especially a lack of in-depth exploration of its evolution and sources of growth.This paper uses a non-competitive input-output model to measure the embodied carbon emissions of China′s export trade in 26 sectors from 2002 to 2017,uses the output of unit embodied carbon emissions to characterize the embodied carbon productivity of export trade,examines its evolution trend and sector convergence,and uses the LMDI-Attribution model to decompose its growth sources.The research results show that:(1)from 2002 to 2005,the embodied carbon productivity of China′s export trade decreased slightly,and then continued to grow steadily;although the embodied carbon productivity of export trade in various sectors has shown a steady upward trend,the overall level is not high,and the evolution trend of different sectors is also inconsistent;the embodied carbon productivity of export trade in various sectors of the primary and tertiary industries is relatively high(both greater than 0.1 million yuan/t),while most sectors of the secondary industry are relatively low,especially the high-carbon-intensive industries in the manufacturing industry are the lowest.(2)From 2002 to 2017,the standard deviation,logarithmic deviation and coefficient of variation of carbon productivity embodied in export trade of various sectors showed an increasing trend.There is no“σ”convergence,but there is an absolute“β”convergence and a conditional“β”convergence,indicating that the growth rate of the low-productivity sector is hi
