摘要
为促进中国地区间的协同碳减排,减轻区域贸易活动中的隐含碳排放转移和碳泄漏现象对全国碳减排目标的削弱影响,本研究运用多区域投入产出模型对中国地区间贸易隐含碳排放总量进行测算和可视化分析,并从碳泄漏视角分析了贸易隐含碳流动路径的特征。主要结论:贸易隐含碳的输入输出具有较大的区域差异,净输入区域主要包括华东和西南地区,净输出区域主要集中在华北、东北和西北地区;贸易隐含碳排放主要从第二产业发达或能源资源富集的经济欠发达地区向经济发达地区流动;地区间碳泄漏流通格局与地区间贸易隐含碳相对集中的流通路径基本一致。
In order to promote synergistic carbon emission reduction between regions in China,and mitigate the weakening impact of the implied carbon emission transfer and carbon leakage phenomenon in regional trade activities on national carbon emission reduction targets.This study uses a multi-regional input-output model to measure and visualize the total trade implied carbon emissions between regions in China,and analyses the characteristics of trade implied carbon flow paths from the perspective of carbon leakage.The main conclusions are:There are large regional differences in the input and output of trade implied carbon,with net input regions mainly including East China and Southwest China,and net output regions mainly concentrated in North China,Northeast China and Northwest China;Trade implied carbon emissions mainly flow from economically less developed regions with developed secondary industries or energy resource-rich regions to economically developed regions;The flow pattern of inter-regional carbon leakage is consistent with the relatively concentrated flow path of inter-regional trade implied carbon.The flow pattern of inter-regional carbon leakage is basically consistent with the relatively concentrated flow path of inter-regional trade implied carbon.
