我国各地区碳减排责任再考察——基于省际碳排放转移测算结果

The Review on Regional Responsibility for Carbon Reduction in China——Based on the Transfer of Inter-provincial Carbon Emissions

笔者基于我国30个省区扩展型投入产出表,对省际产品贸易之隐含碳排放进行测算,以有效反映各省区碳排放强度,为合理制定地区减排目标提供参考。笔者研究认为:从国内贸易看,存在高碳排放产品由能源富集区流向东部沿海地区的空间特征;从国际贸易看,碳排放进出口主要集中在沿海地区。国家分配减排责任时,应强化"消费者负责"原则,适度增加高能耗产品消费地减排责任,激励沿海省份对能源富集省份进行资金、技术和人才支持,以实现全国总体减排目标。

Based on extended input - output tables of 30 provinces, we estimated the embodied carbon emissions in inter-provincial trade. It is found that ： （ 1 ） in the domestic trade, carbon emissions transferred from energy rich regions to east coastal regions ; （2） for international trade, the import and export of carbon emissions is mainly concentrated in coastal regions. Based on the principle of ＂con- sumer responsibility＂, when distributing the regional responsibility for emissions reductions, China should appropriately increase the re- sponsibility on consumer of energy - intensive products, while cut the responsibility on producer relatively. For achieving the overall national emission reduction targets, it is very important to incentive eastern coastal provinces to support the energy rich provinces with financial, technical and personnel means.
