| 合理界定碳排放责任,开展省域间碳补偿是促进区域协同减排的重要途径.基于2017年多区域投入产出表,使用增加值贸易分解方法对各省市碳排放进行了分解,测算了省域间的隐含碳流动,并设计了基于减排成本的差异化碳补偿机制,为我国开展横向碳补偿提供了参考.结果表明:①省内最终需求引致碳排放占比53.56%、省外最终需求引致碳排放占比32.49%,省域间隐含碳流动显著存在; ②隐含碳总体呈现出从北部、中部地区向京津地区和东南沿海地区转移的显著流动特征; ③生产者、消费者和责任共担视角下各省市的碳排放总量相等,其中责任共担的分配思路体现了"受益原则".④省域间碳减排成本存在差异,碳减排成本低的地区直接碳排放量高,产业以重工业为主,碳减排成本高的地区直接碳排放量低,产业以高新技术产业和服务业为主.⑤基于减碳成本各省市需支付(接受)的补偿金额不等,其中,广东需支付的补偿金额最高,内蒙古的受偿金额最高. |

| A reasonable definition of carbon emission responsibility and inter-provincial carbon compensation is an important approach to promote regional coordinated emission reduction. Here, based on the 2017 multi-regional input-output table, carbon emissions from provinces were decomposed by using the value-added trade decomposition method, the embodied carbon flows between provinces were measured, and a differentiated carbon compensation mechanism based on emission reduction cost was designed, which provides the reference for China to carry out horizontal carbon compensation. The main conclusions were as follows:①the carbon emissions caused by the final demand within the province accounted for 53.56%, whereas the carbon emissions caused by the final demand outside the province accounted for 32.49%. The embodied carbon flows among provinces showed a significant existence. ②The embodied carbon showed a significant flow characteristic of transferring from the northern and central regions to the Beijing-Tianjin region and the southeastern coastal regions. ③From the perspective of producers, consumers, and shared responsibility, the total carbon emissions of provinces and cities were equal, and the distribution idea of shared responsibility reflected the "benefit principle." ④There were differences in carbon emission reduction costs between provinces. In areas with low carbon emission reduction costs, direct carbon emissions were high, and the industries were dominated by heavy industry. In areas with high carbon emission reduction costs, direct carbon emissions were low, and the industries were high-tech industries and service industries. ⑤The amount of compensation to be paid/accepted by provinces varied based on the cost of emission reduction. Among them, Guangdong had the highest amount of compensation to be paid, and Inner Mongolia had the highest amount of compensation to be accepted. |
