中国国际贸易中的碳足迹核算

The Carbon Footprint Accounting of China's International Trade

使用投入产出模型核算中国进出口贸易中的碳足迹,模型中改进了进口碳强度的估算方法,分解了进口品用作中间投入和最终使用的量。结果表明,我国是碳足迹净出口国,且出口碳足迹的增速高于进口碳足迹的增速;不同核算原则下我国负责的碳足迹量差异较大,消费负责的核算原则对我国更有利;碳足迹逆差的部门主要集中在电气电子设备制造业、纺织和纺织制品业、化学工业、金属制品业等行业,这些部门应成为我国国际贸易的重点调控部门。

This study uses a modified Input-Output model, in which the import carbon intensity is reevaluated and the import goods are divided into two parts, and several results are achieved. First, China is net-exporter of Carbon Footprint and Export Carbon Footprint is increasing much faster than Import Carbon Footprint. Second, there is a large gap from the results between the two different ac- counting principles and China is more benefited from the Consumption-Based Principle. Third, the Carbon Footprint trade deficit of China is mainly from Electrical Manufacture, Textile, Chemical In- dustry and Metal Products. These sectors are supposed to be regulated by a large extent.
