摘要
区域间的隐含碳排放流动与碳排放的转移密切相关,甚至可能造成碳泄漏,影响国家“双碳”目标的实现。利用我国多区域投入产出数据,从价值链视角揭示了区域隐含碳排放流动的路径、方向及来源。研究发现,在研究期间,各区域流出隐含碳排放总量呈现先增长后下降的趋势,且地域上呈现“西高东低,北高南低”的格局;区域流出隐含碳排放的部门贡献有明显的区域异质性,京津及沿海地区集中于服务业和轻工业,中西部地区贡献最大的是资源行业。该结果对制定区域差异化碳减排政策具有一定政策启示。
The flow of embodied carbon emissions between regions is closely related to the transfer of carbon emissions,and may even cause carbon leakage,which affects the realization of national carbon emission reduction targets.Using China′s multi-regional input-output data,it reveals the path,direction and source of regional embodied carbon emissions from the perspective of the value chain.The study found that:During the study period(2007-2017),the total outflow embodied carbon emissions in each region showed a trend of first increasing and then decreasing,and the pattern showed a pattern of“high in the west and low in the east,high in the north and low in the south”in the region.The sectoral contribution of the embodied carbon emissions from regional outflows has obvious regional heterogeneity.Beijing-Tianjin and coastal areas concentrate on service industries and light industries,and the central and western regions have contributed the most to the resource industries.This result has certain policy implications for formulating regionally differentiated carbon emission reduction policies.
