区域间贸易对上海市能源碳排放影响

IMPACT OF INTER-REGIONAL TRADE ON SHANGHAI’S ENERGY-RELATED CARBON EMISSIONS

构建了1个基于贸易活动的区域间能源碳排放集群模型,用于评估区域间贸易对上海市碳排放的影响。结果表明:上海市是一个碳排放净进口城市,其省外中间使用所产生的碳排放影响大于省外中间投入和最终消费带来的碳排放影响。在上海市的省外中间使用产生的碳排放中,浙江、广东和江苏是贡献最多的省份。而在整体省外中间投入方面,山东、黑龙江、天津和内蒙古是最关键的省份。从行业角度来看,金属冶炼和轧制加工业部门,电力和热力的生产和供应部门分别是省外中间使用和省外中间投入中较为重要的行业。

The article developed an inter-regional energy carbon emission cluster model(IRCE) based on trade activities to assess the impact of inter-regional trade on carbon emissions in Shanghai.It was found that Shanghai was an externally oriented city,and the impact of carbon emissions from out-of-province intermediate use was greater than the impact of carbon emissions from out-of-province intermediate inputs and final consumption.Zhejiang Province,Guangdong Province and Jiangsu Province were the provinces with the highest carbon emissions from out-of-province intermediate use in Shanghai.Shandong Province,Heilongjiang Province,Tianjin City and Inner Mongolia Autonomous Region were the most critical provinces for overall out-of-province intermediate inputs.From a sectoral perspective,the metal smelting and rolling processing sector,and the production and supply of electricity and heat sector were the more important sectors in out-of-province intermediate use and out-of-province intermediate input,respectively.
