Results showed that manufacturing carbon emissions of Jilin Province increased 1.304 ~ 107t by 66% between 2004 and 2010. However, 2012 was a remarkable year in which carbon emissions decreased compared with 2011, the first fall since 2004. Industrial activity was the most important factor for the increase of carbon emissions, while energy intensity had the greatest impact on inhibiting carbon emission growth. Despite the impact of industrial structure on carbon emissions fluctuated, its overall trend inhibited carbon emission growth. Further, influences of industrial structure became gradually stronger and surpassed energy intensity in the period 2009-2010. These results conclude that reducing energy intensity is still the main way for carbon emission reduction in Jilin Province, hut industrial structure can not be ignored and it has great potential. Based on the analyses, the way of manufacturing industrial structure adjustment for Jilin Province is put forward.展开更多
物流业是能源消耗和碳排放的主要产业,碳达峰、碳中和目标的提出将对物流业发展产生深远的影响,因此行业低碳化发展成为亟须解决的问题。运用碳排放系数法测度福建省2012—2021年物流业碳排放总规模,在此基础上利用对数平均迪式指数分解...物流业是能源消耗和碳排放的主要产业,碳达峰、碳中和目标的提出将对物流业发展产生深远的影响,因此行业低碳化发展成为亟须解决的问题。运用碳排放系数法测度福建省2012—2021年物流业碳排放总规模,在此基础上利用对数平均迪式指数分解法(logarithmic mean Divisia index,LMDI)模型分析能源结构、能源效率、产业结构、经济增长和人口因素对福建省物流业运行效率的影响。研究结果显示:经济增长、能源效率和人口因素对福建省物流业碳排放总量增加起促进作用,其中经济增长因素的促进作用最大;能源结构和产业结构因素对福建省物流业碳排放增加起抑制作用。最后,基于实证分析结果,提出推动福建省物流业低碳化发展建议。展开更多
