| In recent years,severe climate and environmental problems caused by increased carbon emissions have led countries around the world to reach consensus on carbon reduction.China,as a responsible big country,has made its commitment to reduce emissions to the world.Achieving the emission reductions goal promised to the international community on schedule is the most important manifestation of China’s active participation in global climate governance and practicing the “Paris Agreement”.The Chinese government has actively adopted a “top-down” carbon emission management strategy to decompose the overall national emission reduction targets to provinces and industrial sectors gradually which is an important measure to strengthen carbon emission control,build ecological civilization and promote green development for China.As the main body of carbon emission activities,the industrial sector is an important control object for energy conservation and emission reduction,and plays a vital role in the smooth implementation of national emission reduction targets.Therefore,the study focuses on the analysis of carbon emissions responsibilities in the industrial sectors.First of all,determine 18 industrial sectors as the focus of the study including agriculture,forestry,animal husbandry and fishery products and services and coal mining products.On this basis,the study accounts the overall carbon emissionresponsibility of industrial sectors and the distribution of inter-provincial carbon emissions of various sectors in 30 provinces in China separately based on “production-based responsibility”,“consumption-based responsibility” and “income-based responsibility” by the multi-region input-output analysis method,using the inter-regional input-output table of2012 as the main data base.Finally,an in-depth analysis of the accounting results is conducted to explore the main reasons for the formation of carbon emission differences.The study found that various industrial sectors have different carbon emission characteristics from different perspectives of responsibility.In terms of overall carbon emissions of industrial sectors,horizontal comparison shows that 11 of the 18 industrial sectors have the highest carbon emissions observations from the perspective of “production-based responsibility”,mainly in the agricultural and industrial sectors.5 sectors have the highest carbon emissions observations from the perspective of“consumption-based responsibility”,mainly in the relevant sectors of industry and services.2 sectors have the highest carbon emissions observations from the perspective of “income-based responsibility” and all are factor supply sectors.Vertical comparison shows that under the three responsibility perspectives,“metal resources”,“power and heat production and supply”,“mechanical industry”,“construction industry” and other departments have assumed higher carbon emission responsibility,and thesedepartments should be the key target of carbon emission reduction work.In terms of the inter-provincial distribution of carbon emissions responsibility of industrial sectors,the carbon emission responsibility of the “electricity and heat production and supply” department is mainly distributed in Shanxi,Hebei and Inner Mongolia.The carbon emission responsibility of the “Metal Resources” sector is mainly distributed in Hebei,Shandong and Henan.The carbon emission responsibility of “financial industry” sector is mainly distributed in Beijing,Shanghai,Shandong,Guangdong,Jiangsu and Zhejiang.Based on this,the study puts forward suggestions on the formulation of national-level emission reduction programs,the implementation of provincial-level emission reduction policies,and the optimization and upgrading of industrial structure,in order to provide a certain reference for the smooth realization of national emission reduction targets. |
