Research on Regional Embodied Carbon Emissions and the Industrial Correlation under the Background of Dual-carbon Goal—A Case Study of the Power Industry in Guizhou Province
To contribute to the realization of the national dual-carbon goal,carbon emission reduction in the power sector,the key emission sector,is crucial.This paper first constructed the embodied carbon emission transfer matrix of inter-provincial trade in Guizhou province based on the multi-regional input-output model.Then structural decomposition analysis was used to identify the driving factors of embodied carbon emission changes.Then the input-output model of Guizhou Province was used to solve the industrial linkage coefficients and analyze the carbon emissions of the industrial chain as well as the industrial linkages.The results show that there is spatial heterogeneity in the pattern of embodied carbon emission transfer in Guizhou province,and the net embodied carbon transfer there was 58 and 23.5 MT from 2012 to 2017,which belongs to the embodied carbon transfer provinces.Embodied carbon emissions from the power sector in Guizhou province increased by 3.5MT over five years,mainly due to changes in final demand and carbon intensity.Secondly,other industries have a higher degree of dependence on the power industry,which makes the power industry bear most of the embodied carbon emissions of the remaining industries.Furthermore,the influence coefficient and inductance coefficient of the electric power industry in Guizhou province are both greater than 1,indicating that it has a greater role in promoting the development of other industries.The conclusions of this study can provide certain references for the formulation of regional carbon emission reduction policies under the dual-carbon background as well as the optimization and management of the power industry chain in Guizhou province.
