Research On Carbon Emission Reduction Mechanism Of Resource-based Industry From Spatial Perspective

Resource-based industries,as the basis of industrial development,have an important significance for industrial emission reduction through reasonable carbon reduction.And resource-based industries are closely connected with each other,forming a complex industrial system.This paper studies the carbon emission reduction mechanism of resource-based industries based on spatial perspective,firstly,the spatial characteristics of direct carbon emission and implied carbon emission are studied by spatial effect test and complex network analysis respectively,then the spatial differences and correlations are analyzed by spatial spillover effects,followed by the identification of key regional sectoral paths of carbon emission by structural path analysis,and the application of IOSDA and QAP methods to reveal the industry-linked The spatial spillover effects,carbon emission key paths and carbon emission drivers are then used as references for the analysis of carbon emission reduction mechanisms in resource-based industries.The main findings of this paper are as follows.(1)The large variability of direct carbon emissions from various sectors of resourcebased industries in China indicates that the structure of China’s crude resource-based industries has not yet been changed,the carbon emissions from resource-based industries are spatially correlated,and the spatial local dependence and variability of carbon emissions from 30 Chinese provinces exist simultaneously.During the period of 2002-2015,the main leaps are HH→HH,HL→HL,LH→LH and LL→LL(HH: high carbon emission intensity-high spatial lag,HL: high carbon emission intensity-low spatial lag,LH: low carbon emission intensity-high spatial lag,LL: low carbon emission intensitylow spatial lag),centered on Hebei province,and the surrounding provinces form a high carbon emission levels.The network density of the implied carbon emission flow network among regional sectors of resource-based industries in China is high and the industries are closely related,so when formulating carbon emission reduction policies,the first step should be to start from the central regional sector and take advantage of the tightness of the network to give full play to the synergistic effect of carbon emission reduction policies.(2)From the perspective of the spatial spillover effect of carbon emissions of resource-based industries,the carbon emissions of resource-based industries in the more developed regions show a high degree of intra-provincial flow,and the degree of external linkage is not high,and the overall characteristics of "internal export-dependent",central provinces such as Henan play the function of bearing the east and enlightening the west,and Hebei represents The resource-based industries in the northern coastal areas account for a relatively high proportion,and the regional carbon emissions of resource-based industries are growing under the circumstance of rough development.The Beijing-Tianjin region has less resource-based industrial layout and mainly relies on imports.The resource-based industry structure in the southwest region is also lagging behind,and it is more difficult for the resource-based industries to vigorously pull up carbon emissions.In the northern,eastern coastal and central regions,the interactive spillover effects of resource-based industries are generally obvious in regions close to each other or between two regions,while the spillover effects in regions farther apart are generally not significant,which reflects the distance-decaying characteristics of the carbon emission spillover effects of resource-based industries in the region.(3)In terms of the overall structure of the path tree,intersectoral interactions begin to extend throughout the spatial economic system in the second stage.In addition to carbon emissions generated directly in the production process of resource-based industries,from non-metallic mineral products(S13)and metal smelting and rolling processing industries(S14)to the provincial construction industry are the most important carbon emission pathways for each province.The regional analysis shows that Hebei and Inner Mongolia are the main regions in northern China to take up carbon emissions from resource-based industries,and Henan is identified as the carbon emission import hub for resource-based industries in the east and west.The sectoral analysis yields non-metallic mineral products(S13),metal smelting and pressing(S14),and petroleum,coking products and processed nuclear fuel products(S11)are identified as the major carbon emission exporting industries in the first phase.General equipment(S16)and transportation equipment(S18)also have a significant indirect impact on the carbon emissions of resource-based industries.(4)The SDA results show that for the secondary sector of resource-based industries,the impact of drivers of carbon emission inflow intensity varies significantly across periods or sectors.The contribution of direct energy consumption intensity is higher in2002-2007,but decreases in the latter period,2007-2012.The contribution of energy structure effect changes in the opposite direction,with a low contribution to emission reduction in the former period and a significant climb in the latter period.The QAP regression analysis shows that the reduction of employment numbers and environmental regulation differences can significantly contribute to the spatial association of carbon emissions in resource industries.Therefore,reasonable development programs should be proposed for resource industries to continuously reduce the differences in human resources and environmental regulations in resource industries across provinces.Based on the above conclusions,this paper presents a specific analysis of carbon emission reduction mechanism from three aspects: spatial spillover effects,key paths and driving factors,and proposes corresponding policy recommendations.The innovations of this paper are as follows: first,a systematic study of carbon emissions from resource-based industries by combining spatial theory and input-output analysis of environmental expansion;second,an intuitive and in-depth analysis of the spatial interactions of carbon emissions from resource-based industries through inputoutput analysis and complex networks from two perspectives of spatial association and industrial association;third,a comprehensive and systematic analysis of carbon emission impact mechanisms of resource-based industries in China from three aspects: spatial spillover effects,critical paths and driving factors.
