Measurement,Source Decomposition and Formation Mechanism of Eco-civilization Development Gap under the Dual Carbon Goal:Based on the Perspective of Major National Strategies Region
Promoting the eco-civilization development in major national strategic regions in an inte-grated manner is an important means of achieving the goal of carbon peaking and neutrality.On the basis of evaluating the eco-civilization development level of major national strategic regions from 2010 to 2021 using the VHSD-EM model,this paper explores the source of the eco-civilization development gap and its formation mechanism through the Dagum Gini coefficient,the variance decomposition and the QAP meth-od.The results showed that:(1)The eco-civilization development level in the major national strategic regions all showed a fluctuating upward trend,but there were significant inter-and intra-regional gaps,with the highest level of eco-civilization development level in Guangdong-Hong Kong-Macao Greater Bay Area,while that in the Yellow River Basin was at a low level.(2)The main spatial source of the overall gap is the interregional gap,and the main structural source is the green low-carbon transition development gap.(3)QAP regression showed that from the endogenous perspective,the intensity of the role of the green and low-carbon transformation and development gap,the resource conservation,intensification and recycling gap,the spatial pattern optimisation gap,the ecological environmental protection and restoration gap,and the institutional soundness and guarantee gap in the regional eco-civilization development gap has decreased by an order of magnitude.From the exogenous perspective,the digital divide,the opening-up gap and the marketization gap were the main reasons for influencing the formation of the regional eco-civilization development gap.This research can provide a reference for comprehensive and synergistic en-hancement of regional eco-civilization development.
