长江流域数字经济、碳排放与高质量发展耦合协调水平研究

Spatial-temporal Coupling and Driving Factors of Digital Economy,Carbon Emission And High-quality Development in the Yangtze River Basin

文章以长江流域18个省市为研究对象,在梳理数字经济-碳排放-高质量发展系统(以下简称DCH系统)耦合协调机理的基础上,构建评价指标体系,利用耦合协调度、空间自相关模型,测算2011—2021年长江流域DCH系统耦合协调水平。研究表明:长江流域DCH系统耦合协调水平呈上升趋势,整体上呈现“东南高、西北低”的空间分布和“东南向西北扩散”的演变格局;长江流域DCH系统耦合协调度在省市层面表现出显著空间正相关性,但集聚趋势不明显且程度不高。基于此,文章从顶层设计、分类施治和区域合作角度提出发展建议,旨在为促进长江流域生态、经济协同高质量发展建言献策。

Taking 18provinces and cities in the Yangtze River Basin as the research objects,this paper constructs an evaluation index system based on the analysis of the coupling and coordination mechanism of the digital economy-carbon emissions-high-quality development system(hereinafter referred to as the DCH system).By using the coupling coordination degree and spatial auto correlation model,the coupling coordination leve lof the DCH system in the Yangtze River Basin from 2011to 2021is measured.The research shows that:(1)The coupling and coordination level of the DCH system in the Yangtze River Basin is on the rise,presenting a spatial distribution pattern of“high in the southeast and low in the northwest”and an evolution pattern of“diffusion from southeast to northwest”.(2)The coupling and coordination degree of the DCH system in the Yangtze River Basin shows significant spatial positive correlation at the provincial and municipal level,but the clustering trend is not obvious and the degree is not high.Based on this,development suggestions are proposed from the perspectives of top-level design,classified treatment,and regional cooperation,aiming to provide advice and suggestions for promoting the coordinated and high-quality development of the ecology and economy in the Yangtze River Basin.
