摘　　要：以长江经济带为分析对象,从多元耦合协调度与空间视角出发,利用耦合协调度模型对2008—2019年该区域内11个省市的碳排放-经济-环境三系统的耦合协调度进行探究,并使用莫兰指数对耦合协调度进行空间相关性分析。研究结果表明:长江经济带各子系统均呈现波动增长的趋势并趋于平衡,整体耦合协调度类型由中度耦合协调转变为高度耦合协调;从各省市层面来看,耦合协调度呈现出“东高西低、下游>中游>上游”的阶梯状地域分布特征;长江经济带耦合协调度存在显著的空间集聚性,主要表现为下游江浙沪的高-高聚集与上游的低-低聚集。为促进该区域的高水平协调发展,未来可以从优化产业结构、促进深度合作等方面进行突破。Taking the Yangtze River Economic Belt as the analysis object,an inquiry has been made into the coupling coordination degree of carbon emissions,economy,and environment in 11 provinces and cities in the region from 2008 to 2019 by using a coupling coordination degree model from the perspective of multiple coupling coordination degrees and space,followed by an analysis of the spatial correlation of the coupling coordination degree by using Moran index.The results show that all subsystems of the Yangtze River Economic Belt show a trend of fluctuating growth leading to a balance,with an overall coupling coordination degree type changing from a moderate coupling coordination to a high coupling coordination degree.From the level of various provinces and cities,the coupling coordination degree is characterized with a feature of“high in the east and low in the west,from downstream throuh middle stream to upstream”.The coupling coordination degree of the Yangtze River Economic Belt exhibits a significant spatial agglomeration,mainly manifested as a high-high aggregation in the downstream of Jiangsu,Zhejiang and Shanghai as well as a low-low aggregation in the upstream.In order to enhance the high-level coordinated development of the region,breakthroughs can be made so as to realize an optimization of the industrial structure and a promotion of the in-depth cooperation in the future.
