摘要
从耦合和空间演化的角度,测度了30个省份碳排放—经济增长—生态环境三维系统的耦合协调度,并分析了各省份耦合协调度的空间相关性。研究结果发现:我国各省份三维系统基本处于轻度失调和勉强协调的状态,地理分布的空间异质性特征明显,空间相关性的研究表明,三维系统存在逐年降低的正相关关系。部分省份表现出空间聚集的特征,河南、山西等省份存在“高—高”聚集效应,新疆存在“低—低”聚集效应,大多数省份不存在空间聚集效应。根据实证分析结果,从调整能源结构、推动区域低碳减排合作等方面提出了相关政策建议。
From the perspective of coupling and spatial evolution,the degree of coupling and coordination of the threedimensional system of carbon emissions,economic growth,and ecological environment in 30 provinces is measured.The spatial correlation of the degree of coupling and coordination of each province is analyzed.The results of the study found that the three-dimensional systems of the country’s provinces are basically in a state of slight imbalance and barely coordinated,and the spatial heterogeneity of geographical distribution is obvious;the research of spatial correlation shows that the three-dimensional system has a positive correlation that decreases year by year.Some provinces show the characteristics of spatial agglomeration.Provinces such as Henan and Shanxi have a “high-high” agglomeration effect,Xinjiang has a “low-low” agglomeration effect,and most provinces do not have a spatial agglomeration effect.Based on the results of the empirical analysis,relevant policy recommendations were put forward in terms of adjusting the energy structure and promoting regional cooperation in low-carbon emission reduction.
