摘要
基于2010～2022年中国内地30个省(区、市)(不包含西藏)数据,采用耦合协调度模型、基尼系数分解和空间杜宾模型等方法,分析绿色金融与碳排放效率耦合协调的时空格局及影响因素.研究发现:我国"绿色金融-碳排放效率"系统呈现"高耦合度、低协调度、低发展水平"的整体特征;两系统耦合协调度表现出稳步上升的趋势及"东高西低"的梯度式空间分布格局,同时伴随着空间集聚现象和区域不平衡性,耦合协调度的总体差异主要来自区域间差异,且呈现出扩大的趋势;政府干预以及金融化程度正向促进系统间的耦合协调发展且政府干预在空间上具有正外部性,而产业结构则有显著抑制作用和负外部性,城镇化水平的负外部性特征明显.因此,可以通过政银联动、政企合力和强化区域空间关联等方式提升绿色金融与碳排放效率的耦合协调水平,缩小区域间差异.
Abstract
Based on the data of 30 provinces(municipalities)in mainland China(excluding Tibet)from 2010 to 2022,the spatial and temporal patterns and influencing factors of the coupling and coordination of green finance and carbon emission efficiency are analyzed by using the coupling coordination degree model,Gini coefficient decomposition,and spatial Durbin model.It is found that China's green finance-carbon emission efficiency system presents the overall characteristics of a high coupling degree,low coordination degree,and low development level;the coupling and coordination degree of the two systems show a steadily rising trend,and a gradient pattern of high in the east and low in the west.The degree of coupling coordination between the two systems shows a steadily increasing trend and a gradient spatial distribution pattern of east high and west low,accompanied by the phenomenon of spatial aggregation and regional imbalance,and the overall difference in the degree of coupling coordination mainly comes from the inter-regional differences and shows a tendency to expand;the degree of government intervention and financialization positively promotes the coupling coordination of the development of the inter-systems,and the government intervention in space has a positive externality.In contrast,the industrial structure has a significant inhibitory effect and negative externality.And negative externality,the negative externality of urbanization level is obvious.Therefore,the level of coupling and coordination between green finance and carbon efficiency can be increased and inter-regional disparities reduced through government-bank linkages,government-business synergies and strengthening regional spatial linkages.
