摘 要:文章采用熵权法和SBM-DEA测算了2006—2021年长江中游城市群28个地级及以上城市的绿色金融水平与绿色创新效率,并运用耦合协调、空间自相关和空间滞后的Tobit模型对绿色金融与绿色创新效率的时空耦合协调状况及其驱动因子进行识别分析。研究发现:(1)时间序列上,长江中游城市群绿色金融和绿色创新效率耦合协调关系虽有波动但整体仍呈稳定上升趋势,近年来出现了上升状态疲软的趋势。(2)空间特征上,长江中游城市群绿色金融和绿色创新效率耦合协调水平由低到高、由混乱到稳定,区域差异表现为环长株潭城市群>环鄱阳湖城市群>武汉都市圈。(3)驱动因素上,正向驱动因子的影响强度表现为人力资本>地区科技支出>政府干预>经济基础,负向驱动因子为产业结构。研究提出,要筑牢绿色金融与绿色创新效率耦合增长的动力系统、联动各地区核心区域带动周边区域和建立绿色产业联盟等对策建议。This paper uses the entropy weight method and SBM-DEA to measure the green finance level and the green innovation efficiency of the urban agglomerations in the middle reaches of the Yangtze River from 2006 to 2021,respectively.It assesses the spatio-temporal coupling coordination status between the green finance and the green innovation efficiency,and analyzes its driving factors by the means of the coupling coordination model,the spatial autocorrelation model and the spatial lag Tobit model.It is found that:1) The coupling coordinated relationship between the green finance and the green innovation efficiency fluctuates but still shows an upward trend in urban agglomerations of the middle reaches of the Yangtze River,and there is a tendency for the upward state to weaken.2) The coupling coordination level between the green finance and the green innovation efficiency ranges from low level to high level,from chaotic state to stable state in urban agglomerations of the middle reaches of the Yangtze River.It has the biggest the regional difference in Changsha-Zhuzhou-Xiangtan urban agglomeration,followed by Poyang Lake urban agglomeration,and Wuhan Metropolitan Area.3) The influence intensity of positive driving factors from high to low is human capital,regional science and technology expenditure,government intervention,economic foundation,respectively.The negative driving factor is industrial structure.It puts forward some development suggestions:building the power system of coupled growth of green finance and green innovation efficiency,linking the core regions of each region to drive the neighboring regions,and establishing green industry alliance.
