安徽省工业水资源效率与经济发展水平耦合协调性分析

Analysis of Coupling Coordination Between Industrial Water Resources Efficiency and Economic Development Level in Anhui Province

采用Super-SBM模型测算2012—2021年安徽16市工业水资源效率,从经济规模、经济潜力、经济活力三个维度构建经济发展水平评价指标体系,利用熵权-综合指数法计算其经济发展水平,引入耦合协调度模型探究工业水资源效率与经济发展水平间的关系,并使用Dagum基尼系数分析其空间差异来源。结果表明:2012—2021年,安徽工业水资源效率呈上升趋势,一直处于无效状态,合肥一直处于超效状态,淮南不升反降;安徽工业水资源效率与经济发展水平耦合协调度由中度失调衰退型晋级到濒临失调衰退型,各城市耦合协调度均有上升,区域间发展不平衡;安徽耦合协调度总体基尼系数呈现下降趋势,皖中在地区内差异中占主导地位,地区内空间差异贡献最大。

The coordinated development of industrial water resources efficiency and economic development level is an important guarantee for the high-quality development of Anhui.The Super-SBM model was used to estimate the industrial water resources efficiency of 16 cities in Anhui Province from 2012 to 2021.The economic development level evaluation index system was constructed from three dimensions:economic scale,economic potential and economic vitality,and the economic development level was calculated by entropy weight-comprehensive index method.The coupling coordination degree model was introduced to explore the relationship between industrial water resources efficiency and economic development level,and the Dagum Gini coefficient was used to analyze the sources of spatial differences.The results showed that:From 2012 to 2021,the industrial water resource efficiency in Anhui was on the rise and remained in a state of ineffectiveness,Hefei was in a state of supereffect,and Huainan was on the decline instead of rising.The coupling coordination degree between industrial water resources efficiency and economic development level of Anhui province has been promoted from the moderate imbalance decline type to the verge of imbalance decline type,and the coupling coordination degree of each city has increased,and the inter-regional development is unbalanced.The overall Gini coefficient of Anhui coupling coordination degree showed a downward trend,and central Anhui dominated the intra-regional differences,and the intra-regional spatial differences contributed the most.
