| 研究目标：揭示黄河流域生态效率的空间差异、动态演进及驱动因素。研究方法：构建MinDS模型测算2004~2017年黄河流域生态效率水平，采用Dagum基尼系数和核密度估计方法探究其空间差异和动态演进，借助地理探测器考察生态效率时空演进的驱动因素。研究发现：黄河流域生态效率呈现“东高西低”空间分布格局；区域间差异是生态效率空间差异的主要来源；中上游地区内部生态效率的绝对差异呈扩大态势，流域整体及三大地区均存在右拖尾和极化现象；从内源性因素看，经济发展差异是生态效率空间差异的主导因素，经济发展与能源消耗的交互组合是关键性驱动因素；从外源性因素看，人口密度差异对流域整体及中上游地区的驱动作用较高，外在因素协同作用增强了对生态效率时空演进的解释力。研究创新：基于城市视角考察黄河流域生态效率的时空演进规律，并从内源和外源两个层面揭示其成因。研究价值：为推动黄河流域生态效率协同提升提供有益借鉴。 |

| Research Objectives: Reveal the spatial disparity, dynamic evolution and driving factors of ecological efficiency in the Yellow River Basin. Research Methods: This paper uses MinDS model to measure the ecological efficiency in the Yellow River Basin from 2004 to 2017. Dagum gini coefficient and kernel density estimation method are used to investigate the spatial disparity and dynamic evolution of urban ecological efficiency in the Yellow River basin, and the geographic detector is further used to analyze driving factors of the spatiotemporal evolution of eco-efficiency. Research Findings: The spatial distribution pattern of ecological efficiency in the Yellow River Basin is “high in the east and low in the west”. Intra-regional differences are the main source of spatial differences in ecological efficiency in the Yellow River Basin. The absolute difference in eco-efficiency in the middle and upper reaches of the Yellow River basin tends to expand. There are right-trailing and polarization phenomena whether in the whole basin or in three regions. From the perspective of endogenous factors, the economic development disparity is the leading factors for the spatial differences of eco-efficiency, and the comprehensive effect of economic development and energy consumption is the most important interactive driving factor. From the perspective of exogenous factors, the determinant of population density disparity is the highest for the whole basin, upper and middle reaches. The synergistic effects of exogenous factors enhance the explanatory power of the spatiotemporal evolution of ecological efficiency. Research Innovations: Based on the urban perspective, this paper examines the temporal and spatial evolution of ecological efficiency in the Yellow River Basin, and reveals its causes from the endogenous and exogenous factors. Research Value: Provide a useful reference for coordinately improving the ecological efficiency in the Yellow River Basin. |
