Measurement results of CWRULE.

This research provides an overview of the comprehensive water resources utilization level (CWRULE) in China, highlighting its significance in national water management. The study aims to evaluate performance and trends in CWRULE across various regions. Employing methods such as the Dagum Gini coefficient, spatial kernel density estimation, and spatial convergence models, the analysis explores regional disparities, distribution dynamics, and convergence trends. Key findings indicate that while national water resources management has improved annually, significant disparities persist between the coastal eastern and central regions versus the western and northeastern regions, where CWRULE indicators remain relatively low. Notably, the convergence speed in the central, western, and northeastern regions increases significantly after controlling for variables, showcasing the beneficial impacts of policy support, economic development, and technological advancements. In contrast, the eastern region exhibits weak convergence, underscoring the necessity for targeted strategies to enhance water resources management and efficiency.本研究对中国综合水资源利用水平（Comprehensive Water Resources Utilization Level, CWRULE）的整体发展状况进行了全面综述，并阐明了其在全国水资源管理体系中的重要意义。本研究旨在评估中国各地区综合水资源利用水平的绩效表现与发展趋势。研究采用达古姆基尼系数、空间核密度估计以及空间收敛模型等分析方法，深入探究了区域间的发展差距、分布动态特征与收敛态势。核心研究结果显示：尽管全国水资源管理水平逐年提升，但东部沿海与中部地区同西部、东北地区之间仍存在显著发展差距，后两类地区的综合水资源利用水平指标仍相对偏低。值得注意的是，在控制相关变量后，中部、西部及东北地区的收敛速度显著提升，凸显了政策扶持、经济发展与技术进步所带来的积极推动作用。与之形成鲜明对比的是，东部地区的收敛态势较弱，这进一步凸显了制定针对性策略以提升水资源管理水平与利用效率的必要性。
