Water governance, Performance, Index, Model, Spatial and temporal differentiation characteristics.

By designing the regional water governance performance evaluation index system, this paper uses the ideal solution model and the coupling coordination degree model to construct a regional water governance performance evaluation model and takes the Beijing-Tianjin-Hebei region as an example to analyze the spatial and temporal differentiation characteristics of regional water governance performance. Studies have shown that the water resources pressure has been alleviated through optimization of water supply structure, industrial upgrading, agricultural water saving, water-use efficiency improvement and water pollution control, and the water governance performance index in the Beijing-Tianjin-Hebei region has been effectively improved: Beijing, Tianjin, and Hebei has increased from 0.60, 0.52, and 0.49 to 0.98, 0.96, and 0.98, respectively, among which the level of economic governance in the Beijing-Tianjin-Hebei region has been effectively improved, the industrial structure has been continuously optimized, the quality of industrial development has been continuously enhanced, and the water-use efficiency and pollution discharge performance have continued to improve. Beijing's economic governance performance index has the fastest growth rate, with an average annual growth rate of 5.93%; the economic governance performance index growth rate of the Tianjin-Hebei region has reached 2.64%. The economic governance level of the Beijing-Tianjin-Hebei region has been effectively improved, the social water-use structure has been continuously optimized, and the social water demand has been greatly guaranteed. Beijing's social governance performance index has the fastest growth rate, with an average annual growth rate of 5.26%, followed by Tianjin (4.64%) and Hebei (4.34%). The water supply capacity of the Beijing-Tianjin-Hebei region has been greatly guaranteed and the ecological protection has been continuously increased. Beijing's ecological governance performance index has the fastest growth rate, with an average annual growth rate of 4.82%, followed by Tianjin (4.68%) and Hebei (2.78%).
