Research on Coordination Evaluation of Water Resources Utilization and Economic Development in Beijing

The coordination degree evaluation method is used to evaluate the coordination degree of industrial water utilization structure and industrial structure in Beijing. On this basis, it is suggested to design the evaluation index system for the coordination of water resources utilization and economic development in Beijing, and the grey correlation analysis method and coordination degree evaluation method are used to evaluate the correlation degree and coordination degree between the utilization of water resources and economic development in Beijing. According to the research, it is found that during the period from the "Eighth Five-Year Plan" to "Thirteenth Five-Year Plan", the extensive degree of industrial water utilization structure in Beijing has shown a significant decline, from 0.71 to 0.36; the partiality to high water consumption in Beijing has a slight fluctuation and decline, from 0.29 to 0.09; and the coordination degree between industrial water utilization structure and the industrial structure in China has increased from 0.54 to 0.82, changing from a "comparatively coordinated" state to a "coordinated" state. The grey correlation degree between water resources utilization and economic development in Beijing has shown a slightly upward trend, from 0.59 to 0.89. The coordination degree between water resources utilization and economic development in Beijing has a small fluctuation range, increasing from 0.83 to 0.87.
