Analysis of the Relevance Between Water Resources Utilization and Industrial Development in Beijing

The authors analyze the evolution of Beijing's water resources utilization based on changes in Beijing's industrial water use, adjustment of water structure and changes in water efficiency. At the same time, combined with changes in Beijing's economic and industrial development, the authors use the method of industrial structure change coefficient to reveal the direction of Beijing's industrial structure change. On this basis, the grey correlation evaluation method is used to measure the correlation between water resources utilization and industrial structure in Beijing. And the Tapio elasticity coefficient method is used to determine the water elasticity coefficient for the three industries in Beijing. Studies have shown that during the "Eighth Five-Year Plan" to "Thirteenth Five-Year Plan" period, Beijing's industrial and agricultural water consumption has fallen rapidly, and domestic water consumption has risen rapidly, changing from the largest proportion of agricultural water to the largest proportion of domestic water. The average value of the change coefficient of the primary and secondary industry structure in Beijing is always negative, and the average value of the change coefficient of the tertiary industry structure is always positive. The tertiary industry is showing a relatively stable expansion trend. Beijing's primary industry has the highest correlation with water resources utilization, followed by the secondary industry, and the tertiary industry is the lowest. The correlation between the three industries in Beijing and the utilization of water resources has shown a gradual decline. The water elasticity coefficients of the primary and secondary industries are generally negative, and the water elasticity coefficients of the tertiary industry are always positive.
