Abstract

With the advancement of industrialization, industrial water use efficiency has become a core issue in global water resources management and sustainable development. Evaluation of industrial water use efficiency in China involves multiple dimensions, among which single-index method and multi-index system method are the most commonly used. This paper compared the industrial water use efficiency of Jiangsu and Shandong provinces, adopted the single-index method for calculation and analysis, and assessed the applicability of different single indices in reflecting regional industrial water use efficiency. The results show significant differences in industrial water use efficiency between the two provinces. Jiangsu achieves overall higher industrial water use efficiency with strong stability in both water consumption and water intake per 10⁴ yuan of industrial added value. Shandong, dominated by heavy chemical industries and facing severe water resources constraints, has improved its water use efficiency in recent years through the application of water-saving technologies and industrial structure adjustment. Through comparative analysis and consistency tests, this paper proposed industrial water use efficiency evaluation methods suitable for different regions, providing a scientific basis for the formulation of regional water-saving policies.
