Against the backdrop of rapid industrialization and water scarcity, and in response to the United Nations call for sustainable development, this paper utilizes industrial sustainable water use indicator data from 30 provinces in China. Using a two-stage parallel two-stage SBM dynamic (PTSD) model, the paper calculates interprovincial industrial sustainable water use efficiency and employs a gravity shift model for evaluation, aiming to provide policy recommendations for achieving sustainable development in industrial water use. The analysis reveals (1) disparities in interprovincial sustainable water use efficiency in China, with higher efficiency observed in the eastern provinces and lower efficiency in the western provinces. (2) The environmental governance stage in the two-stage model exerts a greater influence on overall efficiency than the production stage. (3) The gravity shift shows an initial southward movement followed by a shift towards the northeast, with the overall efficiency being higher in the eastern regions compared to the central and western regions. This study not only fills the gap in the academic research on industrial water use efficiency from a sustainable development perspective but also aligns with the United Nations call for sustainable development, reflecting the policy requirements of pursuing sustainable development in our country. It contributes to improving residents living environment, promoting industrial upgrading, and facilitating balanced regional development.
