Comprehensively improving the efficiency of water resource utilization is not only an urgent need to resolve the prominent contradiction between water supply and water demand but also an inevitable requirement to promote the harmonious coexistence between humans and nature. The compulsory water resource tax is considered to be a powerful tool for resolving the worldwide water crisis and improving water resource utilization efficiency (WRUE). Based on a quasi-natural experiment of water resource tax policy in China, this study used panel data for 30 provinces (municipalities) from 2011 to 2019 to evaluate the impact of water resource tax policies on WRUE through a multistage difference-in-difference model. The results showed that the water resource policy can effectively improve the utilization efficiency of water resources by optimizing the allocation of resources. In addition, the analysis of the spatial heterogeneity showed that the policy of the water resource tax has a stronger lifting effect on improving water resource-use efficiency in eastern China than that in the central and western regions. This research provided insights into China's water policies that can be used to better manage natural resources.

Levying a water resources tax policy which is called ‘fee to tax’ is a regulation formulated by China to restrain and alleviate water poverty. To test the effect of the water resources ‘fee to tax’, this research employs a multistage dynamic difference-in-differences (DID) model to explore whether the implementation of the policy can help alleviate water poverty based on panel data from 2009 to 2019. The results indicate the water poverty in western China is significantly more serious than in other regions and the implementation of the water resources tax policy significantly alleviates water poverty (the sign of the policy is positive and significant at the 1% level) in China. Additionally, the mechanism effects suggest that the policy can effectively restrain water poverty by reducing groundwater exploitation and optimizing the water utilization structure. In terms of spatial heterogeneity, the effect of the water resources tax policy on alleviating water poverty is stronger in central and eastern regions than in western regions. The conclusions of this study may, to some degree, serve as a basis to scientifically guide the implementation of China's water resources ‘fee to tax’ policy and, thus, effectively improve the level of water resources management.

Regarding the relationship between value, resources, and environmental issues, how to use the principle of economic leverage to manage the demand for agricultural water resources has received increasing research attention. Yet, due to the complexity of how the water economy is structured and to uncertainty in how setting an agricultural water price will affect water demand responses, it is still unclear how to determine a reasonable way to charge for agricultural water. This study investigates the impact of water prices on regional cropping structure, irrigation water use, and environmental sustainability under different increasing price scenarios, using a positive mathematical programming (PMP) model based on GAMS software. The model was run and calibrated using 427 field survey data from the pilot areas in the Wei River Basin for the 2022 crop year. These pilot areas have been selected by local government for comprehensive reform to agricultural water pricing. Our results show that increasing the agricultural water price leads to changing of crop planting structure in the study area and to increase of water price elasticity. Furthermore, when the water price rose 200% and 400%, the pesticide input in site A decreased by 1.71% and 3.40%, respectively, and the fertilizer input in site B decreased by 1.05% and 2.03%, respectively. Therefore, our results support the positive role of Chinese authorities implementing water price reform policies in the Wei River Basin. The main contribution of this study lies in the use of a mathematical planning model to empirically analyze the response patterns of agricultural production to changes in water prices. The findings offer a valuable reference for China in establishing rational ranges for water price variations.
