In December 2017, a pilot program on water resources tax reform was launched in Dezhou Municipality. Focused on the relevant policies of water resources tax in Shandong Province, the Program was expected to explore and guide the rational allocation and utilization of water resources via tax leverage. Since then, it established a coordination mechanism for water resource tax collection in Dezhou, and improved the water intake metering system. Remarkable economic benefits have been achieved, the structure of water consumption has been optimized, and water resources management has been effectively enhanced. This paper analyzes the existing deficiencies in relevant work, and explores to exert the role of tax leverage continuously under the new policies for the water resource tax pilot, promote water-saving renovation of enterprises, and further facilitate the conservation and protection of water resources.
