We analyze the driving mechanism of the River-Director System reform in the article. Using the ordered probit model, the effect of the River-Director System policy was evaluated by observing the monthly water quality data of 170 water areas along the boundary of the Yangtze River system. It determines that the driving force of the local government’s basin governance under the river system is mainly the top-down policy directives and that the driving path is effective synergy, rights, and diffusion in the article. We find that the upstream provinces and municipalities that implemented reforms have significantly improved the water quality of the waters in the border basin, compared with the provinces and cities that have not implemented the reform of the river system and the river basins that have implemented policy reforms but are located in the lower reaches of the rivers. At the same time, the city’s reforms have significantly improved the quality of the junction basin water body. The implementation of the River-Director System has reduced the occurrences of local pollution emission and improved the water quality of the provincial boundaries through sewage treatment. We further validate the robustness of the basic conclusions by deleting special samples and changing the window type and other robust tests. Finally, through monthly examinations on the implementation of the policy, it finds that the effectiveness of the policy reform became more apparent in the eleventh month.
