Abstract: The introduction of the river chief system is an important measure for our country to manage and harness the river. With the further development of the river chief system, many potential problems have gradually emerged. In order to solve the problems and ensure the long-term implementation of the system, the establishment and improvement of the assessment mechanism is crucial. From the perspective of the new public service theory, taking Nanjing as an example, the existing problems in the assessment of river chief system are analyzed, and the corresponding countermeasures are put forward.
