The organization ,programs and operation mechanism are still developing while electronic supervision is implementing .This paper discusses the strengths and weaknesses of current operation mode of electronic supervision and proposes a coordinated operation mode of command centre based on the theory of electronic supervision ."Ship violation rate""ship violation rate of remote correction"and"maritime accident rate"are selected as the evaluation indicators ,and an efficiency analysis is conducted based on hypothesis testing .The result shows that maritime supervision effectiveness value increases from 0 .894 to 0 .998 after the implementation of electric supervision .In the future ,the data will be col‐lected and saved in a central system with the development of electronic supervision ,and different modes can be evaluated . The coordinated operation mode can improve supervision efficiency and help to standardize the implementation of electron‐ic supervision ,which plays an important role in maritime supervision .
