This paper studies the VTS performance in China and establishes an evaluation system based on the theory of “4E”.The performance of VTS in China is evaluated using the cloud model.The evaluation results show that VTS plays an important role in increasing traffic flow and improving the society image of maritime sector；the internal organization efficiency of VTS is significantly higher than its external supervision service efficiency；the efficiency index,effectiveness index and fairness index are better than the economic index in the evaluation results of VTS performance；and the qualitative indices have more randomness and fuzziness than quantitative indices in the application of cloud model.It concludes that the evaluation system and the cloud model are effective in the evaluation of VTS performance in China.
