In order to solve the global marine ecological environment problems and ensure their own marine strategic interests, we should participate in the global marine ecological environment governance in an all-round way. There are still some problems in the evaluation system, supervision mechanism, and performance evaluation of the marine ecological environment. Considering the impact and analysis on the ecological environment in the effect of marine governance, this paper puts forward the performance analysis of marine ecological environment governance based on DPSIR (Drive Pressure State Impact Response) and entropy weight TOPSIS model and constructs the performance index evaluation system of marine ecological environment governance combined with the current situation of marine ecological environment governance. Using entropy TOPSIS (technique for order performance by similarity to ideal solution) model and geographic detector, this paper explores the influencing factors of governance performance. From the perspective of marine ecological environment governance effect, the governance effect is good. The influence of pressure factors such as ecological environment, population, and economy is generally large. The main causes of marine environmental pressure are the massive amount of industrial wastewater, the utilization of water resources in coastal areas, and the employees involved in the sea. Through the factor detection method of geographic detector, the strength calculation of the three criteria of pressure-state-response which affect the performance level of marine environmental governance is carried out, and the pressure layer index, state layer index, and response layer index have good response. In marine science and technology innovation ability, government investment in marine construction has a significant impact on environmental governance performance.
