Abstract: The implementation effect of the Ten-year fishing ban policy is directly related to whether the goals can be successfully achieved proposed by the central government, including allowing fishermen "retreating fishing", "living stabilization" and "getting richer". Based on the survey of 14 counties in Hunan Province, a comprehensive benefit evaluation index system was constructed which included ecology, economy and society indicators. The entropy weight-TOPSIS model was used to evaluate the implementation effect of the fishing ban policy. This study found that: (1) In the short term, the economic and social benefits of the policy accounted for 85% of the total benefits, and the ecological benefits only accounted for about 15%. Achieving good ecological benefits required long-term persistence and more efforts. (2) Only counties that performed well both in ecological, economic and social benefits could achieve comprehensive benefits satisfactory. Counties with poor efficiency in individual indicators failed to achieve a high comprehensive benefit score. (3) Increasing the expenditure for the fishing ban, transferring employment training, and publicity of fishing ban could improve the comprehensive benefit greatly.
