Abstract

Vietnam’s seafood industry is one of the country’s most important export sectors, but it faces growing competition and stricter standards in major markets such as the United States and China. This study applies the Constant Market Share Analysis (CMSA) method to examine the factors behind changes in Vietnam’s seafood exports to these two markets during 2010–2022. The results show that export growth in recovery periods was mainly driven by market expansion and interaction effects, particularly in the U.S. market. However, the competitive effect is often negative, especially in China, suggesting limitations in product competitiveness. The findings also indicate that exports to China rely largely on market demand, while the U.S. market depends more on structural advantages that help sustain export performance. These results highlight the importance of improving competitiveness and increasing the share of higher value-added seafood products.
