The study uses a binary regression model, rational action (TRA) theory, and the theory of intentional behavior (TPB). The study's objectives are to determine the factors affecting the intention to choose the farming model of crab - shrimp - rice of farmers in Kien Giang province. The results of the analysis of 102 extensive crab-shrimp-rice farming households showed that male respondents accounted for 82.4%, the average age of the household head was 51 years old, the average education level of the household head was 7th grade. The average number of years of experience of the household head was 10 years, the average area of the household was 2.8 ha. The results of binary regression analysis showed that 9 variables (education, training, experience, area, salinity, increased profit, model fit, impact of people around, and model implementation ease) influenced the intention to choose the farming model of crab-shrimp-rice of farmers. From the research results, the following solutions were proposed: Farmers’ management of all kinds of risks during the productionand consumption of shrimp and rice,regular monitoring of weather/environmental studies or forecasts,selection of seed sources and inputs (feed, lime, antibiotics) from reputable establishments,participating in local trainingandsqueezing the shrimp back before putting them in the pond.
