Abstract : This study investigated the practices of cinnamon production by ethnic minority groups in the Thai Nguyen province. The study surveyed data from 343 cinnamon production households, using reliable analysis tools such as Cronbach's Alpha coefficient, EFA exploratory factor analysis, and linear regression models. Research results have identified 8 factors and the level of influence of each factor on the development of local cinnamon production. These factors include education level, age of the household head, government support policies, experience of the household head, capital, economic benefits, and science and technology. The study results also showed four factors greatly affect the development of cinnamon production in farmer households. They are capital, financial benefits, policy support, and the education level of the household. The magnitude of the standardized level of impact in descending order of the independent variables on the dependent variable of cinnamon production development (PD) is as follows: capital (β = 0.320), economic benefits (β = 0.294), Support policies (β = 0.252) and education level of the household head (β = 0.237). To limit the negative impacts of the above 4 factors, farmers need to change their awareness, boldly borrow capital to invest, and regularly update new knowledge. Local authorities issue specific policies for cinnamon households and coordinate closely and effectively with farmers.
