The objective of this research was to measure the competitive level of cultivated banana producers in Isaan region. Competition was measured via an ability of mark-up pricing by calculating the Lerner index. Research samples were the cultivated banana growers from Ban Muang and Ban Wang Mon communities, Sangkom district, Nong Khai province. Purposive sampling method was used to select 40 samples from both communities. There were 3 key results. First, overall, the Lerner index indicates that the growers competed in monopolistic market, and their profitability varied because of cost differentiation in each grower. Second, the competitive level in Ban Muang was higher than Ban Wang Mon. Third, 10 out of 40 growers had their marginal cost exceeding the selling price. They did not acknowledge this loss because their opportunity cost of labor was not counted into production. These results entailed two recommendations. First, there should be an advice on cost accounting including financial and opportunity cost of labor. Second, as the higher cost of growing, farmers should seek alternative option such as selling leaves and processing banana, aside from selling only fruits, to increase their income.
