This study analyzed the causality and asymmetric price transmission(APT) phenomenon among import, producer, wholesale, and retail prices of Chub Mackerel(Scomber japonicus). Chub Mackerel is one of major fish species in production and consumption in Korea. Meanwhile, the problem of rising retail prices has recently emerged, the research on the price structure of Chub Mackerel is needed. In the analysis, APT was estimated using the Nonlinear Autoregressive Distributed Lag(NARDL) model. As a result, the import price had a significant effect on retail price and asymmetric price transitions occurred overall at all distribution stages. In particular, a total of 12 APT phenomena were found, and front distribution stage was sensitive to the decrease in the price of the rear distribution stage and the rear distribution stage was more sensitive to the increase in the price of the front distribution stage.
