This paper addresses the development on supply-demand outlook model of Jeju winter radish and introduces a projection of supply-demand and market prices during 2014-2018 using the model. The supply-demand outlook model is specified as a partial equilibrium model of Jeju winter radish. Each equation in the model is estimated by using the econometric techniques. A review of the model stability is also carried out by the references based on RMSPE, MAPE, and Theil's inequality coefficients. According to the reference of RMAPE, the error rates of the forecasting values of the cultivation ares, production quantity, and consumption quantity show less than 4% and the error rate of market price is below 10%. The cultivation area and production quantity are projected respectively to be increased to 6,650ha and 433,310MT in 2018.

The purpose of This paper is to address the development on supply-demand outlook model of aqua-cultured korean Flatfish and introduces a projection of supply-demand and market prices during 2015-2017 using developed model. The supply-demand outlook model is composed as a partial equilibrium model of Korean Flat fish. Each equation in the model is estimated by the econometric techniques. A reviews of the demand-outlook model stability is also carried out by the references based on RMSPE. MAPE, and Theil's inequality coefficients. According to the reference of RMSPE, the error rates of the forecasting values of the aqua culture area, culturing quantity, production quantity, market price show less than 4%, The production quantity and farm price are predicted respectively to be 42,561MT and 10,191KW per kg in 2017.
