The purpose of this study was to analyze the production and marketing control effects of aqua-cultured flounder required for stable income growth of aqua-cultured household. We analyzed the supply and demand structure of cultured flounder using the partial equilibrium model approach. And we estimated the optimal yield of cultured flounder and analyzed the effect of marketing control through constructed model. The main results of this study are summarized as follows. First, the fitness and predictive power of the estimated model showed that the RMSPE and MAPE values were less than 5% and Theil's inequality coefficient was very close to 0 rather than 1. It was evaluated that the prediction ability of the aqua-cultured flounder supply and demand model by dynamic simulation was excellent. Second, dynamic simulation based on policy simulation was conducted to analyze the price increase effect of production and shipment control of cultured flounder. As a result, if the annual production volume is reduced by 1%, 5%, and 10% among 32,852~37,520 tons, it is analyzed that the price increase effect is from 1.2% to 12.5%. Finally, this study suggests that the production and marketing control can increase the price of aqua-cultured flounder in the market. In this paper, we propose a policy implementation of the total supply system instead of conclusions.

본 논문은 국내 양식 넙치 중장기 시장 규모 추정을 위해 구축된 수급전망모형을 개발한 내용과 이 모형을 이용하여 2015년-2017년 기간에 대해 시장 규모(수급 및 가격)를 예측한 내용을 소개하고 있다. 양식 넙치 수급전망모형은 단일품목 부분균형모형이며 동태 축차적 시뮬레이션 모형으로 개발되었고, 모형내 각 행태방정식은 계량경제학 방법을 이용하여 추정되었다. 중 장기 시장 규모 전망에 앞서 모형의 예측정확도는 RMSPE, MAPE, Theil의 불균등계수를 기준으로 검토되었다. 예측력 검토결과, 양식면적, 양성물량, 출하량, 도매가격은 모두 4% 이내의 양호한 오차율을 보였다. 국내 양식 넙치 시장 규모 전망결과, 생산량은 2015년 37,445톤, 2017년 42,561톤에 이를 것으로 전망되었고, 산지가격은 2015년 9,226원(1kg 기준), 2017년 10,191원될 것으로 전망되었다.
