본 연구는 장기 밤수급 예측과 국내외 시장여건 변화가 국내 밤시장에 미치는 영향을 분석하기 위하여 수행되었다. 이를 위해 본 연구에서는 생밤시장과 깐밤시장을 상호 수직적으로 연결하는 부분균형모델을 개발하였다. 개발된 모델의 내생변수에 대한 예측능력을 측정하기 위하여 1990년부터 2003년까지 사후예측을 실시하였다. 전반적으로 신규재배면적 및 폐기면적을 제외하고는 모든 내생변수들에 대한 모델의 예측오차가 낮았다. 수급예측 결과 국내 생밤생산량은 2005년에 76,447톤에서 2020년에는 76,286톤으로 약간 감소할 것으로 예측되었으며, 일본으로 수출되는 깐밤의 양은 지속적으로 감소할 것으로 예측되었다.

This study was carried out to forecast long-term supply and demand of chestnut and to analyze the impacts of change in the environment of domestic and international chestnut markets. For these ends, the study developed a partial equilibrium market model, in which in-shelled chestnut market was vertically linked to shelled chestnut market. To examine the predictive ability of the model for the endogenous variables ex-post simulation was run for the period 1990 through 2003. In general, all endogenous variables reproduced the historical trends during the period except for disuse areas and newly established areas. The results of forecasting supply and demand show that domestic in-shelled chestnut production is estimated to decrease slightly from 76,447 ton in 2005 to 76,286 ton in 2020 and that exports of shelled chestnut continue to be decreased.
