| Outline of Final Research Achievements |
This study examines the implementation system and supply-demand adjustment function of staple rice after the abolition of the national government's allocation of production quantity targets for staple rice, and clarifies changes in paddy field use and cropping patterns from an actual survey.
The production adjustment was abolished in 2018, and since 2019, the area of staple rice planted nationwide has decreased significantly. On the one hand, the area of unplanted land has expanded, and paddy field land use has receded due to the shift in production adjustment policy. In addition, amid declining demand for rice, a shift from staple rice to non-staple rice is gradually progressing on the basis of arable-livestock partnerships. Thus, changes in paddy field utilization have been observed. It became clear that in order to enhance the effectiveness of rice production adjustment, it is necessary to create conditions for stable production of crops other than staple rice.

本研究の学術的意義は，第一に，国による生産数量目標の配分の廃止による影響について，先行研究の理論的予測はあったものの，実証分析の実施はおこなわれていない段階において，本研究は理論と実証の乖離を埋め，実証に基づいた考察を進めたという意義を有する．第二に，生産数量目標の配分の廃止という生産調整の見直しによる影響分析を，実態調査を通していち早く明らかにし，地域を比較しながら面的・総合的に分析をすすめ，生産調整の実効性を高める諸条件を明らかにしたという意義も有するものである．
