Abstract

農業者戸別所得補償制度は,所得支持を目的とするものとしては,日本で初めての本格的な直接支払いである.しかし,日本稲作の生産性向上が求められる中で,戸別補償制度の導入が稲作生産性に及ぼした影響を実証的に解明した先行研究は見当たらない.また,戸別補償制度導入の影響には農家の規模や時期による違いがみられた可能性があり,その実証は直接支払いの効果的・効率的な運用のために重要である.そこで本稿では,戸別補償制度の導入が農家の稲作の全要素生産性水準に及ぼした影響を,特に影響の規模間・時点間の違いに注目して実証的に解明することを目的とする.傾向スコアマッチングと差分の差分法を組み合わせた分析の結果,作付面積1 ha 以上の農家については,特に戸別補償制度の導入当初にあたる2011 年においてのみ,稲作の全要素生産性水準に対し正の影響を有していた可能性が示された., The Japanese government implemented an extensive direct payment program to supportfarm income in 2010. However, no previous study has empirically examined the impact of the program implementation on rice productivity, and such an examination is essential because the current demand exists for increased productivity in rice production in Japan. Furthermore, the impacts may vary depending on the farm scale and time point. This empirical study examines the impact of program implementation on farmleveltotal factor productivity (TFP) level in rice production, focusing on the differences across farm scales and time points. Based on the results of combined propensity score matching and difference-in-differences analysis, it appears that program implementation had a positive impact only on larger farms, especially at the beginning of program implementation.
