基于2012-2016年日本水稻农场的平衡面板数据集，分析了直接支付对日本水稻收入变化的影响。首先，通过方差分解，分析了收入构成因素对稻米收入波动的贡献以及直接支付减少的影响。其次，稳健回归技术被用来衡量直接支付和大米收入波动之间的相关性。本文的创新之处在于，通过对日本的直接支付对收入变动性的影响进行回归分析，对支付的影响进行了分解。这与关于这一专题的现有文献形成鲜明对比，现有文献主要侧重于欧洲联盟国家。本文讨论了直接支付的减少在多大程度上增加了收入的可变性。结果表明，直接支付降低了日本大米收入的波动性。事实上，在控制了各种农场特征后，我们发现与水稻生产相关的直接支付金额与水稻收入波动性之间存在负相关关系。最后，研究结果表明，当大米价格下降时，减少直接支付会增加大米收入的波动性。
The effects of direct payments on rice income variability in Japan are analysed based on a balanced panel dataset of Japanese rice farms for 2012–2016. Firstly, the contribution of income components to rice income variability and the effects of a direct payment reduction are discussed by applying variance decomposition. Secondly, robust regression techniques are used to measure the correlation between direct payments and rice income variability. The originality of this paper is that it disaggregates the effects of payments using a regression analysis of the effects of direct payments on income variability for Japan. This contrasts with the existing literature on this topic, which has largely focused on European Union countries. This paper discusses to what degree the reduction in direct payments increases income variability. The results reveal that direct payments decrease Japanese rice income variability. Indeed, after controlling for various farm characteristics, we find a negative relationship between the amount of direct payments linked to rice production and rice income variability. Finally, the results suggest that reducing direct payments when the rice price is falling would increase rice income variability.
