| 为探索粮食商品化对农户施肥行为的影响机制，本研究基于2020年中国乡村振兴调查（CRRS）的631户农户数据，利用最小二乘法模型和中介效应模型分析粮食商品化、要素配置对农户施肥行为的影响，并进一步分析粮食商品化对不同类型农户施肥行为的影响。实证结果显示：粮食商品化与农户施肥行为之间存在倒“U”型关系，粮食商品化率 49.74% 为其转折的临界点。机械化程度在粮食商品化影响农户施肥行为的关系中发挥机制作用。在粮食商品化率不断上升的过程中，机械化程度的提高更有利于农户施肥行为减量化。粮食商品化与不同类型农户的施肥行为之间均存在倒“U”型关系，不同类型农户间的拐点值存在差异。其中生产型、自给型、生活型三类农户的粮食商品化率拐点分别为 53.23%、45.29%、50.73%。研究表明，提高粮食商品化率、提高机械化程度和加强相关培训等都有利于推动农户施肥减量化，有助于农业绿色发展。 |

| In order to explore the influence mechanism of grain commoditization on the fertilizer application behavior of farm households, this study was based on the data of 631 farm households from the 2020 China Rural Revitalization Survey（CRRS）, and analyzed the influence of grain commoditization and factor allocation on the fertilizer application behavior of farm households by using the least-squares model and mediated-effects model, and further analyzed the influence of grain commoditization on the fertilizer application behavior of different types of farm households. The empirical results showed that：there was an inverted U-shaped relationship between grain commercialization and fertilizer application behavior of farmers, and its turning point was 49.74%. The degree of mechanization played a mechanism role in the relationship between grain commercialization and farmers ′ fertilizer application behavior. In the process of rising grain commercialization, the increase of mechanization degree was more conducive to the reduction of fertilizer application behavior of farmers. There was an inverted U-shaped relationship between grain commercialization and the fertilizer application behavior of different types of farmers, and there were differences in the inflection point values among different types of farmers. Among them, the inflection points of production-type, subsistence-type and livelihood-type farmers were 53.23%, 45.29% and 50.73%, respectively. The study shows that increasing the commercialization rate of grain, improving mechanization and strengthening related training are all conducive to promoting the reduction of fertilizer application by farmers and contributing to the green development of agriculture. |
