| 摘要: |
| 农业生产托管是解决粮农既要种地又想务工的双重矛盾的重要手段，针对其对粮农家庭收入的影响及其作用机制的环节异质性尚不清楚这一问题，构建“农业生产托管—要素替代—粮农家庭收入”的理论框架，基于中国11省44县的2 060份粮农数据，采用内生转换模型和中介效应模型，深入剖析农业生产托管对粮农家庭收入的影响及其内在机制。结果表明：1）粮农的农业生产托管决策受托管特征、种植特征等内外部因素影响。2）农业生产托管可以优化粮农家庭收入结构，提高收入水平。其中，工资性收入的平均处理效应>粮食种植性收入>转移性收入。3）农业生产托管从劳动力分工和物质资本配置2个维度促进粮农增收，且存在环节异质性，其中，劳动力分工的中介效应>非劳动力要素配置。耕地、收储等劳动密集型环节托管主要经优化劳动力分工提高粮农收入，防治等技术密集型环节则主要通过优化物质资本配置促进增收。 |

| Abstract: |
| Agricultural production trusteeship is an important means to solve the dual contradiction between farmers who want to farm and work at the same time， and its impact on farmers’ household income and the heterogeneity of its mechanism of action are still unclear. To address this issue， a theoretical framework of “agricultural production trusteeship-factor substitution-smallholders’ income” is constructed. Based on 2 060 samples from 44 counties of 11 provinces in China， the impact of agricultural trusteeship on the household income and its internal mechanism are analyzed. The results show that： 1） The agricultural production trusteeship is affected by internal and external factors such as trusteeship characteristics and planting characteristics； 2） Agricultural production trusteeship optimizes the income structure and increase the level of household income. Among them， the average treatment effect of agricultural production in descending order is wage income > planting income > transfer income； 3） Agricultural production trusteeship promotes the increase of agricultural income through two dimensions of labor division and material capital allocation， and there is heterogeneity in links. Among which the mediating effect from high to low is labor division > material capital allocation. The trusteeship of labor-intensive links such as cultivated land and storage mainly increases the income of farmer by optimizing the labor division， while technology-intensive links such as prevention and control mainly promote the increase of agricultural income by optimizing the material capital allocation. |
