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.
