本文利用全国7省3684户农户的微观调查截面数据，运用SBM模型测度农户农业绿色生产效率，从产权细部视角实证检验土地托管服务的绿色赋能效应与作用机制。结果表明：土地托管服务通过产权细部的拆解与专业化匹配，显著提升了农户农业绿色生产效率，且该影响呈先升后降的倒U型特征；机制分析表明，要素投入结构优化与期望产出增加是其主要作用路径；异质性分析显示，粮食主产区、销售类及产后环节的托管服务的绿色增效效应更为显著，而完善的产权制度环境可进一步放大该绿色增效效应。

Based on the cross-section micro-survey data of 3684 farmers from seven provinces across China, this paper measures farmers’ agricultural green production efficiency by using the SBM model, and empirically examines the green empowerment effect and mechanism of land trusteeship services from the perspective of property rights details. The results show that land trusteeship services significantly improve farmers’ agricultural green production efficiency through the decomposition and professional matching of property rights details, and this effect exhibits an inverted-U pattern that first rises and then falls. Mechanism analysis indicates that the optimization of factor input structure and the increase in desired output are the main pathways of this effect. Heterogeneity analysis reveals that the green efficiency-enhancing effect is more significant in major grain-producing areas, sales-oriented trusteeship services, and post-production trusteeship services, and a sound property rights institutional environment can further amplify this effect.
