| 目的 探究农户参与土地托管如何影响农业生产效率，以及绿色技术采纳行为如何在土地托管和生产效率间起作用，从而对有关土地托管研究的理论给予补充。方法 文章以河南省305个农户数据为基础，运用DEA模型、倾向得分匹配法及中介效应检验研究了土地托管、绿色技术采纳行为对农业生产效率的影响效果。结果 （1）土地托管比未托管农户农业生产效率平均高0.287，土地托管能有效提升农户的农业生产效率；（2）绿色技术采纳行为在土地托管对农业生产效率影响中起明显的中介作用，中介效应占比48.39%；（3）土地托管加剧了农户内部生产效率差异，土地规模和兼业化的差异是导致农业生产效率不同的主要原因。结论 政府实施推广、补贴等政策应向土地托管倾斜，提升农户绿色技术采纳意愿，更好地发挥土地托管带动小农户提高效率，保障粮食安全问题，提高农业现代化水平。 |

| Abstract: |
| This research is intends to explore how farmers' participation in land trusteeship affects agricultural productivity, and how green technology adoption plays a role in the relationship between land trusteeship and productivity, so as to supplement the theories research of land trusteeship. Based on the data of 305 rural households in Henan province, the effects of land trust and green technology adoption on agricultural production efficiency were studied by using DEA model, propensity score matching method and intermediary effect test. The results showed that: (1) The average agricultural productivity of land trusteeship was 0.287 higher than that of non-trusteeship farmers, and land trusteeship could effectively improve the agricultural productivity of farmers; (2) The adoption behavior of green technology played an obvious mediating role in the influence of land trusteeship on agricultural production efficiency, and the mediating effect accounted for 48.39%; (3) Land trustement intensified the differences in farmers' internal production efficiency, and the differences in land scale and part-time employment were the main reasons for the differences in agricultural production efficiency. Therefore, government implementation of promotion, subsidies and other policies should be tilted towards land trusteeship, enhance farmers' willingness to adopt green technology, better play land trusteeship to drive small farmers to improve efficiency, ensure food security, and improve the level of agricultural modernization. |
