Although the clarification of property rights for agricultural land has the potential to enhance agricultural production efficiency and support its sustainable growth, this goal may not always be met in reality. As a result, the emphasis of this study is on the elements that affect agricultural output. It also examines how the stability of land rights affects agricultural production efficiency and, most importantly, how the heterogeneity of farmers' perspectives affects this process. Through the empirical test using the data of farmers in Henan Province, the largest wheat area in China, the results show that: (1) The farmland confirmation policy significantly promotes the improvement of the pure technical efficiency of agricultural production, a series of robustness tests, and the treatment of endogenous problems, which also confirmed the robustness of the results. (2) In the allocation of factors, agricultural investment and credit acquisition have been proved to be important influencing mechanisms, while labor and land transfer have not played a mechanistic role. (3) Heterogeneity analysis shows that the self-service of farmers choosing to purchase agricultural machinery is more efficient than purchasing outsourcing services; The agricultural production of farmer households without hired workers has a significant technical efficiency, but the impact on farmer households with hired workers is not significant; for farmer households with agricultural insurance purchase behavior, purchase willingness, and planting and breeding advantages, the farmland ownership confirmation policy can play a more important role in promoting the pure technical efficiency of agricultural production; The promotion effect of the farmland right confirmation policy on the pure technical efficiency of agricultural output is strongest when there is a smaller level of farmers operating on a part-time basis and when more farmers prioritize profit maximization as the production goal. Corresponding policy recommendations are made at the conclusion of the study in light of the conclusions mentioned.
虽然明晰农地产权有助于提高农业生产效率，支撑其可持续增长，但这一目标在现实中未必总能实现。因此，本研究重点关注影响农业产出的要素，检验土地产权稳定性如何影响农业生产效率，以及农民观念的异质性如何影响这一过程。利用中国最大小麦产区河南省农户数据进行实证检验，结果表明：（1）农地确权政策显著促进了农业生产纯技术效率的提升，一系列稳健性检验及内生性问题处理也验证了结果的稳健性；（2）在要素配置上，农业投资和信贷获取被证明是重要的影响机制，而劳动和土地流转没有发挥作用机制；（3）异质性分析表明，农民选择自营购买农业机械比购买外包服务更有效率；无雇工农户的农业生产具有显著的技术效率，但对有雇工农户的影响不显著；对于有农业保险购买行为、购买意愿和种养优势的农户，农地确权政策可以在促进农业生产纯技术效率方面发挥更重要的作用；当农民兼业程度较小、以利润最大化为生产目标的农民占比更高时，农地确权政策对农业产出纯技术效率的促进作用最强。根据结论提出了相应的政策建议。
