摘要 农机社会化服务是小农户有机衔接现代农业生产的重要方式,对推动乡村振兴具有重要意义。在理论分析农业补贴对农户购买农机服务影响的基础上,利用CLDS2014—2018年3期非平衡面板数据,使用面板ordered Logit随机效应模型、ERM模型和中介效应模型等计量手段,证实农业补贴能够显著促进农户购买农机服务,经过不同方式的稳健性检验和工具变量法消除内生性后,仍旧支持这一结论。异质性分析表明,农业补贴促进小规模、低收入和非粮食主产区内农户购买农机服务的作用更大。进一步的机制检验证明,农业补贴不仅能够显著促进农户转入土地,而且能够提升其信贷可得性并促使其将资金用于生产性投资,扩大实际种粮面积并缓解资金约束,因而能够促进农户购买农机服务。研究发现有助于理解农业补贴与农机服务购买行为之间的内在机制,为推广农业社会化服务过程中坚持并完善农业补贴政策提供启示。

Abstract: The socialized service of agricultural machinery is an important way for small farmers to organically connect with modern agricultural production, and is of profound significance for promoting rural revitalization. Based on the theoretical analysis of the impact of agricultural subsidies on farmers’ purchase of agricultural machinery services, this paper uses the third term unbalanced panel data of CLDS2014-2018, panel ordered Logit random effect model, ERM model and intermediary effect model to prove that agricultural subsidies can significantly promote farmers’ purchase of agricultural machinery services. And after different robustness tests and instrumental variable methods, this conclusion is still supported. Heterogeneity analysis shows that agricultural subsidies play a greater role in purchasing agricultural machinery services in small-scale, low-income and non-major grain producing areas. Further mechanism tests show that agricultural subsidies can not only significantly promote farmers to engage in agricultural production, but also enhance the availability of credit and be used for productive investment, expand the actual grain growing area and alleviate financial pressure. Thus, it can promote farmers to purchase agricultural machinery services. This study helps us to understand the internal mechanism between agricultural subsidies and the purchase of agricultural machinery services and provides inspiration for the government to improve agricultural subsidy policies in the process of promoting agricultural socialized services.
