【摘要】 大国小农背景下，农业社会化服务推动了小农与农业现代化生产体系融合，然而交易成本造成了效率损失。基于2022年陕西省农户调研数据，将小农户资本禀赋、农业社会化服务以及有为集体纳入统一的研究框架，并构建实证分析模型，探究其对生产效率的影响。研究表明：资本禀赋对生产效率的影响呈显著的倒“U”型关系，并且大部分农户处于左侧上升阶段；农业社会化服务通过替代效应和技术效应在资本禀赋对生产效率的影响中具有显著影响；有为集体从合理分配社会化服务增值效益出发，可以有效缓解交易成本的不利影响，即有为集体显著调节农业社会化服务对生产效率的影响。由此，提出通过加大农业社会化服务培育力度，规范市场运行，强化村集体介入管理，以缓解当前小农资本禀赋不足对生产效率的负向影响。更多还原

【Abstract】 Under the background of small farmers in large countries, agricultural socialization service promotes the integration of small farmers and agricultural modern production system, but the transaction costs cause efficiency loss.Based on the survey data of farmers in Shaanxi Province in 2022,capital endowment of small farmers, agricultural socialized services and productive collectivities are integrated into a unified research framework, and a multilayer regression model is constructed to quantitatively analyze their impact on production efficiency.The results show that the influence of capital endowment on production efficiency presents a significant inverted U-shaped relationship, and most of the farmers are in the left rising stage; social service has a significant impact on the effect of capital endowment on production efficiency through substitution effect and technology effect; Starting from the reasonable distribution of value-added benefits of social services, productive collectives can effectively alleviate the adverse impact of transaction costs, that is, productive collectives can significantly adjust the impact of social services on production efficiency.Therefore, it is proposed to strengthen the cultivation of social services, standardize the market operation and strengthen the village collective intervention management, so as to make up for the negative impact of the lack of capital endowment of smallholders on the production efficiency.更多还原
