| 探究农机社会化服务对粮食生产技术效率的影响,对于粮食保供具有重要意义。基于随机前沿生产函数法和内生转换模型,利用豫、鲁、冀、陕农户数据,测算了农机社会化服务对粮食生产技术效率的影响。结果表明,面对潜在道德风险以及疫情引起的服务价格升高等不利条件,农机社会化服务对农户粮食生产技术效率依旧具有正向影响,主要由技术引进、要素替换以及参与分工发挥了积极作用。环节异质性分析表明,机播、机收、机耕以及管理环节服务对技术效率的正向作用依次减弱,影响差异主要与农机社会化服务使用率的环节差异和各环节农机装备发展水平有关。规模异质性分析表明,农机社会化服务对经营范围0-0.67hm2、1.33hm2以上、0.67-1.33hm2农户粮食生产技术效率的促进作用依次减弱差异主要与农户服务使用量的变化和规模经济效应的发挥有关。最后提出要加快农机社会化服务全面、均衡发展,提升农机装备研发、制造和应用水平,持续推动农业适度规模经营。 |

| Abstract: |
| It is of great significance to explore the impact of agricultural machinery socialization services on the technical efficiency of food production. Based on the stochastic frontier production function method and endogenous transformation model, the impact of agricultural machinery socialization services on the technical efficiency of grain production was measured by using the data of farmers in Yu, Lu, Hebei and Shaanxi. The results show that in the face of potential moral hazard and the increase in service prices caused by the epidemic, the socialization of agricultural machinery services still has a positive impact on the technical efficiency of farmers'' food production, mainly by technology introduction, factor replacement and participation in the division of labor. The analysis of link heterogeneity shows that the positive effect of machine broadcasting, machine harvesting, machine farming and management services on technical efficiency is weakened in turn, and the difference in influence is mainly related to the difference in the utilization rate of agricultural machinery socialization services and the development level of agricultural machinery equipment in each link. The analysis of scale heterogeneity showed that the promotion effect of agricultural machinery socialization services on the technical efficiency of food production of farmers with a business scope of 0-0.67hm2, 1.33hm2 or more, and 0.67-1.33hm2 weakened sequentially, and the difference was mainly related to the change of farmers'' service usage and the exertion of economies of scale. Finally, it is proposed to accelerate the comprehensive and balanced development of agricultural machinery socialization services, improve the research and development, manufacturing and application level of agricultural machinery equipment, and continue to promote the moderate scale of agricultural operation. |
