水稻规模农户生产环节对机械化服务外包的选择

以浙江省3个县的148个样本农户调查数据为基础，通过构建多元线性回归模型对影响农户生产环节选择外包机械化服务的因素进行实证分析。结果表明:随水稻Oryza sativa栽培面积增加，生产环节中农户接受社会化服务概率先增大后减少，呈"倒U"型，存在明显的规模经济效应；户主年龄对接受机械化服务程度有显著的正向影响；农机手的经历、家庭拥有农机数量以及土地破碎化等因素对接受机械化服务有显著负向影响。在此基础上提出培育多种服务主体、鼓励土地整理、为机械化外包服务提供良好发展环境等政策建议。

Large rice farmer households'decisions on mechanic service outsourcing in rice production

Based on the survey data of 148 farmer households in 3 counties of Zhejiang Province, this study constructed a multiple linear regression model to make an empirical analysis of the factors influencing farmer households' decisions on mechanic services outsourcing in Oryza sativa production. The research showed that with the increase in the farming area of rice, farmer households'probability of accepting socialized services would increase first and then decrease, showing an inverted U curve and indicating an obvious economies of scale. Age had a significant positive impact on the degree of accepting mechanic services; whether the family members had experience of operating agricultural machines, the number of agricultural machines owned by the households, and the fragmentation of land had significant negative impacts on the acceptance of mechanic services. Based on our research, we proposed policy recommendations including cultivating multiple service organizations, encouraging land consolidation, and providing a good development environment for mechanic services outsourcing.
