中文摘要：

本文基于农户行为理论和行为经济学理论，构建了种植业技术密集环节外包的个体响应机理，分析外包认知、外包意愿与外包行为的影响关系，以及小麦生产过程中技术密集的播种、植保和追肥等三个环节外包行为之间的关系和影响因素。以河南和山西两省631户小麦种植户的调查数据为基础，采用Mv-probit模型和Poisson模型进行实证分析，研究结果表明：第一，农户在技术密集环节外包过程中，播种环节、植保环节和追肥环节之间存在正相关关系。第二，农户的外包认知直接影响外包行为，外包意愿也直接影响外包行为，同时，外包认知通过外包意愿间接影响外包行为。具体来看，农户对技术密集环节外包易用性认知越高，选择教术密集环节外包的概率越大；农户对技术密集环节外包有效性认知越高，选择技术密集环节外包的概率越大；农户外包意愿越高，选择植保环节和追肥环节外包的可能性也越大。第三，外出务工工资、小麦种植规模、户主年龄、户主受教育程度、小麦种植年限、技术培训是影响农户技术密集环节外包行为的重要影响因素。

英文摘要：

Based on the theory of farmer behavior and behavioral economics, this article sets out to construct wheat farmers＇ individual response mechanism in outsourcing technology-intensive processes, exploring the relationship between crop farmers＇ cognition and willingness of outsourcing and their outsourcing behaviors, as well as the determinants of outsourcing behaviors. The study uses a Multivariate Probit model and a Poisson model for analysis, employing survey data collected in 2015 from 631 wheat farmers in Henan and Shanxi Provinces. The results show that, firstly, there are obvious positive correlations among different technology-intensive stages of outsourcing behaviors for wheat growers. Secondly, the awareness of technology feasibility in technology-intensive stage and the awareness of effectiveness to outsourcing willingness have significant impact on outsourcing behavior of wheat growers. Thirdly, the main determinants ofoutsourcing behaviors of wheat growers in technology-intensive sectors include, among others, migrant workers＇ wage, operation scale of wheat farmland, the age and educational level of household heads, the years of planting wheat and participation in technical training.
