中文摘要:为探究劳动力流动、服务外包及二者的交互项等因素对技术效率的影响,以河南省2 058份农户的微观调研数据为例,应用超越对数随机前沿生产函数对小麦种植户的技术效率进行测算,并运用CLAD模型进行实证研究。结果显示:1)样本农户平均技术效率为 0.707,且农户之间技术效率具有较大异质性和不均衡性;2)劳动力流动对技术效率有显著的负向影响,近距离流动下的粮食技术效率大于远距离流动下的粮食技术效率;3)服务外包对技术效率有显著的正向影响,耕种收全部关键环节外包的技术效率大于不外包或者部分关键环节外包的技术效率;4)劳动力流动和服务外包具有相互依存和相互作用的链接关系,劳动力流动有利于推动服务外包程度,服务外包又反过来能够刺激劳动力流动,并能够抑制劳动力流动对粮食技术效率带来的损失。鉴于此,提出发展地方产业增加就近就业机会、加大关键环节外包程度和土地流转等政策建议。

Labor mobility, service outsourcing and grain technology efficiency: Based on an empirical study of 2 058 farmers in Henan Province
Abstract:In order to explore the impact of labor mobility, service outsourcing and their interactions on grain technical efficiency, a micro survey data of 2 058 farmers in Henan Province is taken as study case. The transcending stochastic frontier production function is used to measure the technical efficiency of wheat growers, the CLAD model is adopted for empirical research. The results show that: 1)The average technical efficiency of the sample farmers is 0. 707, and there is a large heterogeneity and imbalance in technical efficiency among different farmers; 2)Labor mobility has a significant negative impact on technical efficiency. The technical efficiency of food obtained by short-distance labor mobility is greater than that obtained by long-distance labor mobility; 3)Service outsourcing has a significant positive impact on technical efficiency. The technical efficiency obtained by outsourcing all key links of farming and harvesting by farmers is greater than the technical efficiency obtained by outsourcing some key links; 4)Labor mobility and service outsourcing have an interdependent and interactive link relationship and Labor mobility is conducive to promoting the degree of service outsourcing. Service outsourcing can in turn stimulate labor mobility and restrain the loss of food technology efficiency caused by labor mobility. In view of this, policy recommendations such as developing local industries, increasing nearby employment opportunities, increasing the degree of outsourcing of key links, and land transfer are put forward.
