农户分化、技术约束与耕地保护技术选择差异——基于不同约束条件下的农户技术采纳理论分析框架

在不完全要素市场和农户分化背景下,探索不同类型农户、耕地保护技术约束与技术选择之间内在行为逻辑,以期为保障我国耕地质量可持续发展提供参考。利用Probit和Logit方法,通过微观数据剖析不同类型农户技术选择意愿、行为逻辑及不同约束条件下的技术选择差异。研究表明：纯农户、I类兼业户和II类兼业户在耕地保护意愿方面具有统一性,但随着非农收入的增加农户耕地保护意愿逐渐降低;在行为逻辑方面,异质性农户耕地保护技术选择上差异显著,不同类型农户的禀赋特征与不同耕地保护技术间存在非对称性和偏差,主要受不同技术属性和风险偏好的约束。因此在耕地保护技术实施与推广应用时,应当更多地考虑不同农户禀赋优势与农户风险偏好程度。

Differentiation of farmers,technical constraints and the differences of cultivated land protection technology selection: A theoretical analysis framework of farmer households' technological adoption based on different constraints

Under the background of incomplete factor market and farmers' differentiation, this paper explores the internal behavior logic between different types of farmers, technical constraints of cultivated land protection and technical choices, in order to provide reference for the sustainable development of cultivated land quality in China. In this paper, probit and logit methods are used to analyze different types of farmers' willingness to choose technology, behavior logic and differences in technology selection under different constraints. The results show that: pure farmers, class I and class II households have unity in farmland protection intention, but with the increase of non-agricultural income, farmers' farmland protection intention gradually decreases. In the aspect of behavioral logic, there are significant differences in the choice of different types of farmers' cultivated land protection technology. There are asymmetry and deviation between different types of farmers' endowment characteristics and different cultivated land protection technology, which are mainly constrained by different technical attributes and risk preferences. Therefore, in the implementation and application of farmland protection technology, more consideration should be given to different farmers' endowment advantages and risk preference.
