基于中介效应的农户分化对耕地保护行为的影响

Impact of rural-household differentiation on cultivated land protection behavior based on intermediary effect

厘清农户参与耕地保护的行为逻辑对提升耕地质量、增加有效耕地面积具有重要意义。基于武汉城市圈的483份农户调查问卷,以耕地价值认知为中介变量,采用中介效应模型探究农户分化对耕地保护行为的具体作用机制。结果表明:农户分化对耕地保护行为的影响可以通过作用于耕地价值认知这一中介变量实现,在较高的耕地价值认知水平下,农户分化对耕地保护行为的负向影响效应将会减弱;非农兼业带来的收入增加会提高劳动力被资本替代的可能性,这使得农户分化对于劳动偏向型保护行为的负向影响效应要大于资金偏向型保护行为。据此认为,应大力推广资金偏向型耕地保护措施,加大对耕地多功能价值的宣传力度。

Clarifying the behavior logic of farmers participating in cultivated land protection is of great significance to improving the quality of cultivated land and increasing the area of effective cultivated land.Based on 483 questionnaires in Wuhan urban circle,by taking cultivated land value cognition as an intermediary variable,the mediating effect model was used to explore the specific mechanism of rural-household differentiation on cultivated land protection behavior.The results showed that the impact of rural-household differentiation on cultivated land protection behavior could be achieved by acting on the intermediary variable of cultivated land value cognition.At a higher level of cultivated land value cognition,the negative effect of rural household differentiation on cultivated land protection behavior would be weakened.The increase in income from non-farm employment would increase the possibility of labor force being replaced by capital,so the negative effect of rural-household differentiation on labor-biased protection behavior was greater than that on capital-biased protection behavior.Therefore,it was necessary to vigorously promote capital-biased cultivated land protection measures and increase the propaganda of the multi-functional value of cultivated land.
