农户绿肥种植决策行为及其影响因素——基于二元Logistic模型和南方稻区506户农户的调查

以南方稻区农户农田轮作绿肥为例,基于506户农户微观调研数据,对其绿肥种植决策行为进行二元Logistic分析。结果表明:从农户意愿来看,在充分尊重农户追求个人或家庭效用最大化的前提下,农田引入绿肥进行土壤肥力提升和生态环境保护这一绿色农业发展模式能够得到多数农户的支持。从各因素的影响机制来看,农户年龄、是否为村干部、家庭收入、农户对绿肥种植的社会和生态福利认知水平以及外部因素是影响其决策行为的重要因素,相对于个体特征和家庭禀赋,外部因素对农户绿肥种植决策正向促进作用更明显,尤其是政策宣传和种植补贴影响十分显著。据此,提出应充分尊重农户意愿,保障其追求个人或家庭效用最大化的权利;加大政策宣传力度,提高农户对绿肥种植的综合福利认知;统筹整合各方资源,加强绿肥示范基地建设;完善生态补偿机制,提高农户绿肥种植补贴标准。

Farmers' decision-making behavior of green manure planting based on binary logistic model: A case study of 506 households in southern China

Taking green manure rotation in farmers'' farmland in southern rice region as an example,binary logistic analysis was conducted on the decision-making behavior of green manure planting based on the micro survey of 506 households.The results show that:From the perspective of farmers'' wishes,planting green manure to improve soil fertility and protect the environment can be supported by most farmers under the premise of fully respecting farmers'' pursuit of maximization of individual or family utility.From the mechanism of the influence of various factors,the age of farmers,whether they are village cadres,family income,the social and ecological welfare awareness and external factors are important factors influencing their decision-making behaviors.Compared with individual characteristics and family endowment,external factors have a more significant positive effect on farmers'' green manure planting decisions,especially policy publicity and planting subsidy.Based on the results above,the following policy implications are proposed:First,fully respect the wishes of farmers and guarantee their right to maximize their personal or family utility.Second,intensify policy publicity to raise farmers'' awareness of the comprehensive welfare of planting green manure.Third,integrate the resources of all parties and strengthen the construction of the green manure demonstration base.Finally,establish the ecological compensation mechanism of planting green manure and raise the subsidy standard.
