摘要
促进水稻—冬闲农作系统向绿肥稻作系统转型是强化区域耕地质量保护与提升、保障国家粮食安全的有效措施。基于南方稻作区安徽、湖南、广西三省区934份农户调查数据,采用PLS-SEM模型和Bootstrap检验方法,分析知识扩散对农户绿肥稻作系统采纳意愿的影响效果与作用路径,并进一步运用Ordered logit模型揭示异质性农户禀赋对其参与农业知识扩散活动的影响。结果表明:知识扩散对农户绿肥稻作系统采纳意愿具有显著正向的直接影响;外部风险感知与组织信任、生态服务价值感知与组织信任分别在知识扩散对农户绿肥稻作系统采纳意愿的影响中存在链式中介作用;知识扩散通过农户障碍感知对农户绿肥稻作系统采纳意愿产生显著的间接作用;参加合作社、务农经验、教育程度、家庭收入、身体健康状况均对农户参加知识扩散活动具有显著的正向影响。据此,本研究提出开展系统性宣讲培训活动、提高农户组织信任、改善农户禀赋条件等政策建议。
Promoting the transformation of rice planting from rice-winter idle farming system to green manure-rice system is an effective way to strengthen the protection and improvement of regional cultivated land quality and guarantee national food security.Based on the survey data of 934 farmers in Anhui,Hunan and Guangxi,the PLS-SEM model and Bootstrap test method were used to analyze the effect and path of knowledge diffusion on farmers’intention to adopt green manure-rice system.Furthermore,the Ordered Logit model was used to reveal the influence of heterogeneous farmers’endowment on their participation in agricultural knowledge diffusion.The results showed that:1)Knowledge diffusion had a significant positive direct effect on farmers’intention to adopt green manure-rice cropping system.2)External risk perception and organizational trust,ecological service value perception and organizational trust had a chain mediating effect on the influence of knowledge diffusion on farmers’intention.3)Knowledge diffusion had a significant indirect effect on farmers’intention through their perception of obstacles.4)Participation in cooperatives,farming experience,education level,family income and health status had significant positive effects on farmers’participation in knowledge diffusion activities.Therefore,some counter measures such as carrying out systematic propaganda and training activities,enhancing the trust of farmers’organizations and improving the conditions of farmers’endowment,were put forward.
