摘要/Abstract

摘要： 作为当前我国稻作地区农户广泛采纳的生态农业模式之一，水稻-小龙虾（稻虾）共作模式中农户农资投入减量化行为及其影响因素的研究对农田资源高效利用和农业可持续发展具有重要意义。以江苏省3市589个采用稻虾共作模式的农户为样本，基于农户行为选择理论和结构方程模型，分析稻虾共作模式中农户农资（化肥、农药和饲料）投入减量化行为及其关键影响因素。结果表明，在稻虾共作模式中，大部分农户倾向于减少化肥、农药和饲料的投入；农户对稻虾共作模式的认知和外部环境对农户农资投入减量化行为有显著正向影响，且对稻虾共作模式认知的影响程度大于外部环境；农户对稻虾共作模式能否减少农资投入的认知、对过量农资投入会污染环境的认知、农技部门指导、农业保险、农业补贴及邻里效应等因素对农户农资投入减量化行为均有显著影响。最后提出应提高农户的综合资本禀赋、加强农技部门指导和培训、完善扶持政策和奖惩机制、做大做强稻虾公用品牌等政策建议。

Abstract: The rice and crayfish co-cropping mode is one of the existing ecological agriculture modes widely adopted by the farmers in paddy fields of China. Therefore, clarification of the agricultural input reduction behavior and its influencing factors in this mode has an important effect on the efficient utilization of farmland resources and agricultural sustainable development. By taking 589 rice and crayfish co-cropping farmers from 3 cities in Jiangsu Province as the samples, the agricultural input (including fertilizers, pesticides, and feed) behavior and its main influencing factors in the rice and crayfish co-cropping mode were analyzed based on the farmers' behavioral selection theory and the structural equation model. The results show that most of farmers tend to reduce the input of fertilizers, pesticides and feed in the rice and crayfish co-cropping mode. The farmers' cognition to rice and crayfish co-cropping mode and the external environment have significant positive effects on the agricultural input reduction behavior, and the influence of the former is greater than that of the latter. In addition, the influence factors, including the farmers' cognition that the rice and crayfish co-cropping mode enables the agricultural input reduction, and excessive agricultural input will lead to environmental pollution, the guidance given by the agricultural technology department, agricultural insurance, agricultural subsidies and neighborhood effect all could significantly impact the agricultural input reduction behavior. Accordingly, it is proposed that comprehensive capital endowment of farmers might be improved, the agricultural technology department should increase the efforts to give guidance and strengthen the effect, the support policies and rewards and punishment mechanisms should be improved, and the brand of rice and crayfish should be established.

Key words: rice and crayfish co-cropping, farmers, agricultural input reduction, behavioral selection theory, structural equation model
