摘  要：
近年来,中国政府对减少农药施用提出明确要求,然而除草剂作为三大类农药之一,其施用量却不断攀升,如何在确保产量的前提下,减少农户对除草剂的施用成为迫切需要解决的问题。本研究基于东北、华北大豆主产区的农户调查数据,通过构建链式中介效应,揭示大豆种植农户家庭禀赋和对转基因的认知程度如何影响农户的施药行为。结果显示,家庭人数对除草剂施用种类有显著负向影响,农户对转基因大豆的认知程度对除草剂施用种类有显著正向影响。同时,家庭人数通过农业收入间接影响除草剂施用种类,家庭人数通过"农业收入→除草剂成本"间接影响除草剂施用种类,对转基因的认知通过除草剂成本间接影响除草剂施用种类。

摘  要：
In recent years, the Chinese government has made clear requirements for reducing the application of pesticides. However, herbicide as one of the three major types of pesticides, its application amount has been increasing. Reducing the application of herbicides by farmers under the premise of ensuring yield has become an urgent problem to be solved. Based on the survey data of farmers in the main soybean producing areas of Northeast and North China, a chain mediating effect model was constructed to reveal the endowment of soybean farmers and the impact of their cognition of herbicide-tolerant genetically modified soybeans on herbicide use behavior. The results showed that the number of households had a significant negative impact on the types of herbicide application, and the cognition of genetically modified soybeans had a significant positive impact on the types of herbicide application. Moreover, the number of households indirectly affects the types of herbicide application through agricultural income, the number of households indirectly affects the types of herbicide application through "agricultural income → herbicide costs", and the awareness of genetic modification indirectly affects the types of herbicide application through herbicide costs.
