| 摘要: |
| 为分析社会网络与农户化肥过量施用行为之间的关系，利用东北三省741户玉米种植农户的实地调研数据，构建“社会网络—环境素养—化肥过量施用”的理论分析框架，运用bootstrap多重中介效应检验方法考察环境素养的中介作用，探究社会网络抑制农户过量施用化肥行为的作用机制。结果表明:1)社会网络对农户化肥过量施用行为的影响包括直接负向影响和通过环境素养产生的间接负向影响。2)社会网络对环境知识、环境技能、环境认知、环境态度均具有显著的正向影响，但只有环境技能、环境认知和环境态度能显著抑制农户化肥过量施用行为。3)社会网络能够通过提高环境技能、增强环境认知以及改变环境态度来抑制农户化肥过量施用行为。环境技能的中介抑制效应最强，而环境知识的中介抑制效应不显著。因此，加强农村社会网络建设、转变农业技术培训的内容与形式、加大农业生态保护的宣传力度，对增强农户的化学品减量意识、促进农业高质量发展具有重要意义。 |

| Abstract: |
| In order to analyze the relationship between social network and farmers' excessive application of chemical fertilizer, the field survey data of 741 corn farmers of the three provinces in Northeast China is used, and theoretical analysis framework between social network, environmental literacy and excessive application of chemical fertilizer is built. Bootstrap multiple mediating effect test method is adopted to investigate the mediating effect of environmental literacy and explore the mechanism of social network inhibiting farmers' excessive application of chemical fertilizer. The results show that: 1)The impact of social network on farmers' excessive application of chemical fertilizer includes direct negative impact and indirect negative impact through environmental literacy. 2)Social network has a significant positive impact on environmental knowledge, environmental skills, environmental cognition and environmental attitude, but only environmental skills, environmental cognition and environmental attitude can significantly inhibit farmers' excessive application of chemical fertilizer. 3)Social network can restrain farmers' excessive application of chemical fertilizer by improving environmental skills, enhancing environmental awareness and changing environmental attitudes. The mediating inhibitory effect of environmental skills is the strongest, while the mediating inhibitory effect of environmental knowledge is not significant. Therefore, strengthening the construction of rural social network, changing the content and form of agricultural technology training, and increasing the publicity of agricultural ecological protection are of great significance to enhance farmers' awareness of chemical reduction and promote the high-quality development of agriculture. |
