基于SEM的农户施肥行为及其影响因素实证研究

农户是农业生产中生产要素的主要投资者,是施用化肥的主体,因此关注农户的施肥行为及其影响因素,对保护农业生态环境有很重要的意义。基于河南省驻马店地区的281份有效问卷,采用结构方程模型(SEM)探讨影响农户施肥行为的主要因素。结果表明:过量施用化肥的认识、有机肥施用效果认知和提高施肥技能对农家肥施用行为的影响是显著正向的,标准化路径系数分别为0.194 6、0.634、0.486,对商品有机肥施用行为的影响是显著正向的,标准化路径系数分别为0.102 8、0.335、0.568,而对化肥合理施用行为的影响不显著,标准化路径系数分别为0.142 6、-0.024、0.194,了解化肥信息对化肥合理施用行为的影响是不显著的,标准化路径系数为0.087。在此基础上提出建议:加强农户对化肥过量危害的负面认识,农户对有机肥施用效果的认知程度,完善农家肥补贴措施和重视施肥技术培训工作。

The empirical research of farmer's fertilization behavior and its influencing factors based on the structural equation model

Famers are the main investors during agriculture production,they are the main body of using the chemical fertilizers,so paying more attention to famer's fertilization behavior and its influencing factors has very important significance to protect the agricultural ecological environment.Based on 281 valid questionnaires in Zhumadian region of Henan province,this study adopted structural equation model (SEM) to investigate the influence on farmer's fertilization behavior,the result showed the awareness of the excessive use of chemical fertilizers,the awareness of organic fertilizer's effect,congnition of effect of using organic fertilizer,and human capital promotion had positive significant influence on farmer's manure application behavior,the standardized regression weights were 0.194 6,0.634,0.486 respectively,these factors also had positive significant influence on farmer's commercial organic fertilizer application behavior,the standardized regression weights were 0.102 8,0.335,0.568 respectively,but they had insignificant influence on farmer's rational use of chemical fertilizer,the standardized regression weights were 0.142 6,-0.024,0.194 respectively.Acguaint fertilizer information had positive insignificant on farmer's rational chemical fertilizer application,the standardized regression weight was 0.087.In the end some suggestions like strengthening education naying more attention to farmer's training,improving the effect of organic fertilizer application of farmer's cognition and the farmyard manure subsidy policy were put forward.
