信息素养、绿色防控技术采用行为对农户收入的影响

为帮助农户有效利用信息,顺应生态经济、绿色农业发展的趋势,持续稳定增收,本文基于山东寿光786户蔬菜种植户的调研数据,采用因子分析法,构建"认知、获取、分析、应用"4维农户信息素养测度指标体系,采用层次回归模型,实证检验信息素养、绿色防控技术采用行为对农户收入的影响及其路径,并采用工具变量法解决内生性问题。结果表明:1)信息素养正向显著影响绿色防控技术采用行为和农户收入;2)绿色防控技术采用行为在信息素养影响农户收入路径中具有部分中介效应,其中,是否采用和采用数量的中介效应占总效应的比重分别为73.09%和62.72%;3)蔬菜种植年限和是否参加技术培训正向显著影响绿色防控技术采用行为; 4)受教育年限、家庭规模、蔬菜种植年限和蔬菜收入占比正向显著影响农户收入,蔬菜销售市场距离负向显著影响农户收入。因此,信息素养不仅对农户收入具有直接影响,还通过绿色防控技术采用行为的中介效应对农户收入具有间接影响。据此,提出通过开展农户信息素养专题培训和加强绿色防控技术宣传推广力度等途径,以增加农户收入的政策建议。

The impact of information literacy and green prevention-control technology adoption behavior on farmer household income

Individual households are important to agricultural economic development and new rural construction. Household income directly affects the enthusiasm and creativity required for agricultural production and management. To help rural households stay up-to-date with new practices (including ecological farming), which may increase their income, this study created a four-dimensional measurement index system for information literacy from 786 vegetable-farming households in Shouguang, Shandong Province, China. An empirical test was performed to determine the impact of information literacy on green prevention-control technology adoption behavior and farmer household income using a hierarchical regression model and an instrumental variable method. Information literacy had significant positive effects on green prevention-control technology adoption behavior and farmer household income. Green prevention-control technology adoption behavior partially mediated the influence path of information literacy to farmer household income. The mediating effect of adopting (or not) green prevention-control technology was accounted for 73.09%, and the number of green prevention-control technologies adopted was accounted for 62.72%. The years of cultivation experience and the decision to attend technical training had significant positive effects on green prevention-control technology adoption behavior. Farmer household income was significantly positively affected by the years of education, household size, the years of cultivation experience and the proportion of income from vegetable farming, but farmer household income was significantly negatively affected by distances to the vegetable market. Information literacy had a direct impact on household income, but also indirectly influenced income by the mediating effect of green prevention-control technology adoption behavior. Therefore, policy changes to increase household income through information literacy training and promoting green prevention-control technologies may be beneficial. This study established an analysis framework to explore the effects of information literacy and green prevention-control technology adoption behavior on farmer household income. A measurement index system for household information literacy was created to measure aggregate levels, and a characteristic index of green prevention-control technology adoption behavior was optimized, providing guidance and insight into the increase of farmer household income.
