摘要
文中以典型黑土区1017户农户微观调查数据为基础,运用倾向得分匹配法从信息利用角度考察互联网使用对农户黑土地保护行为的影响效应,并在此基础上探索群体间的影响差异。研究结果显示:1)样本区有33.04%的农户通过互联网获取耕地保护信息。2)在考虑反事实情况的基础上,使用互联网获取耕地保护信息的农户参与黑土地保护的概率比与不使用互联网获取相关信息的农户高32.31%。使用工具变量法检验内生性问题后,实证结果依然稳健。进一步分析表明,互联网使用对黑土地保护行为的影响在不同代际、不同受教育程度和农业依赖程度间存在差异。3)互联网使用主要通过提升危机意识、拓宽信息获取渠道、增强社会互动三种渠道影响农户黑土地保护行为。
Based on the micro survey data of 1017 households in typical black soil area,we used the propensity score matching method to investigate the impact of Internet use on farmers'black soil protection behavior from the perspective of information utilization,and further to explore the impact differences among groups.The results of the study show:1)In the sample area,33.04% of the farmers obtained the cultivated land protection information through the Internet.2)Considering the counterfactual situation,the probability of farmers who used the Internet to obtain farmland protection information to participate in black earth protection was 32.31% higher than that of farmers who did not use the Internet to obtain relevant information.Using the instrumental variable method to test endogenous problems,the empirical results were still robust.Further analysis showed that the influence of Internet use on black soil protection behavior varied among different generations,different levels of education and agricultural dependence.3)The use of the Internet mainly affects farmers'black soil protection behaviors through three channels:raising crisis awareness,broadening information acquisition channels,and enhancing social interaction.
