摘要
本文基于2021年中国土地经济调查数据实证分析互联网使用对种植结构调整的影响时发现:第一,互联网使用可以显著降低农户的种粮比例,造成种植结构“非粮化”问题,选取工具变量进行两阶段最小二乘法估计解决内生性问题后上述结论依然成立,使用替代自变量法进行稳健性检验后结果依然稳健。第二,对户主性别分组进行异质性分析发现不同户主性别条件下互联网使用对种植结构的影响程度不同。第三,互联网使用可以通过提高农户金融信贷可得性和降低经济作物成本降低种粮比例,使种植结构产生“非粮化”调整。根据研究结果提出,需牢牢守住保障粮食安全的底线,关注不同类型家庭的农业生产活动,建立促使种植结构“趋粮化”的多元路径等对策建议。
An empirical analysis based on China's 2021 Land Economic Survey data,examining the impact of internet use on planting structure adjustments,revealed the following:First,internet use can significantly reduce the proportion of grain cultivation by farmers,leading to a“de-grainization”of the planting structure.This conclusion remained valid after addressing endogeneity issues using instrumental variables in a two-stage least squares estimation.The results remained robust after conducting sensitivity tests using alternative independent variables.Second,heterogeneity analysis by grouping household heads by gender showed that the impact of internet use on planting structure varied under different household head gender conditions.Third,internet use can reduce the proportion of grain cultivation and cause a“de-grainization”adjustment in the planting structure by improving farmers’access to financial credit availability and reducing the costs of economic crops.According to the research results,it is necessary to firmly hold the bottom line of ensuring food security,pay attention to agricultural production activities of different types of households,and establish multiple paths to promote the“grain-oriented”planting structure.
