摘要:
本文基于2013—2023年我国29个省(自治区、直辖市)的面板数据,构建双固定效应模型,实证研究数字经济对农民收入的影响。结果表明,数字经济发展促进农民增收,但地区异质性显著,西部和中部地区的影响效应显著为正,东部地区由于数字经济发展快但未能及时提升农民技能以适应新的经济环境,增收效应未能体现。数字经济在不同维度的影响差异显著,其中数字经济基础设施水平的影响不显著,数字经济应用水平和数字经济环境水平的影响均显著,且数字经济环境水平的促进作用最强。在4个控制变量中,城镇化水平对农民收入增长的影响最大,地区经济发展水平和农村人力资本也都显著促进了农民收入的增长。建议深入实施数字乡村建设行动,加大人才培养力度,完善配套政策,推动数字经济与农村经济深度融合。
