基于湖南省14个市（州）2012—2020年的面板数据，运用固定效应模型、β收敛检验和面板门限模型，探析数字经济赋能农业高质量发展的内在逻辑。结果表明：首先，数字经济整体上能够促进农业高质量发展，并显著提高农业发展水平，推进产业成果共享，优化农业生态环境以及提升农业经济效益；其次，农业高质量发展存在一定程度的收敛性，即落后地区发展水平增速高于发达地区，区域间农业高质量发展水平差距逐渐缩小；最后，数字经济存在一定的空间聚集特征，这种特征会导致其在农业应用上产生“数字鸿沟”，主要表现为对发达地区的农业高质量发展促进作用强，对落后地区的促进作用弱，不利于农业高质量发展实现区域均衡发展。

Based on the panel data of 14 cities (prefectures) in Hunan province from 2012 to 2020, the internal logic of digital economy empowering high-quality agricultural development has been explored by using the fixed effect model, β convergence test and panel threshold model. The result shows that firstly, the digital economy could boost the high-quality development of agriculture as a whole, significantly improve the level of agricultural development, promote the sharing of industrial achievements, optimize the agricultural ecological environment and improve the economic benefits of agriculture. Secondly, there is a certain degree of convergence in the high-quality development of agriculture, that is, the growth rate of the development level of backward areas is faster than that of developed areas, and the gap in the level of high-quality agricultural development between different regions is gradually narrowing. Finally, the digital economy has a characteristic of certain spatial aggregation. This characteristic would lead to a “digital divide” in agricultural applications, which is mainly manifested in that it has a strong promotion effect on the high-quality agricultural development in developed areas, but a weak promotion effect on backward areas, which is not conducive to the high-quality development of agriculture to achieve balanced development of regions.
