数字经济赋能农业高质量发展研究--基于湖南省2012—2020年面板数据的分析

Research on digital economy enabling high-quality agricultural development:Based on the analysis of panel data of Hunan province from 2012 to 2020

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, βconvergence 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.
