Study on the influence mechanism of digital economy development on agricultural climate resilience — Based on the analysis of regulatory effects and spatial spillover effects

  • 摘要: 数字经济已成为重塑经济结构、重组生产资源、协调人与自然关系的核心要素。数字经济具有创新性强、覆盖面广、复制容易等优势, 能够迅速渗透到农业生产、经营、产业发展等各个领域。数字经济的快速发展为农业部门应对气候冲击提供了新的思路。本文基于2011—2020年我国30个省(自治区、直辖市, 不包括香港、澳门、台湾和西藏)的面板数据, 使用熵值法对数字经济发展水平和农业气候韧性进行测算, 分析了数字经济对农业气候韧性的影响, 并考察了财政支农和农业保险对该作用机制的调节效应。此外, 还通过构建空间计量模型探析了数字经济发展对农业气候韧性的空间溢出效应。结果表明: 我国农业气候韧性总体呈上升趋势, 但数值偏低, 仍存在较大的上升空间; 东部地区的农业气候韧性指数高于中部、西部以及东北部地区; 数字经济对农业气候韧性具有显著的促进作用, 且存在区域差异, 其中数字经济对东部地区农业气候韧性的促进作用最佳, 对中西部地区影响不显著, 对东北地区农业气候韧性具有抑制作用; 财政支农和农业保险强化了数字经济对农业气候韧性的影响; 数字经济对农业气候韧性的影响具有显著正向的空间溢出效应, 通过对动态空间杜宾模型进行分解发现短期效应要优于长期效应。本文为减缓和适应气候变化, 提升农业气候韧性提供了理论基础与政策依据。

     

    Abstract: The digital economy is a fundamental element in reshaping economic structures, optimizing resource allocation, and harmonizing the relationship between humans and nature. The digital economy has advantages such as strong innovation, wide coverage, and easy replication, and can quickly penetrate into various fields such as agricultural production, management, and industrial development. The rapid advancement of the digital economy has introduced new strategies for the agricultural sector to cope with climate shocks. This study utilized panel data from 30 provinces (autonomous regions and municipalities, not including Hong Kong, Macao, Taiwan and Xizang of China) in China from 2011 to 2020. Employing the entropy method, we measured the development levels of the digital economy and agricultural climate resilience. We then analyzed the impact of the digital economy on agricultural climate resilience and examine the regulatory effects of financial support for agriculture and agricultural insurance. Additionally, a spatial econometric model was constructed to explore the spatial spillover effects of digital economic development on agricultural climate resilience. The findings revealed that the overall agricultural climate resilience in China was increasing, albeit from a relatively low base, indicating significant room for improvement. The agricultural climate resilience index was highest in the eastern region, followed by the central, western, and northeastern regions. The digital economy significantly enhanced agricultural climate resilience, with notable regional differences. Specifically, the digital economy showed significant positive impact in the eastern region, no significant effect in the central and western regions, and significant negative impact in the northeastern region. Furthermore, financial support for agriculture and agricultural insurance amplified the positive effects of the digital economy on agricultural climate resilience. The influence of the digital economy on agricultural climate resilience exhibited a significant positive spatial spillover effect. We found that short-term effects surpass long-term effects via decomposing the dynamic spatial Durbin model. This study provides a theoretical and policy foundation for mitigating and adapting to climate change and enhancing agricultural climate resilience.
