摘要:

目的 探究数字普惠金融对粮食体系韧性的影响，为保障国家粮食安全，实现农业农村现代化指明新的方向。方法 文章基于2011—2020年全国31个省（市、区，不含港澳台地区）的面板数据，从抵抗能力、适应能力、变革能力3个维度出发构建粮食体系韧性综合评价指标体系，运用熵值法测算粮食体系韧性水平，利用空间计量模型实证检验数字普惠金融对粮食体系韧性的空间溢出效应和异质性。结果 数字普惠金融对粮食体系韧性具有显著的正向空间溢出效应，即数字普惠金融能够提升当地及邻近地区的粮食体系韧性；数字普惠金融的覆盖广度、使用深度和数字化程度均有助于粮食体系韧性的提升；不同区域的数字普惠金融对粮食体系韧性的影响差异显著，其中主销区数字普惠金融对粮食体系韧性的提升作用最大，主产区和产销平衡区次之。结论 应大力发展数字普惠金融，推动农村数字普惠金融基础设施建设，提高农户金融素养，创新金融服务模式和数字技术，因地制宜发挥各产区优势，并加强地区间的相互合作。

Abstract:

To explore the impact of digital inclusive finance on the resilience of the food system to point out new direction for guaranteeing national food security and realizing agricultural and rural modernization. Based on the panel data of 31 provinces nationwide from 2011 to 2020, this research constructed a comprehensive evaluation index system of food system resilience from three dimensions of resistance, adaptability and change ability, measured the level of food system resilience by using the entropy value method, and empirically tested the spatial spillover effect and heterogeneity of digital inclusive finance on food system resilience by using a spatial econometric model. It was found that digital inclusive finance had a significant positive spatial spillover effect on food system resilience, i.e., digital inclusive finance could enhance the food system resilience in the region and neighboring regions; the breadth of coverage, depth of use and digitalization of digital inclusive finance all contributed to the improvement of food system resilience; the impact of digital inclusive finance on food system resilience varied significantly across regions, with the main marketing areas having the largest effect of digital inclusive finance on food system resilience, followed by the main production areas and balanced production and marketing areas. Therefore, it should vigorously develop digital inclusive finance, promote the construction of rural digital inclusive financial infrastructure, improve the financial literacy of farmers, innovate financial service models and digital technologies, give full play to the advantages of each production area according to local conditions, and strengthen mutual cooperation among regions.
