粮食科技与经济

深入探讨数字经济对粮食生产韧性的影响，对实现粮食产业高质量发展和保障国家粮食安全意义重大。利用2012—2021年30个省份的面板数据，实证分析了数字经济对粮食生产韧性的影响效应及作用机制。研究发现，2012—2021年，粮食生产韧性总体水平呈现出上升趋势，但各省份粮食生产韧性水平差异明显。数字经济对粮食生产韧性具有促进作用，其中数字经济环境对粮食生产韧性的影响程度最大。新型农业经营主体成立和农地流转是数字经济影响粮食生产韧性的重要机制。数字经济对粮食主产区和产销平衡区的粮食生产韧性具有促进作用，对粮食主销区的粮食生产韧性具有抑制作用；数字经济对粮食生产韧性的作用程度在中部地区最强，西部地区次之，东部地区最弱。最后，为提高粮食生产韧性和保障中国粮食安全，提出了完善数字经济基础设施建设，提升农业经营主体的数字素养，因地制宜发挥各产区优势等政策建议。

Investigating the impact of digital economy on the resilience of grain production holds significant strategic importance for ensuring national food security and achieving high-quality development in the grain industry. This paper uses panel data from 30 provinces from 2012 to 2021 to empirically analyze the impact effect and mechanism of digital economy on the resilience of grain production. The findings reveal that the overall resilience of grain production showed an upward trend from 2012 to 2021, but regional disparities among provinces remain significant. Digital economy significantly enhances grain production resilience, with digital economy environment exerting the strongest influence. Key mechanisms include alleviating fostering the establishment of new agricultural business entities and facilitating farmland transfer. The digital economy has a promoting effect on the resilience of grain production in major grain-producing areas and grain production-consumption balanced areas, while it has an inhibitory effect on the resilience of grain production in major grain-consuming areas. The impact of the digital economy on the resilience of grain production is the strongest in the central region, followed by the western region, and the weakest in the eastern region. Finally, in order to improve the resilience of grain production and ensure China's food security, this paper puts forward policy suggestions such as improving the construction of digital economy infrastructure, enhancing the digital literacy of agricultural operators, and giving full play to the advantages of various producing areas in light of local conditions.
