| 为厘清农业数字化对粮食生产安全的影响效应，基于粮食主产区13个省份2011—2021年的省级面板数据，采用熵权法构建了农业数字化和粮食生产安全的评价指标体系，并建立面板数据基准回归模型和门槛效应模型，实证分析了农业数字化对粮食生产安全产生的影响。实证结果表明：1）农业数字化的发展对保障粮食生产安全有显著的正向效应，但其影响效用只有农业数字化水平发展到一定程度才能充分显现；2）当农业数字化处于较低水平时，对粮食生产具有一定的负向效应；当农业数字化水平提升至较高水平时，对粮食生产安全的影响会转变为正向促进作用；3）进一步研究发现，农业数字化建设对粮食生产安全的影响存在地区差异，农业数字化对华北平原及长江中下游平原地区的粮食生产安全产生了显著的正向效应，而对东北平原粮食生产安全未产生显著影响。因此，我国应充分把握农业数字化发展机遇，推动农业数字化基础设施建设，为粮食生产安全提供有力保障；因地制宜采用不同的农业数字化推进策略，以有效保障区域粮食生产安全；搭建区域协作机制，共享农业数字化发展经验。 |

| Abstract: |
| In order to clarify the effect of agricultural digitization on food production security， based on a provincial panel data of 13 provinces （2011-2021） in major grain-producing areas， an evaluation index system of agricultural digitalization and food production security was constructed using entropy weight method. The baseline regression model and threshold effect model of panel data were established to empirically analyze the impact of agricultural digitalization on food production security. The empirical results show that： 1） The development of agricultural digitalization has a significant positive effect on ensuring food production security， but its effect can only be fully manifested when the level of agricultural digitalization is developed to a certain extent. 2） When agricultural digitization is at a low level， it has a certain negative effect on food production. When the level of agricultural digitization is elevated to a higher level， the impact on food production security will turn into a positive promotion. 3） Further research shows that the impact of agricultural digitalization on food production security is different in different regions. Agricultural digitalization has a significant positive effect on food production security in the North China Plain and the middle and lower reaches of the Yangtze River Plain， but has no significant impact on the Northeast Plain. Therefore， this study put forward three proposals as follows： Grasping the opportunity of agricultural digital development， promote the construction of agricultural digital infrastructure， and provide a strong guarantee for food production security in China； Adopting different agricultural digital promotion strategies according to local conditions to effectively ensure regional food production security； Establishing regional cooperation mechanisms to share experience in agricultural digital development. |
