农业数字化对粮食生产安全的影响机理与效应
Influence mechanism and effect of agricultural digitization on food production security
摘要
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.关键词
