摘要
农业产业链韧性是保障国家经济安全与稳定的重要基石,数实融合为破解其脆弱性提供了新路径。本研究基于2013—2022年中国30个省份的面板数据,构建中介效应与门槛效应双重检验框架,实证分析数实融合对农业产业链韧性的影响及作用机制。研究发现:第一,数实融合有效增强农业产业链韧性,且结论通过内生性与稳健性检验的严格验证;第二,科技创新是数实融合赋能农业产业链韧性的关键中介路径;第三,数实融合的驱动效应受区域异质性约束,人口密度与城镇化水平均呈现单一门槛特征,表现为跨门槛后边际效应递减;第四,高原山地地区因资源禀赋与政策适配性,其赋能效果更为显著。
The resilience of agricultural industrial chain is a critical foundation for guaranteeing national economic security and stability,with digital-real integration emerging as a novel pathway to address systemic vulnerability.Based on the panel data from 30 provinces in China from 2013 to 2022,this study constructed a dual-testing framework incorporating mediation and threshold effects to empirically analyse the impact mechanisms of digital-real integration on the resilience of agricultural industrial chain.Key findings reveal that:(1)Digital-real integration significantly enhances the resilience of agricultural industrial chain,and the conclusion is strictly verified by endogeneity and robustness tests;(2)Scientific and technological innovation is the key intermediary path for the resilience of agricultural industrial chain empowered by the digital-real integration;(3)The driver effects of the digital-real integration exhibit regional heterogeneity constrained by single-threshold characteristics in population density and the level of urbanisation,demonstrating diminishing marginal effects beyond threshold points;(4)The empowerment effects is more significant in the Mountainous regions due to resource endowment and policy alignment.
