摘要
农村地区数字基础设施对保障我国粮食安全发挥了重要作用。文章按照农村地区数字基础设施的用途将其划分为数字生产基础设施和数字生活基础设施,并从理论上阐述了数字生产基础设施对种植结构的影响机制以及数字生活基础设施在其中的调节效应,同时基于2011—2020年我国31个省份面板数据对上述关系进行了检验。研究结果表明:数字生产基础设施与种植结构存在“U”型曲线关系;数字生活基础设施在数字生产基础设施与种植结构两者关系中存在正向调节效应;数字生产基础设施与种植结构之间的“U”型关系在人力资本水平较高的地区表现显著,而在人力资本水平较低的地区表现不显著。根据研究结论,提出了充分发挥数字基础设施优势以促进种植结构“趋粮化”的政策建议。
Digital infrastructure in rural areas has played an important role in ensuring food security in China.According to the use of digital infrastructure in rural areas,this paper divides it into digital production infrastructure and digital living infrastructure,and theoretically expounds the impact mechanism of digital production infrastructure on planting structure and the moderating effect of digital living infrastructure in it;at the same time,this paper tests the above relationship based on the panel data of 31 provinces in China from 2011 to 2020.The research results indicate that there is a"U"curve relationship between digital production infrastructure and planting structure;the digital living infrastructure has a positive moderating effect on the relationship between digital production infrastructure and planting structure;the U-shaped relationship between digital production infrastructure and planting structure is significant in areas with high human capital levels,but not significant in areas with low human capital levels.Based on the research findings,policy recommendations are proposed to fully leverage the advantages of digital infrastructure to promote the"grain oriented"planting structure.
