数字化转型对长江经济带农业高质量发展的影响研究

Research on the Impact of Digital Transformation on the High Quality Development of Agriculture in the Yangtze River Economic Belt

基于2011—2021年长江经济带11个省(市)面板数据,采用熵值法构建了数字化转型与农业高质量发展评价指标体系,运用双向固定效应模型实证检验数字化转型对长江经济带农业高质量发展的影响和区域异质性及指标异质性。结果表明:数字化转型能够驱动长江经济带农业高质量发展,这一结论通过了稳健性检验;数字化转型对长江经济带不同区域农业高质量发展的影响具有异质性。其中对下游地区的农业高质量发展的促进作用最强,中游次之,对上游地区则较弱。经过指标异质性检验后发现,数字化转型对长江经济带农业高质量发展的共享的促进作用最强,创新、协调和绿色次之,对开放的影响不显著。据此,提出夯实数字化技术基础工程,培养农业数字化运用人才,加强数字区域协调发展,促进农业高质量发展的对策建议。

Based on panel data from 11 provinces(cities)in the Yangtze River Economic Belt from 2011 to 2021,an evaluation index system for digital transformation and high-quality agricultural development was constructed using the entropy method.A bidirectional fixed effect model was used to empirically test the impact of digital transformation on high-quality agricultural development in the Yangtze River Economic Belt,as well as regional heterogeneity and indicator heterogeneity.The research results indicate that digital transformation can drive the high-quality development of agriculture in the Yangtze River Economic Belt,which has passed the robustness test;the impact of digital transformation on the high-quality development of agriculture in different regions of the Yangtze River Economic Belt is heterogeneous.The promotion of high-quality agricultural development in downstream areas is the strongest,followed by the middle reaches,and weaker in upstream areas.After testing the heterogeneity of indicators,it was found that digital transformation has the strongest promoting effect on the sharing of high-quality agricultural development in the Yangtze River Economic Belt,followed by innovation,coordination,and green,and has no significant impact on openness.Based on this,countermeasures and suggestions are proposed to strengthen the foundation engineering of digital technology,cultivate talents for agricultural digital application,strengthen the coordinated development of digital regions,and promote high-quality agricultural development.
