交通基础设施升级与农业生产效率提高
Upgrading Transportation Infrastructure and Enhancing Agricultural Production Efficiency:Empirical Evidence from 279 Cities with High-Speed Rail
摘要
Abstract
It is of great practical significance to scientifically evaluate the impact of upgrading transporta-tion infrastructure on agricultural productivity.The study finds that high-speed rail(HSR)opening ex-erts a positive effect on agricultural production efficiency.Specifically,the positive impact of HSR open-ing on pure technical efficiency outweighs its negative effect on scale efficiency,thereby enhancing overall agricultural comprehensive technical efficiency.The impact of HSR opening on agricultural production ef-ficiency exhibits notable regional heterogeneity.While HSR opening does not significantly affect agricul-tural production efficiency in cities located in the eastern region,it effectively improves such efficiency in cities in the central and western regions,yet suppresses efficiency improvement in cities in the northeast-ern region.Moreover,the efficiency-enhancing effect of HSR opening is more pronounced in areas char-acterized by higher industrial structure sophistication and higher urbanization levels.Both industrial struc-ture upgrading and urbanization intensify the positive effect of HSR opening on agricultural production effi-ciency.Importantly,these moderating effects operate primarily through improvements in pure technical ef-ficiency.Policy recommendations include:enhancing agricultural scale efficiency through scaled-up production;improving agricultural pure technical efficiency via transportation infrastructure upgrading;and leveraging the moderating roles of industrial structure upgrading and urbanization to further boost over-all agricultural technical efficiency.关键词
