国家数字乡村试点政策能否促进农业产业链和创新链融合发展？

Can the national digital rural pilot policy promote the integrated development of the agricultural industry chain and innovation chain?

摘要:

植根于新发展阶段国情农情,国家数字乡村试点政策以解放和发展数字化生产力为指向,成为促进农业产业链和创新链融合发展的核心动能。设立国家数字乡村试点政策准自然实验,依托2016-2024年766个县(县级市、区)的面板数据,借助多期双重差分模型与中介效应模型识别国家数字乡村试点政策对农业产业链和创新链融合发展的影响效应及中介效应。实证结果表明:国家数字乡村试点政策可正向促进农业产业链和创新链融合发展,且该结果经由系列稳健性检验之后证实具有稳健性。中介效应检验发现,数据要素配置、耐心资本投入是国家数字乡村试点政策促进农业产业链和创新链融合发展的中介变量。异质性检验发现,相比高海拔与劳动力规模较小的地区,国家数字乡村试点政策对低海拔、劳动力规模较大地区的农业产业链和创新链融合发展促进作用更强。研究结论可为稳步推动农业产业链和创新链融合发展提供实践参考。

Abstract:

Rooted in the national conditions and agricultural conditions of the new development stage, the national digital rural pilot policy aims to liberate and develop digital productivity, becoming the core driving force for promoting the integrated development of the agricultural industry chain and innovation chain. Establish a quasi natural experiment for the national digital rural pilot policy, relying on panel data from 766 counties (county-level cities, districts) from 2016 to 2024, using a multi period difference in differences model and mediation effect model to identify the impact and mediation effects of the national digital rural pilot policy on the integrated development of the agricultural industry chain and innovation chain. The empirical results indicate that the national digital rural pilot policy can positively promote the integrated development of the agricultural industry chain and innovation chain, and this result has been confirmed to be robust after a series of robustness tests. The mediation effect test found that data element allocation and patient capital investment are mediating variables for the national digital rural pilot policy to promote the integrated development of the agricultural industry chain and innovation chain. Heterogeneity testing found that compared to high-altitude and smaller labor force areas, the national digital rural pilot policy has a stronger promoting effect on the integrated development of agricultural industry chain and innovation chain in low altitude and larger labor force areas. The research conclusion can provide practical reference for steadily promoting the integrated development of agricultural industry chain and innovation chain.
