数字经济驱动农业产业链现代化的实证检验

An Empirical Test of Modernization of Agricultural Industry Chain Driven by Digital Economy

数字经济深入发展可促进农业产业结构优化升级,为农业产业链现代化、数字化转型提供新动力。文章选取2012—2021年我国30个省份的面板数据,运用熵值法测度数字经济发展水平、农业产业结构优化水平及农业产业链现代化水平,检验数字经济对农业产业链现代化的影响效应;同时,将农业产业结构优化纳入中介效应模型,分析其在数字经济驱动农业产业链现代化过程中的传导作用。研究发现:数字经济发展有利于驱动农业产业链现代化,且该结论具有稳健性;数字经济可通过农业产业结构优化推动农业产业链现代化;异质性检验结果表明,低农业产业集聚地区数字经济对农业产业链现代化的促进效果更明显。

The in-depth development of digital economy can promote the optimization and upgrading of agricultural industri-al structure,and provide new driving force for the modernization of agricultural industrial chain and digital transformation.This paper selects the panel data of 30 provinces in China from 2012 to 2021,uses the entropy method to measure the digital economy development level,agricultural industrial structure optimization level and agricultural industrial chain modernization level,and tests the impact of digital economy on agricultural industrial chain modernization.At the same time,the optimization of agricultur-al industrial structure is introduced into the mediating effect model to analyze its conduction role in the process of modernization of the agricultural industrial chain driven by digital economy.The findings are shown as follows:The development of digital economy is conducive to driving the modernization of agricultural industry chain,and this conclusion remains robust.Digital economy can promote the modernization of agricultural industry chain through the optimization of agricultural industry structure.The heteroge-neity test results indicate that digital economy in low agricultural industry agglomeration areas has a more significant promoting ef-fect on the modernization of agricultural industry chain.
