Empirical Analysis of Digital Economy Affecting Industrial Chain Modernisation Based on Panel Regression Model and Threshold Effect Model

This study employs panel data from 2015-2020 to construct a panel regression model as well as a threshold effect model in order to examine the impact of the burgeoning digital economy on the modernization of the industrial chain in China.The results of the study show that the modernisation of the chain is positively influenced by the digital economy, with a nonlinear increasing trend.However, Once the development of the digital economy reaches a threshold, its catalytic effect on the modernization of the industrial chain slightly decreases.This research provides new insights for the exploration of China's industrial chain modernization and offers a solid theoretical foundation and empirical support for studying the impact of the digital economy on the modernization of the industrial chain.
