The Impact of the Digital Economy on the Optimization of Industrial Structure: An Empirical Study Based on the Intermediary Role of Technological Innovation

Abstract

The digital economy has become an important path for the transformation and upgrading of industrial structure. Technological innovation, as the primary driving force for development, is a key entry point in analyzing this issue. This paper conducts empirical analysis based on Panel data of 31 provinces in China from 2011-2021, and constructs Mesomeric effect and moderating effect models. Research has found that the development of the digital economy has a significant promoting effect on the rationalization of industrial structure; The digital economy can promote the improvement of technological innovation level; From a national perspective, the level of technological innovation reflects the masking effect in the process of promoting industrial structure rationalization in the digital economy, and this conclusion is still valid after robustness testing.Based on this, we need to strengthen the construction of digital infrastructure, rely on the digital economy to stimulate independent innovation and technological transformation level, and promote the upgrading of industrial structure.
