An Empirical Study on the Impact of Digital Economy Development on Industrial Structure Optimization in Northeast China

The clarification of how to use digital technology to accelerate the optimization of industrial structure in Northeast China will provide theoretical support for the policy proposals for the comprehensive revitalization of Northeast China and has certain reference value for other Chinese provinces and regions as well. In this article, entropy method, system GMM dynamic panel model and Robust regression model were used to quantitatively measure the panel data of the three Northeast provinces from 2013 to 2022 around the comprehensive level of digital economy development and its impact on industrial structure optimization, as well as the sub-dimensional test and spatial heterogeneity test. The results show that the driving force of digital economy has not yet been fully released, which cannot effectively promote the rationalization and upgrading of the industrial structure. To this end, the three Northeastern provinces should establish a learning mechanism, coordinate development, implement differentiated strategies, improve personnel training and development, accelerate the cultivation of digital emerging industries and the penetration and integration of industrial digitalization.
