The Mechanism and Effect of the Promotion of Industrial Structure Upgrading by Digital Economy

The upgrading of industrial structure is the internal driving force and the important premise to promote the high-quality development of China's economy, and the digital economy is the catalyst for the upgrading of industrial structure and the high-quality development of China's economy. At present, China is in a critical period of industrial structural transformation and upgrading and the transformation of economic structure, and the digital economy has become an important driver in promoting high-quality economic development. In this context, clarifying the relationship between digital economy and industrial structure upgrading will help promote the upgrading of China's industrial structure and effectively achieve high-quality economic development.#br#However from the perspective of research objects, scholars either only focus on the analysis of the impact of digital industrialization on industrial structure upgrading, or only focus on the impact of industrial digitalization, ignoring the joint impact of digital economy (including digital industrialization and industrial digitalization); from the perspective of research methods, there is a linear and nonlinear relation between digital industrialization, industrial digitalization, digital economy and industrial structure upgrading, but scholars are only limited to linear research, and lack of nonlinear relation research between them. Then what is the mechanism of digital industrialization, industrial digitization and digital economy to promote industrial structure upgrading? Which effect is bigger,digital industrialization or industry digitization?#br#This paper analyzes the mechanism of digital industrialization, industrial digitization and digital economy promoting industrial structure upgrading. (1) Digital industrialization promotes the upgrading of industrial structure. From the time dimension, digital industrialization improves the efficiency of each stage of the industrial chain (design, production and commercialization) through matching and intelligent effect, and promotes the advanced industrial structure. From the spatial dimension, digital industrialization promotes new industries through the derivative effect, and realizes the rationalization of industrial structure. (2) Industrial digitalization promotes the upgrading of industrial structure. From the time dimension, industrial digitalization improves the efficiency of each stage of the industrial chain through the effect of penetration and integration, and promotes the upgrading of industrial structure. From the spatial dimension, industrial digitization optimizes resource allocation and promotes the rationalization of industrial structure through driving and correlation effects. (3)The digital economy promotes the upgrading of industrial structure and industrial structure upgrading through superposition and multiplication effect. This paper builds a threshold effect model, and collects relevant data on digital economy and industrial structure upgrading in 30 provinces and municipalities from 2011 to 2020.By accurate measurement of the effect of digital industrialization, industrial digitization and digital economy, it analyzes the relation between digital industrialization and industrialization in various regions, and makes a visual analysis of the synergy of the industrial digitalization level.#br#It is concluded that digital industrialization has an inverted u-shaped increasing effect on the upgrading of industrial structure; industrial digitization has a positive and increasing effect on it; digital industrialization has a greater promoting effect on the upgrading of industrial structure; digital economy has a positive and increasing effect on the upgrading of industrial structure; there are four types of the synergy level of digital industrialization and industrial digitization:the double high type of digital industrialization and industrial digitalization,the double low type of digital industrialization and industrial digitalization,the enhanced type of digital industrialization and industrial digitalization and the enhanced type of digital industrialization and industrial digitalization.#br#Given the above conclusions, it is firstly suggested to increase investment in research and development to promote innovation in digital technology, accelerate the transformation of digital technology achievements from research and development to finished products and cultivate a new generation of digital industrial clusters. Secondly it is necessary to strengthen industrial digitalization to empower innovation and fully release digital dividends. Thirdly it is important to focus on common digital technology research and build digital industry clusters. Fourthly it is vital to coordinate the development layout of the regional digital economy, and continue to promote the coordinated development of digital industrialization and industrial digitalization. Lastly governments should implement policies in different regions and develop according to local conditions. For example, the double-high eastern region needs to continue to maintain a high level of digital economy; the double-low central and western regions need to further improve the level of industrial digitization and digital industrialization.#br#
