Research on the Mechanism Test and Spatial Optimization of Digital Economy driving the Improvement of New Quality Productivity in Hebei Province

Abstract

At the critical moment of industrial structure transformation and the kinetic energy conversion, the new digital economy as the core engine to foster productivity can assign role increasingly highlighted. As a major industrial province in northern China, Hebei province needs to solve the development dilemma of high proportion of traditional industries and insufficient innovation capacity. Based on the panel data of 11 cities in Hebei Province from 2011 to 2023, this paper constructs a comprehensive evaluation system of digital economy and new quality productivity, and uses entropy method, panel data model, mediating effect model and spatial Durbin model to systematically explore the enabling effect, mechanism, regional heterogeneity and spatial characteristics of digital economy on new quality productivity. Based on this, this paper puts forward countermeasures and suggestions from the four dimensions of digital infrastructure improvement, regional collaborative development, mechanism innovation activation and policy system optimization, providing decision-making reference for Hebei Province to solve the problems of industrial transformation and cultivate new quality productivity with the help of digital economy.
