数字经济与科技创新的协同效应对新质生产力发展的空间影响研究

The Synergistic Effect of Digital Economy and Technological Innovation on New Quality Productivity

摘要: 在我国由传统生产力向新质生产力转型过程中，数字经济与科技创新已成为关键驱动力。本文基于2012~2024年省级面板数据，从耦合协调视角分析二者协同作用对新质生产力的影响机制。通过构建指标体系并测算耦合协调度，结合基准回归、中介效应与空间模型进行实证检验。结果表明：协同效应显著促进新质生产力发展，且优于单一因素；数字普惠金融发挥重要传导作用；新质生产力及其协同效应存在空间相关性，科研要素流动具有正向溢出效应。

Abstract: During China’s transition from traditional productivity to new quality productive forces, the digital economy and technological innovation have become key driving forces. Based on panel data of provincial-level units from 2012 to 2024, this study analyzes the impact mechanism of their synergistic effects on new quality productive forces from the perspective of coupling coordination. By constructing an evaluation index system and measuring the coupling coordination degree, and employing baseline regression, mediation analysis, and spatial econometric models, the results show that: the synergistic effect significantly promotes the development of new quality productive forces and performs better than single-factor effects; digital inclusive finance plays an important mediating role; and both new quality productive forces and their synergistic effects exhibit significant spatial correlation, with the flow of scientific research factors generating positive spillover effects.
