创新活力、数字基建与地区经济增长的路径

The Path of Innovation Vitality, Digital Infrastructure and Regional Economic Growth

摘要: 在数字经济成为全球经济增长核心动力的背景下，数字基建与创新活力已成为影响地区经济发展的关键要素。本文基于2005~2023年省级面板数据，构建多元线性回归与面板数据模型，实证检验三者的关联机制与异质性特征。研究表明，数字基建通过优化资源配置、赋能产业升级、扩大市场规模直接驱动经济增长，创新活力则以技术、模式、制度创新为核心赋能经济发展，且二者存在相互促进的协同效应。异质性分析显示，低人均GDP地区与西部地区对数字基建的经济响应更显著，东部地区则呈现数字基建与创新活力双轮驱动格局。在此基础上，本文从优化区域基建布局、构建差异化创新生态、强化二者协同、完善区域协调政策四个维度，提出推动三者深度融合的实践路径，为各地依托数字经济实现高质量发展提供理论参考与实践启示。

Abstract: Against the backdrop of the digital economy emerging as the core driving force of global economic growth, digital infrastructure and innovation vitality have become key factors influencing regional economic development. Based on provincial panel data from 2005 to 2023, this paper constructs multiple linear regression and panel data models to empirically test the correlation mechanism and heterogeneous characteristics among the three. The research shows that digital infrastructure directly drives economic growth by optimizing resource allocation, empowering industrial upgrading, and expanding market scale, while innovation vitality fuels economic development with technological, model, and institutional innovation as the core, and there is a mutually reinforcing synergistic effect between the two. Heterogeneity analysis reveals that regions with low per capita GDP and western regions exhibit a more significant economic response to digital infrastructure, while eastern regions present a two-wheel-driven pattern of digital infrastructure and innovation vitality. On this basis, the paper proposes practical paths to promote the in-depth integration of the three from four dimensions: optimizing the regional layout of digital infrastructure, constructing differentiated innovation ecosystems, strengthening their synergy, and improving regional coordinated development policies, so as to provide theoretical reference and practical enlightenment for various regions to achieve high-quality development relying on the digital economy.
