数字经济如何重塑我国区域创新格局?——基于研发要素流动的视角

How the Digital Economy Reshapes Chinese Regional Innovation Structure:Based on the Perspective of R&D Factor Flow

本文基于新经济地理学“中心—外围”理论,从研发要素流动的视角,深入分析数字经济重塑区域创新格局的内在机理,并采用2011—2021年我国285个城市面板数据,实证考察区域创新格局的演变趋势,以及数字经济对区域创新格局的重塑效应。研究表明,考察期内我国区域创新存在收敛趋势,即区域创新格局趋于均衡;数字经济有利于缩小区域间创新差距,改善区域创新格局的非均衡状态。上述结论在更换不同权重矩阵、替换不同度量指标、考虑滞后效应以及剔除异常样本点后依然具有稳健性。机制检验结果表明,数字经济通过影响研发要素流动,改善区域创新格局非均衡状态,并促进区域均衡创新格局的形成。本文研究结论为深化数字经济改革,优化区域创新格局提供政策启示。

Based on the theory of new economic geography and the perspective of R&D factor flow,this paper analyzes the internal mechanism of digital economy affecting regional innovation structure.On this basis,using the panel data of 285 cities in China from 2011 to 2021,this paper empirically investigates the evolutionary trend of regional innovation structure and the impact of digital economy on regional innovation structure.According to the study,during the investigation period,there is a convergence trend in Chinese regional innovation,that is,the structure of regional innovation tends to be balanced.What's more,the digital economy has a significant positive impact on regional innovation convergence.Namely,digital economy can narrow the regional innovation gap and improve the balance of the regional innovation pattern.After replacing different weight matrices,measurement indicators,considering lag effect and eliminating abnormal sample points,these results are still robust.The mechanism test shows that the digital economy promotes the formation of regional balanced innovation pattern by affecting the flow of R&D factor.In the end,the conclusions of this paper provide useful inspiration for deepening the reform of digital economy and promoting the coordinated development of regional innovation.
