数字经济与实体经济融合对经济高质量发展的影响研究——基于九大城市群的证据

Research on the Impact of the Integration of Digital Economy and Real Economy on High-Quality Economic Development—Based on Evidence from Nine Major Urban Clusters

摘要: 基于我国2011~2020年间九大城市群内138个城市的面板数据，本研究测度了我国数字经济与实体经济的融合程度，并实证分析了其对经济高质量发展的影响。研究指出，当前我国的数实融合水平仍处于中低度阶段。实证结果显示，数实融合对经济高质量发展具有显著的正向作用，且其高质量发展溢出效应随融合度与创新创业活动的提升而显著增强，呈现边际效应递增趋势。此外，数实融合对经济高质量发展的影响存在显著的维度异质性与区域异质性。本研究不仅增进了对经济高质量发展动因的认识，还深入探讨了数实融合在促进经济高质量发展中的具体效应及其地区间差异，为相关政策制定提供了一定的参考。

Abstract: Based on the panel data of 138 cities in nine major urban agglomerations in China during 2011~2020, this study measures the integration degree of digital economy and real economy in China, and empirically analyzes its impact on high-quality economic development. The research points out that the level of digital-real integration in China is still in the middle and low stage. The empirical results show that digital-real integration has a significant positive effect on high-quality economic development, and the spillover effect of high-quality development is significantly enhanced with the increase of integration degree and innovation and entrepreneurship activity, showing an increasing trend of marginal effect. In addition, the impact of digital-real integration on high-quality economic development has significant dimensional and regional heterogeneity. This study not only improves the understanding of the drivers of high-quality economic development, but also deeply discusses the specific effects of data and real integration in promoting high-quality economic development and its regional differences, and provides certain references for relevant policy formulation.
