数字经济、新质生产力与区域经济高质量增长

Digital Economy, New Quality Productivity and High-Quality Regional Economic Growth

摘要: 数字经济作为经济增长的驱动力，其以数字化为核心渗透于国民经济发展。文章基于2011~2023年我国31个省份的数据，运用多种面板模型，探究数字经济对经济高质量增长的影响。研究结果显示：数字经济能够推动区域经济高质量增长，这种影响通过了内生性和稳健性检验。机制检验发现，新质生产力在数字经济对经济高质量增长的影响中发挥中介作用，且新质生产力水平的高低会对这种结果产生差异。异质性分析显示，数字经济对经济高质量增长的影响存在地理区位差异性以及时间异质性。在拓展性分析中，技术创新作为门槛变量，其数值超过一定阈值时，数字经济能够显著促进经济高质量增长。

Abstract: As a driver of economic growth, digital economy permeates national economic development with digitization at its core. Based on the data of 31 provinces in China from 2011 to 2023, the article utilizes a variety of panel models to explore the impact of digital economy on high-quality economic growth. The results of the study show that the digital economy can promote the high-quality growth of the regional economy, and this impact passes the endogeneity and robustness tests. The mechanism test finds that new quality productivity plays a mediating role in the impact of the digital economy on high-quality economic growth, and this impact varies according to the level of new quality productivity development. The heterogeneity analysis shows that there is geographic location variability as well as temporal heterogeneity in the impact of the digital economy on high-quality economic growth. In the expansiveness analysis, technological innovation is used as a threshold variable, and the digital economy can significantly promote high-quality economic growth when its value exceeds a certain threshold.
