数字经济对新质生产力的影响研究

Research on the Impact of Digital Economy on New Quality Productivity

在当前全球化和信息技术快速发展的背景下,新质生产力已成为推动经济社会高质量发展的关键动力。为了深入探讨数字经济对新质生产力的影响作用,本文构建了评估数字经济和新质生产力的指标体系,利用2011至2022年中国30个省份的平衡面板数据,采用双向固定效应模型进行了实证分析。分析结果显示,数字经济对新质生产力的发展具有显著的正向影响。为了验证这一结论的稳健性,本文进一步进行了剔除特殊样本等一系列稳健性检验,结果表明该结论依然成立。此外,本文还发现数字经济在不同区域对新质生产力发展的促进作用存在异质性:在东部、西部和中部地区,数字经济显著促进了新质生产力的发展;而在东北部地区,这种促进作用并未达到统计学上的显著性水平。Under the background of current globalization and rapid development of information technology, new quality productivity has become a key driving force to promote high-quality economic and social development. In order to deeply explore the impact of digital economy on new quality productivity, this paper constructs an index system to evaluate digital economy and new quality productivity, and uses the balanced panel data of 30 provinces in China from 2011 to 2022 to conduct empirical analysis by two-way fixed effect model. The results of the analysis show that the digital economy has a significant positive impact on the development of new quality productivity. In order to verify the robustness of this conclusion, this paper further conducts a series of robustness tests such as excluding special samples, and the results show that this conclusion is still valid. In addition, this paper also finds that the promotion effect of digital economy on the development of new quality productivity in different regions is heterogeneous: in the eastern, western and central regions, digital economy significantly promotes the development of new quality productivity. However, in the Northeast region, this promotion effect does not reach a statistically significant level.
