数字经济对共同富裕的影响研究——基于面板回归模型的实证分析

Research on the Impact of Digital Economy on Common Prosperity:Empirical Analysis Based on Panel Regression Model

数字经济已成为我国经济增长的新动力,是实现共同富裕的关键力量。选取2011—2020年全国31个省份面板数据,采用主成分法和熵值法测算共同富裕水平,用面板回归模型分析数字经济对共同富裕的影响效应,进而运用中介效应模型探讨研发投入与技术创新作为中介变量的间接影响,最后进行异质性分析。研究发现:数字经济对共同富裕具有正向影响作用,数字经济对共同富裕的影响作用存在时间异质性和区域异质性,研发投入和技术创新是影响共同富裕水平的重要机制。基于此,提出建立健全数字经济监管机制、夯实数字基础建设、实施差异化的数字经济发展策略等建议。

The digital economy has become the new driving force of China's economic growth and a key force in realizing common prosperity.The panel data of 31 provinces in China from 2011 to 2020 are selected to measure the level of common prosperity by principal component method and entropy value method,analyze the impact of digital economy on common prosperity,explore the indirect effect of R&D investment and technological innovation as intermediary variables by intermediary effect model,and finally analyze the heterogeneity.The study finds that the digital economy has a positive impact on the common prosperity,there are temporal and regional heterogeneity in the impact of the digital economy on the common prosperity,and R&D investment and technological innovation are important mechanisms that affect the level of common prosperity.Based on this,it is proposed to establish and improve the digital economy supervision mechanism,consolidate the digital infrastructure,and implement differentiated digital economy development strategies.
