| 中文摘要: |
| 数字经济为社会治理、居民生活、经济发展等领域带来了深刻的变革，逐渐融入到国民经济生活中并产生重要影响。文章基于中国30个省（市、自治区）2013-2020年的面板数据，运用固定效应模型、中介效应模型和空间杜宾模型等方法，实证检验了数字经济发展对地区经济的影响及其传导机制。研究发现，数字经济发展显著缩小地区之间的经济增长差距，运用工具变量估计、替换解释变量、剔除异常值等方法进行稳健性检验后，该结论依然成立。中介效应分析表明，地区创新能力是数字经济缩小地区间经济增长差距的重要机制。空间溢出效应分析表明，数字经济发展对邻近省份与发达地区的经济增长差距的缩小具有负向的溢出效应。空间异质性分析表明，东部、中部地区数字经济发展对地区经济增长差距的缩小效应相比西部地区更显著；南、北方的异质性分析表明，数字经济发展对地区经济增长差距的缩小均具有显著作用。为我国发展数字经济、充分发挥数字经济对缩小地区经济差距，实现区域协调发展提供理论依据和政策参考。 |
| English Summary: |
| Digital economy has brought about profound changes to social governance, residents"" life, economic development and other fields, and has gradually been integrated into the national economic life and has an important impact.Based on the panel data of 30 provinces (municipalities and autonomous regions) in China from 2013-2020, this paper uses fixed effects model, intermediary effects model and Spatial Dubin model to empirically test the effect of digital economy development on regional economy and its transmission mechanism.The study found that the development of digital economy significantly narrowed the economic growth gap between regions, and the conclusion was still valid after the robustness test by using the instrumental variables to estimate, replacing explanatory variables and excluding outliers.The intermediary effect analysis shows that regional innovation ability is an important mechanism for digital economy to narrow the economic growth gap between regions.Spatial spillover effect analysis shows that digital economy development has a negative spillover effect on the narrowing of the economic growth gap between neighboring provinces and developed regions.Spatial heterogeneity analysis shows that the effect of digital economy development in eastern and central regions is more significant on narrowing the regional economic gap than in western regions;the heterogeneity analysis of south and north shows that the development of digital economy plays a significant role in narrowing the regional economic growth gap..It provides theoretical basis and policy reference for China to develop digital economy and give full play to digital economy to narrow the regional economic gap and realize coordinated regional development. |
