| 基于2011—2022年长三角地区41个地级市的面板数据,构建评价指标体系,实证分析了数字经济对外贸高质量发展的影响效应及机制。结果表明,一方面数字经济能直接促进长三角地区外贸高质量发展。另一方面数字经济可以通过产业结构升级、技术创新和人力资本水平的提高等渠道,助推长三角地区外贸高质量发展。此外,异质性分析表明,数字经济的发展水平对中心城市以及GDP增速高的城市的外贸高质量发展起到了更为显著的推动作用。基于此,长三角地区应加强数字基础设施建设、促进产业结构升级、大力推动技术创新、提升人力资本水平,以更好地发挥数字经济对外贸高质量发展的促进作用。 |
| English Summary: |
| Based on panel data from 41 prefecture level cities in the Yangtze River Delta region from 2011 to 2022, an evaluation index system was constructed to empirically analyze the impact and mechanism of the digital economy on the high-quality development of foreign trade. The results indicate that on the one hand, the digital economy can directly promote the high-quality development of foreign trade in the Yangtze River Delta region. On the other hand, the digital economy can promote the high-quality development of foreign trade in the Yangtze River Delta region through channels such as upgrading industrial structure, technological innovation, and improving human capital levels. In addition, heterogeneity analysis shows that the level of development of the digital economy plays a more significant role in promoting the high-quality development of foreign trade in central cities and cities with high GDP growth rates. Based on this, the Yangtze River Delta region should strengthen the construction of digital infrastructure, promote industrial structure upgrading, vigorously promote technological innovation, and enhance human capital level, in order to better play the role of digital economy in promoting high-quality development of foreign trade.. |
