| 摘 要： 数字经济正成为推动共建“一带一路”高质量发展的重要引擎。基于2010—2019年共建“一带一路”国家的面板数据，首先从高标准、惠民生、可持续三个维度构建共建“一带一路”高质量发展水平评价指标体系，并测度沿线国家高质量发展水平；然后实证检验数字经济对共建“一带一路”高质量发展的影响效应及作用机制。研究发现：整体上看，数字经济对共建“一带一路”高质量发展存在显著推动作用，且随着高质量发展分位点位置的上升，推动作用逐渐增强；分样本看，相比中等偏上收入国家和中等偏下收入国家，数字经济对高质量发展的影响在高收入国家更显著，当然，在中等偏上收入国家和中等偏下收入国家，数字经济对高质量发展的影响不存在显著性差异，说明中等收入国家可通过数字经济发展来推动高质量赶超；作用机制分析显示，数字经济可以通过提升创新绩效和促进产业结构升级进而推动共建“一带一路”高质量发展。 |

| Abstract: Digital economy is becoming an important engine for promoting the high-quality development of the co-constructing of the Belt and Road. Based on the panel data of the countries jointly building the Belt and Road from 2010 to 2019, this paper first constructs the evaluation index system of the high-quality development level of the Belt and Road from such three dimensions as high standards, livelihood improvement and sustainability, and measures the high-quality development level of countries along the Belt and Road. Then, this paper empirically examines the heterogeneous impact and mechanism of digital economy on high-quality development of the co-constructing of the Belt and Road. The research finds that on the whole, the digital economy has played a significant role in promoting the high-quality development of countries along the Belt and Road, and that the role is gradually increasing with the rise of high-quality development quantiles. By the samples, the impact of digital economy on high-quality development is more significant in high-income countries than in upper-middle-income countries and lower-middle-income countries. Of course, there is no significant difference between upper-middle-income countries and lower-middle-income countries in the impact of digital economy on high-quality development, indicating that middle-income countries should also promote high-quality catch-up through digital economy development. The mechanism analysis shows that digital economy can promote high-quality development of the Belt and Road by improving innovation performance and boosting industrial structure upgrading. |
