基于2008—2022年60个“一带一路”沿线国家的面板数据，采用双重差分模型因果评价“一带一路”倡议对沿线国家科技创新的影响及其作用机制。结果表明：“一带一路”倡议显著推进了沿线国家科技创新水平，其政策影响效应首先表现为一个即期的正向冲击，而后这种冲击效果呈现出先快速上升后波动下降的整体趋势；“一带一路”倡议通过推进沿线国家在贸易、投资及经济领域的发展水平实现了其科技创新；中国对沿线国家科技创新作用机制主要通过扩大与沿线国家高技术产品双边贸易规模来实现。研究结论对推动中国及沿线国家科技创新及实现“一带一路”高质量发展具有一定的政策参考价值。
Based on the panel data of 60 countries from 2008 to
2022, a double difference model was used to causally evaluate the impact of the
“Belt and Road” initiative on science and technology innovation and its
mechanism of action in the countries along the route. The results show that： The “Belt and Road” initiative has significantly advanced the level of science
and technology innovation in the countries along the route, and its policy
impact is first manifested as an immediate positive shock, which then shows an
overall trend of rapid increase followed by fluctuation and decrease. The “Belt
and Road” initiative enables science and technology innovation in countries
along the route by advancing their level of development in the areas of trade,
investment and economy. The mechanism of China’s role in science and technology
innovation for the countries along the route is mainly achieved by expanding
the scale of bilateral trade in high technology products with the countries
along the route. The findings of the study are of policy reference value in
promoting science and technology innovation in China and other countries along
the “Belt and Road”, and in achieving quality development along the “Belt and
Road”.
