摘要
采用2010—2019年中国与各国开展进口贸易数据,以“一带一路”倡议的提出为事件冲击,通过构建双重差分模型,可以实证检验“一带一路”倡议对中国进口规模和进口质量的影响。研究发现,“一带一路”倡议的提出可以扩大中国的进口规模,且效果稳健;其进口扩张效应在国内各地区不存在显著差异,并且更有利于技术含量高、生产工序复杂的工业产成品以及零部件的进口。此外,对产品进口质量的实证检验发现,“一带一路”倡议的实施对产品质量有提升作用,同时能优化产品结构,从而对经济产生正向溢出效应。
This paper empirically examines the impact of the“Belt and Road Initiative”(BRI) on the scale and quality of China’s imports by utilizing the value of China’s imports from various states from 2010 to 2019 and by constructing a difference-in-difference model with the BRI as the event shock. It is found that the BRI has expanded the scale of China’s imports, and the effect is robust. In addition, the findings revealed that the import expansion effect of the BRI did not differ significantly across regions in China, and was more favorable to the import of industrial products with high technology content and complex production processes, as well as parts and components. Finally, the paper measured the quality of imports at the product level and found that the implementation of the BRI had a positive spillover effect on the economy by improving product quality, thereby optimizing product structure.
