【摘要】 本文利用非洲17个国家2010—2019年数据，采用多时点双重差分方法，实证研究中国对非洲援建的6条铁路通车运营对非洲国家经济增长的影响。结果表明，中国在非洲援建铁路的开通运营能显著促进非洲国家经济增长，这一结论在进行了稳健性检验后依然成立。据此，中国应继续拓宽与非洲在基础设施建设领域的合作，推动中国铁路标准立足非洲，并考虑外部挑战，让中国工程走向世界。更多还原

【Abstract】 Based on the data from 17 African countries from 2010 to 2019,this paper empirically studies the impact of the operation of six railways built by China on economic growth in African countries by using the difference-in-differences method at multiple time points.The results show that the operation of China-aided railways in Africa can significantly promote economic growth in African countries,and this conclusion is still valid after the robustness test.Accordingly,China should continue to expand cooperation with Africa in the field of infrastructure construction,promote the establishment of China’s railway standards in Africa,and consider external challenges to make China’s projects go global.更多还原
