摘要(Abstract)：

本文利用中国对外援助和各国数字经济发展水平的相关数据，实证检验了中国与数字经济相关的对外援助对当地数字经济发展水平的影响。本文发现，中国在数字经济方面的对外援助能够显著促进当地数字经济发展。在子样本分析、倾向得分匹配、工具变量法等一系列稳健性检验中，该结论依然成立。异质性检验表明，对于那些被中国援助的累积金额相对较高、经济发展水平相对较高、贫困程度相对较低、服务业发展水平相对较差、初始数字经济发展水平相对较低的国家而言，中国援助对数字经济的促进效应更显著。在同一国家内部，中国对外援能助能促进男性、25岁及以上、受教育水平相对较高、相对富有和就业人群更多参与数字经济交易。进一步的机制分析结果表明，中国与数字经济相关的对外援助主要通过提高当地互联网普及率来推动数字经济的发展。最后，中国在数字经济方面的援助能够降低当地的收入不平等程度，这对于改善收入不平等这一全球治理问题具有重要意义。

• (1)由后文的模型设定可知,在考虑援助项目影响滞后性的情况下,本文所定义的中国对外援助指标为国家/地区当年之前是否受过中国对外援助的虚拟变量。因此,虽然中国对外援助的数据仅截止到2017年,但是这不会影响数据的合并。此外,在稳健性检验中,本文剔除2021年样本的估计结果后仍然稳健。
