中国对外援助与受援国经济增长:兼论基础设施的中介效应

China’s Foreign Aid and Economic Growth of Recipient Countries:Analysis of the Mediating Effect of Infrastructure

文章基于Aiddata数据库中2003~2014年间中国对外援助的面板数据,实证研究了中国对外援助与受援国经济增长之间的关系。文章采用主成分分析法构造了衡量受援国基础设施水平的变量——基础设施指数,基于中介效应分析法,从理论和实证两个方面分析了对外援助对受援国经济增长的影响及作用机制。研究结果表明,中国对外援助的确显著地提升了受援国的经济增长水平,为中国对外援助的有效性增添了新的理论依据。对"对外援助—基础设施建设—经济增长"这条作用机制的验证发现,中国对外援助对受援国经济增长的总效应中,大约有55.30%是通过改善当地的基础设施水平来实现的,证明了中国对外援助能够显著推动受援国的经济增长。

Based on the panel data of China’s foreign aid in the AidData database from 2003 to 2014,this paper empirically studies the relationship between China’s foreign aid and the economic growth of recipient countries. The paper uses principal component analysis to construct the infrastructure index of recipient countries. Based on the mediation effect analysis method,it analyzes the influence and mechanism of foreign aid on the economic growth of recipient countries from both theoretical and empirical aspects.The research results show that China’ s foreign aid has significantly improved the economic growth level of recipient countries,which generates a new theoretical basis for the effectiveness of China’s foreign aid. According to the experimental test of " foreigh aid-infrastructure development-economic growth" mechanism,we found that nearly 55.3% of the total effect of China’s foreign aid towards the economic growth of recipient countries was achieved by improving the local infrastructure.
