中国对非洲国家直接投资的影响效应研究

Study on the Impact of China's Direct Investment in African Countries

中国对非洲地区顺梯度资源寻求型直接投资在促进自身贸易高质量发展的同时,也推动着非洲东道国经济增长。为考察中国OFDI对非洲经济增长的影响效应,以2003-2018年中国对非洲48个国家直接投资的面板数据为样本,运用动态面板GMM估计方法和静态面板回归法对中国OFDI对非洲国家产生的经济效应进行实证研究。结果表明:中国OFDI对非洲相关国家经济增长总效应为0.1421%,直接效应为0.1035%,间接效应为0.0386%,中介效应为27.15%。中国OFDI不仅直接促进了非洲经济增长,而且通过改善非洲医疗健康水平推动该地区经济发展。研究还发现,中国OFDI对非洲经济增长效应因区域不同而存在明显差异。具体而言,对东非区域国家经济增长拉动作用最明显,其次是南非区域和北非区域,对中非和西非区域国家作用较弱。

While promoting the high-quality development of China's trade,direct investment in African region along the gradient of resource-seeking foreign direct investment(OFDI)promotes the economic growth of African host countries.This paper construct a panel dataset of China's direct investment in 48 African countries from 2003 to 2018 to examine the impact of China's OFDI on economic growth in Africa by using G M M estimation method and static panel regression method.The results show that the total effect of OFDI is 0.1421%;the direct effect is 0.1035%,while the indirect effect is 0.0386%,and the intermediary effect is 27.15%.China's OFDI not only contributes directly to Africa's economic growth,but also boosts the region's economy by improving Africa's health care conditions.In ad-dition,the study also finds that the effects of China's OFDI on Africa's economic growth vary significantly from region to region,with East Africa being the most important driver,followed by South Africa and North Africa,with weak impact on countries in the central and west African regions.
