Abstract This paper examines economic growth in 52 African countries for 1961–2016 and seeks to find if there is common growth. As all African countries have their particular features, concerning climate, harvest, industry, size, politics, and infrastructure, and more, it seems best to rely on a non-parametric method. Dynamic Time Warping is such a convenient method, also as it allows leads and lags across countries to vary over time, and as it can easily be incorporated into a clustering technique. Five clusters are found, two of which concern Equatorial Guinea and Botswana, and the three other clusters have common growth rates of about 0, 2 and 4 over more than five decades.

非洲经济是否同样增长？

摘要 本文考察了 52 个非洲国家 1961-2016 年的经济增长，并试图找出是否存在共同增长。由于所有非洲国家都有自己的特点，在气候、收获、工业、规模、政治和基础设施等方面，似乎最好依靠非参数方法。动态时间扭曲是一种如此方便的方法，还因为它允许各国之间的领先和滞后随时间变化，并且它可以很容易地合并到聚类技术中。发现了五个集群，其中两个涉及赤道几内亚和博茨瓦纳，其他三个集群在超过 50 年的时间里具有大约 0、2 和 4 的共同增长率。
