而对许多这类国家来说，近20年来的经济增长由两方面组成：一是过去遭遇了经济乱局（比如拉美）或者政治冲突和内战（比如非洲）后产生的自然反弹，二就是商品价格的提升。 而这两点都无法为发展中国家带来急需的生产力转型��
For too many of these countries, economic growth in the last two decades relied on a combination of two factors: a natural rebound from previous financial crises (as in Latin America) or political conflicts and civil war (as in Africa), and high commodity prices.  Neither can be relied on for the productive transformation that developing countries need.
