日常的感知中,一部分中等收入国家发展速度很快,而另一些发达国家如英美德等却发展速度相对较慢。原因在于中等收入国家大多具有后发优势,因为这些国家大多具有劳动力丰富、制度变革优势,而这些优势使得中等收入国家将资源禀赋更好地发挥出来,获得相比发达国家更快的发展速度。 Of the daily perceptions, some middle-income countries have enjoyed rapid development while others, such as Britain, the United States, have enjoyed relatively slow growth rates. The reason is that most middle-income countries have the advantage of backwardness, because most of these countries have the advantages of labor-rich and institutional transformation. These advantages enable middle-income countries to better utilize their resource endowments and achieve faster development than the developed countries.
