本文考察了发达国家和发展中国家之间人均收入差距的演变情况。蓝士和库兹涅茨认为,西方国家的收入水平在其经济加速发展以前就已遥遥领先,但贝洛奇最近声称,十八世纪中叶,欧洲的生活水平比世界其他地方都低。我认为,现有的根据是支持蓝士—库兹涅茨观点的,贝洛奇或许是夸大了当代人收入的差距,缩小了发展中国家人均收入的增长。但证明材料中存在着相互矛盾的各种因素,还须作进一步的研究。 This article examines the evolution of the per capita income gap between developed and developing countries. According to Blue and Kuznets, income levels in Western countries are far ahead of their economies, but Beloit recently claimed that by the middle of the eighteenth century Europe was living less well than the rest of the world. In my opinion, the current support is based on the view of Minsk-Kuznets, who may have exaggerated the income gap among contemporary people and narrowed the growth of per capita income in developing countries. However, there are contradictory factors that prove the material, and further research is needed.
