摘要: 本文根据世界银行2008年高收入、中等收入和低收入的划分标准,选择了22个高收入国家、17个中等收入国家和13个低收入国家,结合这些国家1980-2009年人均GNI和能源消耗数据,利用能源库兹涅茨曲线分析法,分别拟合了这些国家的能源库兹涅茨曲线,并确定了各自的拐点,归纳了不同收入水平国家的能源库兹涅茨曲线的变动特征,得出了随着收入水平的提高,各国EyKC由“倒U型”左半部上升通道逐步向顶部趋近,直至进入EyKC的下降通道的结论。

Abstract: According to the criteria established by the World Bank in 2008 for classifying high-income, middle-income and low-income countries, the article selected 22 high-income countries, 17 middle-income countries and 13 low-income countries. With the data of GNI per capita and energy consumption of these countries from 1980 to 2009, using the method of energy Kuznets curve analysis, the article fitted energy Kuznets curve of each selected country and calculated their turning points. As a result, the changing characteristics of energy Kuznets curve of countries with different income levels were generalized. The conclusion was that with the increase of income, energy Kuznets curves of different countries were shown as approaching gradually to the top from the left ascending channel of the “inverted U” then changing to the descending channel.
