环境库兹涅茨曲线存在吗?——来自CO_2排放量的国际数据验证

Does Environmental Kuznets Curve Exist?——The Empirical Study of International Data of CO_2 Emissions

从理论和实证两个角度探讨了经济增长和环境污染之间的关系。首先研究了环境库兹涅茨曲线(EKC)理论模型及其得到满足所依循的条件,其次运用1960～2005年206个国家和地区的CO2排放量和国民经济的面板数据,分高收入国家、中等收入国家和低收入国家验证了EKC,发现EKC的转折点为13,000美元左右。

This paper studies the relationship between economic growth and environmental pollution theoretically and empirically.First,the theoretical model and conditions of EKC are researched.Then,using data of CO2 emissions and the national economy in 206 countries and regions from 1960 to 2005,EKC of high-income,middle-income and low-income countries are tested respectively.It is found that the turning point of EKC is13,000 dollars.
