论经济增长与环境质量——评EKC曲线假说

On Economic Growth and Environmental Quality——Comment on the Hypothesis of Environmental Kuznets Curve

环境库兹涅茨曲线(EKC)假说认为,环境质量随经济增长存在"先恶化、后改善"的趋势。许多学者曾对该假说进行实证检验。但到目前为止,各种实证研究的结果非常不一致,环境质量除了受经济规模的影响外,经济增长过程中的其他因素也会对环境质量产生间接的影响。通过制度创新和技术变革,人类可以在获得经济增长的同时享受良好的环境质量。

According to the hypothesis of Environmental Kuznets Curve, environmental quality changes with the economic growth, showing the tendency of ＂ deteriorating first, and improving later＂. Many scholars carry out authentic examination of this hypothesis. But to date, the findings of this kind of examination have been inconsistent, and the implications of EKC are diversifies in the academic circle. In fact, environmental quality is influenced not only by economic scale, but other factors also contribute to it indirectly. Among these factors, some are negative, others are positive. Through institutional creation and technical reform, people can get a better environmental quality as well as economic growth.
