青岛市环境库茨涅茨曲线实证分析

环境库茨涅茨曲线（EKC）假说是指在经济发展早期环境质量逐渐恶化,经济发展到一定水平后,环境质量会逐渐改善,即环境指标和经济增长之间呈倒U形关系。通过对青岛市环境库茨涅茨曲线分析,发现青岛市的废水、废气、粉尘和固体废物排放量等主要环境指标都与GDP呈现显著相关性,但只有废水排放量与人均GDP的关系符合倒U型,并即将达到转折点,但该转折点按购买力均价计算远高于西方国家,而废气和固体废物等污染物排放处于快速上升的通道,不符合倒U型关系。

An Empirical Study on EKC in Qingdao

The hypothesis of Environmental Kuznets Curve(EKC) is that the environmental quality would improve due to the economic development after a worsening process in early years of the economy,that is to say,there would be inverse U-shaped relationships between the environmental indexes and economic growth.Basing on the environmental Kuznets curves,a model was built to study the relationship between the environment and development of Qingdao.The main environmental indexes,such as the emissions of waste water,exha...
