摘要
本文采用固定效应——工具变量法对2004—2010年我国281个地级城市的人均二氧化硫排放量、人均废水排放量和人均烟尘排放量进行环境库兹涅茨曲线(EKC)假说检验。结果发现:环境质量与经济增长之间确实存在倒U型曲线关系,且人均二氧化硫排放量、人均废水排放量和人均烟尘排放量的环境库兹涅茨曲线拐点所对应的人均GDP分别是15190元、14449元和5743元。目前,大部分城市已经接近或越过拐点;同时,当前城市化对于环境质量有着显著的改善效应。据此,本文提出了相应的政策建议。
This paper estimates the Environmental Kuznets Curve （EKC） for SO2 emissions per capita,wasted water per capita and dust and fume emissions per capita by employing the fixed effected instrumental variables models based on a panel data set of 281 prefecture-level cities of China from 2004 to 2010. Firstly,it shows that the inverted U-curve relationship between economic growth and environment is significant and the turning points for SO2 emissions per capita, waste water per capita and dust and fume emissions per capita are 15190RMB, 14449RMB and 5743RMB respectively. At present, more and more Chinese cities are close to or even cross the EKC turning point. Meanwhile, urbanization has a positive effect on environment improvement. On this basis, this paper gives relative policy implications.
