摘要
环境库兹涅茨曲线揭示了环境污染与人均收入水平之间存在倒“U”形关系,20世纪90年代后,西方环境经济学界的许多研究不断证实或充实这一结论。本文基于环境一收入的库兹涅兹曲线关系假设,采用面板数据模型对1985—2004年我国29个省(市、自治区)六类环境指标与人均收入的关系进行实证研究,发现人均粉尘排放量、人均SO2排放量和人均烟尘排放量三种指标随人均收入变化呈现先上升后下降的倒“U”形库兹涅茨曲线,而人均废水排放量、人均固体废弃物产生量和人均废气排放量随收入变化呈现单调上升的一次曲线;各类环境污染指标随收入变化的转折点出现位置有所差异,而我国环境污染指标随收入变化存在明显的地区差异。
The Environmental Kuznets Curve (EKC) assumes that there is an inverted "U" relationship between environmental pollution and per capita income. Since 1990"s, many approaches of western environmental economists have confirmed and substantiated the conclusion. Based on the EKC hypothesis and with panel data model, this paper demonstrates the relationship of six kinds of environmental indexes with the per capita income of 29 provinces of China from 1985 to 2004, and finds the curves which per volume of dust discharged, per volume of SO2 emission and per volume of soot emission change with the per capita income take on inverted "U" Kuznets Curve, while the curves that per volume of waste water discharged, per volume of waste residue produced and per volume of waste gas emission change with the per capita income take on flat ascending linear equation curve,the turning points of the curves which all kinds of environmental pollution indexes change with the per capita income are different, and in China the curves that environmental pollution indexes change with the per capita income take on obvious regional differences.
