广东省环境库兹涅茨特征分析

介绍了环境库兹涅茨假说经验结论,对其所涉及的环境质量随着经济增长出现"先恶化,后改善"的现象进行了分析,指出环境质量的变化不会自动产生,必须在环境政策的干预下才能实现.结合广东省废水、废气以及COD_Cr和SO₂等污染物排放量及经济增长数据,构建了广东省环境库兹涅茨曲线,实证分析了广东省经济增长与环境质量之间的关系;经过"十五"以来的环境综合整治,广东省废水和废气排放总量正在并将逐渐继续下降,部分环境指标正在接近转折点. 

The Environmental Kuznets Curve of Guangdong Province

The assumption of Environmental Kuznets and its inverted-U curve, which tells that the environmental quality will be deteriorated and then improved along with the economic growth, is introduced. It is also analyzed how the inverted-U curve is formed. The environmental quality will not be improved automatically except by interference of environmental policies. Based on the experimental analysis of Guangdong Province, the relationship between economy and environment is examined, by using the emission data of wastewater, waste gas, CODcr and SO2 into modeling. It shows that the emission is accelerated in the past twenty years and the emission of some pollutants is near the turning point, which means that the emission would decrease with the economic growth. The improved environmental performance is due to the enhanced integrated environmental control in the last five years.
