柳州市经济发展与环境污染的关系

用库兹涅茨模型研究了柳州市经济发展与环境污染之间的关系并对其拐点进行了分析。结果表明：柳州市经济发展与环境污染之间符合三次曲线y=a＋bx＋cx2＋dx3＋ξ的＂U＋倒U＂形模型,且现在柳州市的经济水平已经跨越了第2个拐点,环境污染正随着经济的发展而呈现逐渐转好的趋势,但不够合理的产业结构和仍然处于工业化初中级阶段的经济可能导致柳州市经济发展与环境污染之间出现波动,即污染物排放量再次增加,影响柳州市环境质量的状况,因此提出了加大环保投入和优化产业结构等措施以预防或避免造成柳州市环境质量的降低。

Relationship Between Economic Growth and Environmental Degradation in Liuzhou

In order to ensure economic and environmental sustainable development,the relationship between economy development and environmental pollution in Liuzhou are studied based of the Kuznets model and the turning point is analysed.The result shows that the relation between economic development and environmental pollution is in line with the ＂U＋inverted U＂ model of the three curves y= a＋bx＋cx2＋dx3＋ξ,and now has crossed the second turning point.Environment is gradually becoming good.But industrial structure is not rational enough and industrialization is still in junior-high stage.It is possible to become fluctuation between economic development and environmental pollution with increasing pollutants emissions and affecting Liuzhou environment.So it is proposed to increase environmental protection investment and optimize industrial structure to prevent the deterioration of environmental quality in Liuzhou.
