Abstract:

Based on the economic and industrial pollution data in ChangshaZhuzhouXiangtan region in the period from 1990 to 2006,a quantitative model was proposed to analyze the relationship between economic growth and the change of industrial pollution.In ChangshaZhuzhouXiangtan region,a heavy industry district,the environmental degradation has been partially controlled with the economic growth since 1990.The relationship between some environmental indicators and GDP per capita in Changsha City shows itself like an Environmental Kuznets Curve (EKC).However,the relationships between some environmental indicators and GDP per capita in Zhuzhou and Xiangtan City unfold like the “U” curve.It appears that the industrial pollution has been improved to some extent,but it rebounded subsequently.In order to further promote coordinate development of environment and economy in the three cities,some measures should be adopted.On the one hand,the government should take measures to adjust industrial structure and optimize industrial arrangement continuously.On the other hand,the government should carry out some positive systems and policies of environmental protection,such as “emission trading institution” and “beneficiary pays” principle etc.
