The Relationship between Pollutant Emission and Economic Development in Shandong Province

With the Environmental Kuznets Curve(EKC),the relationship between environmental pollutant emission and economic development in Shandong Province was studied in this paper.The environmental pollution indexes included the effective emissions of industrial wastewater,SO2,smokes,and industrial total solid wastes.Based on the cubic polynomial regression analysis with GDP per capita as independent variable,EKC model was established to describe the changing trend of environmental pollution indexes from 1981 to 2006.The main results are as follows:(1) The Environmental Kuznets Curves of all of the four environmental pollution indexes present an N-shaped pattern.(2) Emissions of industrial wastes have passed through the peak turning points of Environmental Kuznets Curves,which means environmental pollution has been improved in recent years.During the period from 2004 to 2006,the environmental pollution is situated at the valley turning point,which means the emissions of industrial waste may rebound in the future.(3) The complex interactions are determined by such two characteristics as industrial structure and environmental protection policy.For sustainable development,industrial structure should be optimized to reduce the proportion of pollution industries,meanwhile,policies in finance,taxation,and environmental protection should be improved and investment for pollution prevention should be increased.
