Modification of Environmental Kuznets Curve based on Other Environment Variables

In this paper,we generalize the Environmental Kuznets Curve by replacing single environmental variable for nonlinear function of some environmental variables in Environmental Kuznets Curve( GK model). And we compare two different fitting results from the original model of Environmental Kuznets Curve and the modified Environmental Kuznets Curve to Liaoning province economic related data since 1988—2012. The results show that the Environmental Kuznets Curve on wastewater can be attached a linear combination to other environmental variables,and the modified Environmental Kuznets Curve on exhaust emission can more accurately predict the future change.
