Abstract: With the 1988-2002 economic and environmental data in Jiangsu Province as basis,the model of the industrial waste discharge per unit GDP and industrial waste discharge per capita GDP bave been established,and the relationship between typical environmental indexes and increase of GDP was analyzed.The results show that the industrial waste discharge per unit GDP displays a general downward trend,which indicates that the technological progress and readjustment of industrial structure have yielded significant environmental benefit;meanwhile on the whole the relationship of economic development and environmental pollution conforms to the characteristics of EKC.So the conclusion can be drawn that Jiangsu Province is still at the stage of industrial development,an EKC turning point of the environmental waste discharge has not yet reached.It is,therefore,necessary for Jiangsu to keep a high level of financial input into the control of environmental pollution.
