Abstract: Based on the study of the relationships between economic growth and in dustrial pollutant discharge of Suzhou City in 1991〖KG-*2〗-〖KG-*7〗2005, the environmental Kuznets curve (EKC) of the City was estimated by several kinds of function, with the cause analyzed. The results showed that the EKC of Suzhou was not a typical one. The industrial pollution of the City increased dramatically by scale effect of economic growth and the clear environmental benefit of indust rial structure adjustment was not received obviously, while generalized discharg e reduction technologies showed great results. In general terms, the pollution i ncrease was comparatively slower than the GDP growth. As a whole, the environmen tal policy of Suzhou was in effect. However, the relationships between economic growth and industrial pollutant discharge had not been a benign development yet. In order to achieve win-win situation of economic growth and pollution reducti on, Suzhou needed to optimize its industry structure, push the energy conservati on and discharge reduction policy deeply, increase environmental investment, and enforce the strictest environmental and industrial policy. In doing these, Suzh ou could turn the traditional ∩-shaped EKC into ∧-shaped EKC.
