摘　　要：基于对苏州市1991—2005年经济增长与工业污染物排放之间关系的研究,选用多种函数对苏州市的环境库兹涅茨(EKC)曲线进行估计,并分析原因.结果表明:苏州市的EKC曲线不具有典型特征;经济规模增长对苏州工业污染增加的贡献十分显著,产业结构调整因素还未产生明显环境效益,技术减排作用突出;与GDP增加相比,工业污染排放增量较为缓和.环境政策总体上具有成效,但苏州经济增长与工业污染排放关系仍未呈现良性态势.苏州要实现经济增长和污染削减的双赢,必须进一步优化产业结构,大力推进节能减排,加大环境保护投资力度,实行最严格的环境与产业政策,突破传统倒U型EKC曲线,实现新型的倒V型EKC曲线.Based on the study of the relationships between economic growth and industrial pollutant discharge of Suzhou City in 1991-2005, 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 industrial structure adjustment was not received obviously, while generalized discharge reduction technologies showed great results. In general terms, the pollution increase was comparatively slower than the GDP growth. As a whole, the environmental 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 reduction, Suzhou needed to optimize its industry structure, push the energy conservation and discharge reduction policy deeply, increase environmental investment, and enforce the strictest environmental and industrial policy. In doing these, Suzhou could turn the traditional ∩-shaped EKC into ∧-shaped EKC.
