摘　　要：在东中西部分别选择两个典型城市,分析环境库兹涅茨(EKC)曲线及其所处的阶段,从污染物排放、产业结构、技术水平、环境保护投资等几个方面,比较分析这些因素对EKC曲线的影响。结果表明:东部地区的两个城市已进入倒"U"型EKC曲线下降阶段;中部地区两个城市处于倒"U"型EKC曲线上升阶段的后期;西部地区两个城市处于倒"U"型EKC曲线的上升阶段。研究结果可为我国实现经济跨越式发展提供参考。With different level of economic development and environmental pollution, we select two cities separately in the east, middle and west of China, to analyze the feature of EKC and its stages from the aspects of pollutants discharge, industrial structure, technical level, environmental policies as well as environmental investment, comparing the influences of these factors. The results indicate that： two cities in the east of China have stepped into the decline stage of inverted-U curve; two cities in the middle of China are now in the later period of rise of inverted-U curve; two cities in the west of China are still in the process of rising of the inverted-U curve. All the research results can give some references to our government for economic great-leap- forward development.
