Export trade not only drives China＇s economic growth, promotes industrial upgrading and technological progress, but also may have a negative impact on the environment. After reviewing and summarizing the existing relevant literatures, tire paper collects the required statistic data from 2003 to 2006 and uses the panel data model to measure the environmental effects of export trade in the Yangtze River Delta. The results show that the export trade of Yangtze River Delta has a negative impact on the environment. When the variables of economic scale, economic structure areftxed, with the export trade growth of 1%, the industrial sulfur dioxide emission and industrial waste water emtsston will increase by 0.12% and 0.23% respectively. So we must pay serious attention to the negative effects, and promote regional sustainable development rapidly through adjusting the export structure and strengthening environmental regulations.展开更多
