中文摘要：
选取2000—2011年中国30个省份的面板数据,从贸易开放度与贸易结构两个方面考察出口贸易对空气污染的影响。结果发现：出口贸易开放度对PM2.5平均浓度的影响并不显著,但对地均SO_2排放量却具有显著的正效应,即出口贸易开放对不同空气污染物的影响可能存在地区差异;重工业出口比重的增加带来了PM2.5和SO_2污染情况的加剧,而高技术产业出口则存在着缓解效应。
英文摘要：
Using Chinese province -level panel data of 30 provinces from 2000 to 2011 in China, this paper explores the impact of experts on air pollution from both trade openness and trade structure aspects. The study shows that export trade openness has non - significant effect on the average concentration of PM2.5, but it has a significant positive effect on per square SO2 emissions, which means export trade has different effects on different air pollutants. In terms of the export trade structure, increasing of the proportion of heavy industry exports contributes to PM2.5 and SO2 pollution, while high -tech industrial exports mitigate two air pollutants.
