中文摘要：

从污染物处理的角度出发，通过构造理论模型，分析了外国直接投资对污染物处理率的影响。研究发现，外国直接投资对东道国污染物处理率的影响取决于外国直接投资的技术优势和东道国的环境管制。在东道国存在环境管制或外国直接投资具有技术优势的前提下，外国直接投资的进入将导致东道国污染物处理率的提高。为了验证这一结论，利用中国东部地区2005~2009年的省级数据进行了实证分析。

英文摘要：

While many lectures have focused on the effect of FDI on enviroments in host countries, most of these studies discussed the relationship between FDI and pollutants emission and pollutants treatment has almost been omitted. In this paper, we construct a theoretial model to study the relationship between FDI and pollutants treatment and find that when either advanced technology brought by FDI or envrionmental regulation of host countries exists,FDI improves pollutants treatment. The results of empirical analysis also support this conclusion, using the data of coastal provinces in China from 2005 to 2009.
