对外贸易与环境的关系是当今国际经济学界的研究重点。对外贸易影响我国环境具有三种效应:结构效应、技术效应和收入效应,借助以我国的工业废气排放量作为环境污染指标,采用1991——2007年相关的环境、经济、贸易数据,建立计量回归模型,对贸易影响我国环境的三种效应进行实证分析。得出的结论是:对外贸易对我国环境污染的结构效应和技术效应均为正,而收入效应为负,因此总体上对外贸易对我国的环境污染有负的影响。
The relationship between foreign trade and the environment is the focus of research in the international economics community today. Foreign trade affects China’s environment with three effects: structural effects, technological effects, and income effects. With the use of China’s industrial emissions as an indicator of environmental pollution, the relevant environmental, economic, and trade data from 1991 to 2007 are used to establish a quantitative regression. The model empirically analyzes the three effects of trade on China’s environment. The conclusion is: The structural and technical effects of foreign trade on China’s environmental pollution are positive, and the income effect is negative. Therefore, overall foreign trade has a negative impact on China’s environmental pollution.
