国际贸易与环境的关系一直是学术界的热点话题。本文运用江苏省1991～2010年进出口贸易、外商直接投资、国内生产总值和SO2排放量的数据,采用协整检验与方程、格兰杰因果关系检验实证分析了江苏省国际贸易对环境的影响。得到了以下结论:第一,协整检验发现发现二氧化硫排放量与外贸依存度和外资依存度之间存在正的协整关系;第二,格兰杰因果关系检验的结果表明外贸依存度是导致江苏省环境质量变化的格兰杰原因,外资依存度不是导致江苏省环境质量变化的格兰杰原因。针对结论提出了几点建议。
The relationship between international trade and the environment has always been a hot topic in academia. Based on the data of import and export trade, foreign direct investment, GDP and SO2 emissions of Jiangsu Province from 1991 to 2010, this paper empirically analyzes the international trade of Jiangsu Province on the environment using the cointegration test and equation, Granger causality test influences. The following conclusions are obtained: First, the cointegration test found that there is a positive cointegration relationship between sulfur dioxide emissions and foreign trade dependence and foreign investment dependence; second, the result of Granger causality test shows that the dependence on foreign trade is the result of The Granger Reason for the Change of Environmental Quality in Jiangsu Province and the Degree of Foreign Capital Dependence are Not the Granger Causes for the Change of Environmental Quality in Jiangsu Province. In view of the conclusions made a few suggestions.
