国际贸易对中国环境污染的影响研究——基于面板数据动态GMM的实证分析

The influence of international trade on China’s environmental pollution--Dynamic GMM empirical analysis based on Panel Data

基于我国2004-2017年30个省级区域的面板数据,利用动态GMM模型的估计方法分区域考察了国际贸易对我国二氧化硫、废水、烟(粉)尘三类污染物排放量的影响,并使用熵权法将以上三种污染物构建为环境污染综合指数同时进行评估。实证结果表明:就全国范围而言,国际贸易加剧了我国的环境污染;分地区而言,国际贸易对不同污染物的影响呈现出不一致的表现。

Based on panel data of 30 provincial regions in 2004-2017,the impact of international trade on the emissions of sulfur dioxide,wastewater and smoke(powder)dust in China was investigated by using the estimation method of dynamic GMM model.The above three pollutants were constructed as the comprehensive index of environmental pollution by entropy weight method.The empirical results show that:in terms of the whole country,international trade intensifies the environmental pollution of China;in terms of different regions,the impact of international trade on different pollutants shows inconsistent performance.
