不同地理特征下出口贸易对大气污染的影响研究

Research on the impact of export trade on air pollutionbased on geographical features

经济贸易全球化的高速发展,导致商品的生产地与消费地相分离.文中选取了中国287个地级市2004—2018年的数据构建了计量模型,研究出口贸易对中国大气污染的影响效应,重点增加了地理区位条件的影响因素,并对比“新常态”前后变化.研究表明:出口贸易对大气污染的影响显著为正,同时,经纬度等地理条件不同地区的出口贸易,对大气污染的影响程度也不同;“新常态”发展时期,中国大气污染治理效果十分显著.最后,提出了调整出口贸易主要产品结构、注重发展环境友好型产业、重视地理区位条件对产业发展影响、优化探索区域协同治理路径等对策建议.

The rapid development of economic globalization has separated the places where commodities are produced and consumed.China mentioned the concept of“new normal”in May 2014 and proposed the carbon peaking and the carbon neutrality goals in 2020,which attaches more importance to the sustainable development of society.This paper constructs an econometric model based on data about 287 prefecture-level cities in China from 2004 to 2018,and studies the impact of export trade and geographic conditions on air pollution in China and compares the changes before and after the“new normal”.The study reveals that the impact of export trade on air pollution is significantly positive.Different geographical location conditions,such as latitude and longitude,have different impacts on air pollution.During the development period of the“new normal”economy,the effect of air pollution control has been very significant in China.In the end,this paper puts forward suggestions on adjusting the main product structure of export trade,developing environmentally friendly industries,paying attention to the impact of geographical conditions on the environment,optimizing and exploring regional collaborative governance paths,etc.
