This paper analyzes the interaction between regional economic growth and air pollution in China and Korea. The relationship between gross regional product per capita and industrial emission of sulfur dioxide emission is examined at the regional level using simultaneous equation models covering 286 cities in China and 228 cities and counties in South Korea of the period 2006-2016. The results find that regional differences existed in the relationship between air pollution and economic growth in two countries. In both countries, an inverted U-shaped pattern was found in metropolitan areas while a U-shaped pattern of non-metropolitan areas. Although the emissions of pollutants in metropolitan areas of both countries have shown a downward trend in recent years, there is still a large gap between the overall emission levels of China and South Korea. Moreover, the level of pollutant emissions of China's metropolitan areas is much higher than in non-metropolitan areas, while the opposite result has occurred in Korea. In China, there was an inverted U-shaped relationship of the eastern and northwest region, while U-shaped relationships existed in the southwest, central and northeast regions.
本文分析了中国和韩国的区域经济增长与空气污染之间的相互关系。利用涵盖 2006-2016 年期间中国 286 个城市和韩国 228 个市、郡的联立方程模型，在区域层面上检验了人均地区生产总值与工业二氧化硫排放量之间的关系。结果发现，两国的空气污染与经济增长之间存在区域差异。在这两个国家中，大都市地区呈现出倒 U 型模式，而非大都市地区呈现出 U 型模式。尽管近年来两国大都市地区的污染物排放量呈下降趋势，但中国和韩国的整体排放水平仍存在较大差距。此外，中国大都市地区的污染物排放水平远高于非大都市地区，而韩国则相反。在中国，东部和西北地区呈现出倒 U 型关系，而西南、中部和东北地区则呈现出 U 型关系。
