This study examines the relationship between industrial agglomeration and industrial pollution. The empirical results for the entire sample show that industrial pollution has a significant spatial spillover effect. Specifically, for every 1% point increase in industrial pollution in neighboring regions, industrial pollution in the region increases by 0.33% points. Industrial pollution shows an inverse U-shaped change with industrial agglomeration. There is a significant positive linear relationship between domestic industrial agglomeration and industrial pollution. And there is a significant inverted U-shaped relationship between domestic industrial agglomeration and industrial pollution. Furthermore, heterogeneous results are observed among different urban agglomerations, with a significant inverse U-shaped relationship between industrial agglomeration and pollution in the Guangdong-Hong Kong-Macao-Great Bay Area, the Yangtze River Delta, and the Middle Reaches of Yangtze River and a significant U-shaped relationship in Beijing-Tianjin-Hebei.
本研究考察了产业集聚与工业污染之间的关系。整个样本的实证结果表明，工业污染具有显著的空间溢出效应。具体而言，邻近地区工业污染每增加1个百分点，该地区的工业污染就会增加0.33个百分点。工业污染与产业集聚呈现倒U形变化。国内产业集聚与工业污染之间存在显著的正线性关系。并且国内产业集聚与工业污染之间存在显著的倒U形关系。此外，不同城市群之间存在异质性结果，在粤港澳大湾区、长江三角洲和长江中游地区，产业集聚与污染之间存在显著的倒U形关系，而在京津冀地区则存在显著的U形关系。
