Abstract: Haze pollution is becoming more and more prominent in recent years with the development of China's economy. This article studies how different types of industrial agglomeration contribute to haze pollution. Based on a panel data of 264 Chinese cities from 2003 to 2016, a spatial econometric model was adopted to analyze the related variety and unrelated variety impact on haze pollution and further investigate the moderating effect of technological innovation. The results show that: (1) There is an inverted U-shaped relationship between related variety and haze pollution, however, the overall variety aggravates haze pollution. (2) Technological innovation can significantly alleviate haze pollution, and the level of technological innovation can strengthen the inverted U-shaped relationship between variety and haze pollution.
