Abstract As one of the negative external products of urbanization and industrialization, haze pollution is undoubtedly affected by urban sprawl. At the same time, improving the quality of urban innovation and reducing haze pollution is a proper part of implementing the new development concept, and urban sprawl has become an essential factor affecting high-quality urban development. Therefore, based on urban panel data of 269 prefecture-level cities in China from 2004-2018, this paper uses a dynamic spatial Durbin model to examine the impact of urban sprawl and innovation quality on haze pollution. The results show that haze pollution has the effect of time stickiness and spatial mobility, and urban sprawl significantly promotes haze pollution, while urban innovation quality has a suppressive impact on haze pollution. Meanwhile, the interaction between urban sprawl and innovation quality substantially promotes haze pollution, indicating that urban sprawl weakens the haze reduction effect of innovation quality. Further study finds that local urban sprawl enabled haze pollution in neighboring areas, and local innovation quality significantly impacted haze pollution in adjacent areas.
