Abstract Taking 21 urban agglomerations in China as the research object, this paper first measures the polycentric spatial structure of urban agglomerations from the three aspects of scale, location and accessibility, and then uses the two-way fixed effect model to identify the impact of polycentric spatial structure of urban agglomerations on haze pollution. Thirdly, the index system is constructed from the three dimensions of function, institution and culture to measure the integration level of urban agglomeration. Finally, the regulatory effect of urban agglomeration integration level on the impact of polycentric spatial structure on haze pollution is examined in this paper, that is, the heterogeneous impact of polycentric spatial structure on haze pollution under different urban agglomeration integration levels is analyzed. The results are as follows: (1) The polycentric spatial structure of urban agglomeration can obviously alleviate haze pollution; (2) The integration of urban agglomeration has a positive promoting effect on the mitigation of haze pollution by polycentric spatial structure. And from the aspects of functional, institutional and cultural integration, the conclusion is still valid. This means that by strengthening the construction of polycentric system of urban agglomeration, we can alleviate the haze pollution caused by excessive concentration of economic activities in a single central city, improve the level of integration of urban agglomerationand further promote the emission reduction effect of polycentric spatial structure.
