Abstract：The agglomeration theory holds that population agglomeration may affect the degree of haze pollution through externalities， and because of spatial heterogeneity， the traditional spatial homogeneity hypothesis is difficult to express the complex nonlinear relationship between the two. Therefore， this paper selects the panel data of 202 prefecture-level cities in China from 2003 to 2016， and uses the spatial panel Dubin model and the panel threshold model to empirically test the nonlinear spatial relationship between population agglomeration and haze pollution. The res show opulation agglomeration has obvious spatial spillover effect on smog pollution， and the spillover effect between regions is greater than the effect within the region. The impact of population agglomeration on smog pollution has the threshold characteristics. Before crossing the threshold value of 3.961， population gatherings aggravate smog pollution； after crossing the threshold， the impact of population agglomeration on smog pollution appears marginal decline. Therefore， it is proposed that the government needs to formulate a scientific joint prevention and control policy， focus on the spatial spillover effects of population agglomeration on smog pollution， and flexibly deal with the policy recommendations on the non-linear relationship between population agglomeration and smog pollution.
