Abstract: The central and southern region of Liaoning Province is the key area required in the State Council's Air Pollution Prevention and Control Plan. In this paper, the daily average PM2.5 index of central and southern Liaoning urban agglomeration in 2016 is used as the measurement index of haze pollution, and AR model is used to study the persistence characteristics of haze pollution in cities in central and southern Liaoning. Based on Granger causality test and ISM model, the mutual influence of haze pollution between cities is discussed. The empirical results show that the haze pollution between cities in central and southern Liaoning has a strong persistence and spatial spillover effect, and the spillage direction is from north to south, with Shenyang and other cities as the center. The increase in the haze concentration of a city in the urban agglomeration will have an impact on the surrounding cities. The joint prevention and control of central and southern Liaoning should consider the mutual influence of haze pollution between cities. By rationally setting up key areas of smog pollution and adjusting industrial layout, it can produce more effective governance results.

Key words: haze pollution; spatial spillover effect; Granger causality test; impulse response analysis; interpretative structural modeling
