Haze has impaired the order of public health as well as normal social and economic development. Toanalyse the factors influencing PM2.5 in Jiangsu province and propose specific governance strategiesbased on time-series data in Jiangsu from 2000 to 2014, this study identified five factors that causehaze pollution in Jiangsu. A multiple linear regression model was adopted to quantitatively measure thedegrees of the effect of these factors and their significance levels. Specific measures that governhaze from the perspective of factors with significant influence were proposed. Findings show thatthe extensive economic growth mode, the sustainable growth of car ownership, heavy consumptionof coal, the large amount of exhaust emissions in industrial production, and the large amount of dustsgenerated by urbanization construction are the five major factors that influence the frequency of hazePM2.5 weather in Jiangsu. Car ownership, generation of dust by housing construction, and emissionof industrial exhaust significantly influence the frequency of PM2.5 weather. The regression coefficientsof the three independent variables were positive and effective at the 5% significance level, and thegrowths of the three independent variables per unit increase haze weather by 0.457, 0.248, and0.114, respectively. The findings of this study provide effective policy suggestions for analysing thefactors that influence haze weather, adopting specific governance measures for the haze problem,and implementing environmental protection measures in Jiangsu.
