But the concern of the haze problem breaks the original level of development of regional economic development by dividing the regional boundaries, showing regional differences. In this paper, we use the multiple regression models to study the difference of haze in 31 provinces and cities. The results show that there is a significant positive correlation between haze attention and purchase decision of consumers' haze protection products. The relationship between haze attention and education, air quality and per income is significant. Suggestions: encouraging public participation, building a collaborative governance environment; increasing awareness of haze knowledge; enhancing the technical level of haze protection products.
