Abstract

PurposeThe purpose of this paper is to explore the relationship among the air quality index (AQI) of Beijing-Tianjin-Shijiazhuang region and find countermeasures to control the pollution situation.Design/methodology/approachThis study used the grey convex relation model to calculate the grey correlation degree through the AQI of Beijing-Tianjin-Shijiazhuang region.FindingsBy analyzing the calculation results among the three cities, it was concluded that the air quality of the three cities is closely related. Therefore, the Beijing-Tianjin-Shijiazhuang region should collaboratively improve the air quality for common development.Research limitations/implicationsMore approaches may be adopted to calculate the grey correlation degree in the further research studies.Practical implicationsThere exist some practical difficulties in implementing these governance measures.Originality/valueThe paper gives the countermeasures to control the pollution situation in Beijing-Tianjin-Shijiazhuang region.
