AB  - Purpose The 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/approach This study used the grey convex relation model to calculate the grey correlation degree through the AQI of Beijing-Tianjin-Shijiazhuang region.Findings By 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/implications More approaches may be adopted to calculate the grey correlation degree in the further research studies.Practical implications There exist some practical difficulties in implementing these governance measures.Originality/value The paper gives the countermeasures to control the pollution situation in Beijing-Tianjin-Shijiazhuang region.
