Abstract This study investigates the temporal and spatial variations of air pollutants in the Guangdong-Hong Kong-Macao Greater Bay Area during 2006-2016 based on the Guangdong-Hong Kong-Macao Pearl River Delta Regional Air Quality Monitoring Network data to identify the key factors affecting the pollutants. The correlation between social-economic factors and the pollutant concentrations is also analyzed using a grey relational analysis. The air quality monitoring results showed that the average annual concentrations of SO2, NO2 and PM10 generally decreased over the study period while the average monthly concentrations had U-shaped curves. However, the average annual O3 concentration increased dramatically with its monthly variations having M-shape curves during each year. The results indicate that industry, energy consumption, population and environmental management are the main factors affecting the air quality in the Greater Bay Area. Thus, the main pathways for improving the air quality in the Greater Bay Area are tough industrial pollution regulations, reduced energy consumption and strengthened vehicle emission control measures.
