Air pollution affects climate change, food production, traffic safety, and human health. In this paper, we analyze the changes in air quality index (AQI) concentrations of six pollutants Jinan during 2014–2021. The results indicate that annual average PM10, PM2.5, NO2, SO2, CO, O3 AQI values all declined year after Compared with 2014, City fell by 27.3% 2021. four seasons 2021 was obviously better than 2014. PM2.5 concentration highest winter lowest summer, while it opposite for concentration. COVID epoch 2020 remarkably lower compared same Nevertheless, post-COVID conspicuously deteriorated Socioeconomic elements were main reasons quality. majorly influenced energy consumption per 10,000-yuan GDP (ECPGDP), SO2 emissions (SDE), NOx (NOE), particulate (PE), PM10. Clean policies played a key role improving Unfavorable meteorological conditions led to heavy weather winter. These could provide scientific reference control City.
