So far, the main influencing factors include the level of economic development (Lin et al, 2014;Xie al, 2016;Jin et al, 2017;Ahmed et al, 2021), environmental regulation Wang and Li, 2021;, industrial structure (Pei et al, 2021;Xue et al, 2021), transport infrastructure (Kinney et al, 2011;Lozhkin et al, 2020;Liu and Dong, 2021), technological progress (Chen et al, 2019;Wu et al, 2020;Ma et al, 2022), financial development (Yang et al, 2021;Yang et al, 2022) and financial capacity (Kuai et al, 2019;Mahmood, 2020;Yang et al, 2022;Yin et al, 2022). Among these factors technological progress is an important means of air pollution abatement, most previous studies have focused on the impact of technological progress on air pollution abatement (Wang et al, 2019;Dong et al, 2020;Amann et al, 2020;Jahanger et al, 2022).…”
