“…(2019), Qing (2020), Dang (2021) , Hu (2022) have applied the Oaxaca-Blinder decomposition procedure to study income inequality under gender differences, while Xie and Yao (2006), Liu (2021) have combined the Oaxaca-Blinder decomposition and the Cotton decomposition to carry out research in this field; Meng and Zhang (2001), Li and Ma (2006) have adopted the Brown decomposition to study the impact of the occupational segmentation on the income inequality; Ge (2007) and Zhang (2020) have used the Applenton decomposition to study the extent to which sector choice can affect the gender income gap; Yao and Li (2007) have used the Mincer income model to study changes in the income inequality in unified groups; Chen and Duan (2009), Hua (2018), Ding (2021) have applied the MM decomposition to study the gender income distribution gap. Additionally, , , Fang (2020) have adopted the FFL decomposition (Firpo 2009) to study the income inequality.…”
