Supervised by Prof. Hanxiao Wang (CAU), Prof. Chunding Li (CAU), Sep. 2021 – Jun. 2022

• China Agricultural University's Best 100 Undergraduate Thesis Award (College ranking: top 1% of 200+ students; grade: A+). 

• Main achievements: Conducted DiD for analyzing impact of PFTZ establishment on enterprise ESG performance, analyzed time variation of the effect through propensity score matching (PSM) method, found the establishment of PFTZ could improve the ESG performance of enterprises by improving their environment scores in ESG, but the effects on improving enterprise' social responsibility scores and governance scores are limited.
