“…In 2006, with the implementation of the China Accounting Standards, derivatives were included in the financial statements for the first time, which made large sample research on derivatives possible in Chinese listed firms. In order to exclude the impact of the financial crisis and the revision of the new round of Chinese accounting standards in 2017, following Zhang et al (2023), we take A-share listed companies from 2010-2016 as the initial sample.
