Our initial sample consists of all Chinese manufacturing firms listed on the Shanghai and Shenzhen stock exchanges between 2012 and 2021.We collected firm-level financial data from the China Stock Market and Accounting Research (CSMAR) database, a key source for information on Chinese public-listed firms. Data on green patents and patent pledges were sourced from the China National Intellectual Property Administration (CNIPA), the official government authority on intellectual property in China. Additionally, media data were obtained from the Wise News database, which covers a wide range of media sources in mainland China. After removing observations with missing data, our final sample contained 3,011 unique firms and 20,582 firm-year observations.
