Abstract: With the increasingly severe issue of carbon emissions, corporate carbon information disclosure can help China achieve “Carbon Peak” and “Carbon Neutrality”. Taking A-share listed companies from 2010 to 2021 as the research sample, Nvivo software was used to comprehensively evaluate carbon information disclosure, which enriched the theoretical framework of corporate carbon information disclosure to a certain extent, and then the fixed-effect regression model was used to analyze the impact of carbon information disclosure on financing costs, as well as the moderating effect of media supervision and the threshold effect of environmental regulation. The results show that there is an “inverted U-shaped” relationship between carbon disclosure and financing costs, and there is a double threshold effect between media supervision and environmental regulation, which has reference value for corporate carbon information disclosure management and financing management.

Key words: carbon information disclosure, financing cost, environmental regulations, media supervision
