Abstract:

To reval the disparities and shortcomings in safety and emergency management information disclosure, and to promote the strengthening of corporate safety responsibility and to improve of emergency management capability, textual information from 1 593 listed companies from 2008 to 2023 was collected from multiple sources, including CSR and annual reports of high-risk industries. Based on the three dimensions of reliability, relevance, and quantification, TF-IDF weighting method was applied to construct a 12-indicator evaluation framework for the quality of safety and emergency management information disclosure. The results show that corporate social responsibility reports provide more comprehensive safety emergency information and have become the primary disclosure channel. The overall quality of disclosure is relatively low. Only a few companies score in the upper range for disclosure quality, and the gaps between compaies are significant and continuously widenning. The disclosure content gradually focuses on the construction of emergency plans, emergency response and risk prevention and control strategies, but quantitative disclosure in areas such as safety investment and regulatory compliance remains insufficient. Significant differences exist among industries in terms of the number of companies disclosing information, focal points of disclosure and disclosure quality, with a lack of unified standards.
