Based on the theory of high-level echelons, this article selects A-share listed chemical companies from 2017 to 2020 as samples to examine the relationship between the characteristics of senior management teams in chemical companies and corporate performance, as well as the moderating effect of corporate environmental information disclosure. The research results indicate that there is a significant negative correlation between the average tenure of senior management teams in chemical enterprises, the proportion of female executives, and corporate performance. The disclosure of environmental information in chemical enterprises significantly weakens the negative correlation between executive team characteristics and corporate performance.
