Based on the proxy theory, information asymmetry theory and signal transmission theory, this paper empirically tests the impact of executive changes on goodwill impairment. It uses the data of A-share listed companies in Shanghai and Shenzhen stock exchanges from 2010-2018 as samples. The research results show that: 1) Compared with companies that have not undergone executive changes, companies that have undergone executive changes have a greater degree of goodwill impairment; 2) The positive correlation between executive changes and goodwill impairment is only manifested in the companies audited by “non-Big Four”, which implies that high audit quality can effectively play an external monitoring role and curb the opportunistic behavior of senior management.
