Clearing out zombie firms is a critical challenge for both developed and developing countries. This article draws upon data from Chinese listed SOEs to examine the impact of mixed-ownership reform on zombie firms. The findings indicate that non-state-owned shareholders participating in mixed-ownership reform by appointing directors can help reduce the possibility of SOEs becoming zombie firms, while participating in mixed-ownership reform through shareholding is not significant. Moreover, the impact of mixed-ownership reform on zombie firms is more pronounced for firms in competitive industries and firms located in the eastern region of China. Mechanism analysis reveals that the reduction of inefficient investment has a positive mediating effect between mixed-ownership reform and zombie firms.
