Abstract: | We examine the effect of ownership structure on firm performance, for firms listed on Vietnamese stock exchanges, using 2744 firm‐year observations over the period from 2007 to 2012. We find a non‐linear relationship between ownership structure and firm performance. State ownership has a convex relationship with firm performance. This paper finds that firm performance increases beyond 28.67 percent level of state ownership. Foreign ownership has a concave relationship with firm performance. We find that firm performance increases with an increase of foreign ownership up to a level of 43 percent and then decreases. Policy makers should encourage foreign ownership and widely dispersed state ownership in firms, which can help improve firm performance. |
