Unfortunately, this ignores the diversity among business groups based on their controlling owner.

We argue that their nonfinancial objectives result in diverging levels of diversification and internationalization of business groups across owner types. Specifically, we propose that state-owned and bank-owned business groups have a relatively high level of diversification, labor-owned and mutual-owned business groups have a relatively moderate level, and family-owned business groups have a relatively low level. We also argue that state-owned and labor-owned business groups have a relatively low level of internationalization, family-owned business groups have a relatively moderate level, and mutual-owned and bank-owned business groups have a relatively high level. We add depth to these ideas by proposing that pro-market reforms alter owners' ability to achieve their nonfinancial objectives, leading to diverging changes in business groups' diversification and internationalization across owner types. Specifically, we propose that following pro-market reforms, state-owned and bank-owned business groups experience a large decrease in their level of diversification, labor-owned and mutual-owned business groups see a moderate decrease, and family-owned business groups have a small decrease. We also argue that pro-market reforms lead state-owned and labor-owned business groups to have a small increase in their level of internationalization, family-owned a moderate increase, and mutual-owned and bank-owned to experience a large increase.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Theoretical/Academic Implications</h3>\u0000 \u0000 <p>To the business groups literature, we highlight the importance of controlling owners and their nonfinancial objectives as the drivers of business group diversification and internationalization, complementing the usual focus on market imperfections.
