The Effect of Diversification on Firm Performance in Emerging Markets: Evidence from A-Share Listed Companies in China

Abstract

In recent years, diversification has become a common strategy used by companies in emerging markets. It is believed that diversification operations could help firms get better performance and gain higher profits from a larger internal market. However, contradictory results reveal that diversification empirically hurts firm value and other studies show the relationship between diversification and firm performance is complicated that should be studied in separate industries. The opinion is inconclusive on this topic. This study developed a performance index to see how diversification impact on various perspectives of firm performance. Conclusions as follow. International diversification has a positive correlation with firm performance in several aspects whereas industrial diversification helps firms’ developing ability. However, due to the unavailability of long-term data, we can not rule out the possibility that well-performed firms go for international diversification. Besides, The relationship between diversification and firm performance affected by different industries. The agricultural and natural resource firms tend to exceed manufacturing firms in the efficiency aspects whereas manufacturing companies tend to have advantages in the sustainability aspect compared to service firms. There is also evidence showing that the largest shareholders’ holdings rates have a positive impact on firm performance and state-owned rate has a negative relation with firm performance.
