In rapidly changing environments, firms have to reconfigure to keep align to changes. However, the effect of reconfiguration is mixed and focused on developed economies. Thus, this study examines the effects of the investment business reconfiguration, firm capability, slack resource, ownership structure and firm performance. Secondary data of the 323 firms listed in the Shanghai and Shenzhen Stock Exchanges collected from TEJ database was used to test the hypothesis. From the research results, the relationship between investment business reconfiguration and firm performance is U-shaped. This paper suggests dynamic capability can provide explanations on the relationship between the investment business reconfiguration and firm performance. In addition, the slack resource and ownership structure play a moderating role in the relationship of investment business reconfiguration and firm performance.
