In this study I investigate the organizational mechanisms (pathways) through which strategic investors can help a firm improve performance. Many commercial banks in China have recently invited foreign banks as strategic investors since China’s entry into the World Trade Organization (WTO), hoping to gain managerial and technological knowhow from the foreign banks. Using Shanghai Pudong Development Bank as a representative example, I conduct an in-depth qualitative analysis about how the joining of Citi Bank as a strategic investor has helped the local Chinese bank improve its financial performance. On the basis of a comprehensive review of the relevant literature, I first develop a theoretical model that describes the organizational mechanisms (pathways) through which foreign strategic investors can influence the local bank’s performance. Specifically, by participation in corporate governance, the foreign strategic investor can have a positive influence over the local bank’s strategy development, operational targets, incentive systems, and organizational culture, which consequently lead to improvements in the local banks operations and financial performance. I then use a case study method to substantiate the logic and the pathways of the model with the detailed information collected from the Shanghai Pudong Development Bank and Citi Bank strategic alliance. The results are consistent with the model’s descriptive validity.
