In a recent research, Cheng & Chen (2004) found that authoritarian, benevolent, moral, and regulatory leadership were the four types of leadership behavior adopted by Taiwanese expatriate managers. As a follow-up of the above research, this research discusses how these leadership behaviors develop and shift, and what are the factors for these changes? This research collected data through semi-structured interviews. The researchers interviewed 27 Taiwanese expatriate managers at Kunshan, Suzhou, Shenzen, Dongguan, and Guangzhou, and then conducted inductive analysis and contextual analysis to generate results for the research questions. The results indicate that Taiwanese expatriate managers in Mainland China mainly showed two particular patterns of changes in the practice of leadership styles: "from authoritarian to benevolent" and "from benevolent to authoritarian". The research also found that the manager's perception of the subordinate (with respect to guanxi, loyalty, competency, hardworking, utilitarian, honesty, etc.) is the main reason for the changes of leadership style. The researchers compare the results of this study with literatures on western contingency leadership, Chinese differential leadership, and cross-cultural leadership. In addition, this research discusses the possible impact of Mainland China's culture toward leadership behaviors.
