Abstract It is difficult to exam whether the employees¡¦ perceiption of political behavior in an organization has negative influence on their extra-role behavior. However, facing such difficulties, many researches in management field are still interested in investigating organiztional political behavior. Previous studies found that when employees perceive organizational political behavior, their trust towards orgnizations would decreased and their organizational citizen behavior (OCB) would be lessen. Even though at certain degree, OCB is not significantly related to the formal work assignments and performance evaluation, OCB is not only essential to contexual performance, but also influential to self efficacy and work efficiency. This study aims to explore the difference of employees¡¦ perception of organizational political and OCB in different organization types of international business and local companies in Taiwan. It is also to investigate whether the management styles in international business and in Taiwanese companies would have different impact on employees¡¦ perception of political behavior, and cause different OCB. The research results indicate that first of all, in both international and local Taiwanese companies, management styles have influence on OCB, while the democratic leadership is more effective than the paternalistic leadership. It is also found that political behavior in organizations has impact on OCB, while the organizations without political behaviors have better performance. Secondly, in the international companies, the management styles have significant interaction effect on political behaviors in organizations and OCB; under the democratic leadership, there is less political behaviors and therefore has more effective OCB. Lastly, in the local companies, the management styles have significant interaction effect on political behaviors in organizations and OCB; under the democratic leadership, the less political behaviors does not lead to effective OCB. keywords¡Gmanagement styles, organizational citizen behavior (OCB), Organizational Politics Perceptions, paternalistic leadership, democratic leadership
