From the perspective of organizational identification,employees will advise the organization,both on a high and low level of organizational identification. However,the previous studies did not give a satisfactory explanation for this phenomenon. The paper discussed the relationship change between employee silence and voice behavior at different levels of organizational identification,based on the clearing of each variable' s boundary,and found that the relationship between organizational identification and the behavior of employees is not a simple positive or negative relationship,but is a complicated nonlinear relationship: when the employees have a low level of organizational identification,they have more silence behavior than voice behavior,and with the enhancement of employees' organizational identification,they have more silence behavior and less voice behavior gradually; when the employees are at an ambivalent identification and neutral identification,they have the most silent behavior and least voice behavior; when employees have a relatively high degree of organizational identification,their silence behavior will decrease,and the voice behavior will increase gradually until they have more voice behavior than silence behavior.
