Incentive frequency refers to the number of times in a given period of time, which is usually a work-learning cycle for its time units. The relationship between incentive frequency and incentive effect is not simple and direct. Under some special conditions, the two may be inversely proportional. Therefore, only by distinguishing different situations and adopting the corresponding incentive frequency, can the incentive function be played effectively. The choice of incentive frequency is restricted by many objective factors, including the content and nature of the work, the clarity of the task goal, the quality of the incentive object, the status of work and study and the interpersonal relationship, etc. . In general, if the nature of work learning is more complex, the task is more onerous, incentive frequency should be increased, and vice versa. For the goal task more clear, short-term effectiveness of the work, the incentive frequency should be high, conversely, on the contrary. In the specific human resources management, the specific situation should be specific analysis, to take the appropriate incentive frequency.
