A dynamic game model on the action strategies between venture entrepreneur and venture capitalist is built.Based on the model,an analysis on the incentive mechanism for the venture entrepreneur,monitor mechanism of the venture capitalist and correlation is made.It is concluded that from the aspect of the venture entrepreneur,the monitor mechanism and the incentive contract is complement;but from the aspect of the venture capitalist,the monitor mechanism and the incentive contract is alternative.Then combining with the parameter analysis,the variable factors between the best incentive strength and the generalized monitor strength is researched.
