Abstract: This paper begins from a paradox on ID's independence and recompense.It makes research into its academic root.It points out that admitting the incomplete independence of ID's independence is the starting point of the recompense design in the case of failure to establish the credit mechanism within a short period.We must adopt recompense-stimulating mode combining long term with short term.The key of recompense design is to grasp the balance of economic interest and independence.In practice we also should keep the clarity of operation.
