An incentive model is quantitatively constructed to evaluate bank’s branches efficiency via compensating periodic bonus. A panel data approach is applied for a bank over 9 months in 1393. The null hypothesis is experimentally defined based on the average bonus equality in different branches. Results indicate that the bonus average, deviation and the other moments have equally-disincentivly caused a contraction in the efficiency and future profitability.  Meanwhile, the bank was obviously failed to translate the efficiency and risk management requirements into the bonus compensation. The incomplete-efficiency scenario is also observed in the four different bonus compensation mechanisms so incentive indicators have not been influenced by the financial and performance variables.
