The origin of the fund - management stimulating problem is that the standard of rational agent ’ s activities is utility maximum . but , in the reality , the fund investor and the fund administrator are a kind of consignation and there is information asymmetry . the fund investor ( principle ) wants to make the fund administrator ( agent ) act according to the benefits of the former , but the investor ca n ' t observe the investment activity of the administrator directly and in time . he can only observe other variables which are decided by the administrator ’ s activity and other outside uncertain factors 基金激励问题产生的根源在于理性人的行动都以自身效用或利益最大化为标准,但在现实中,基金投资者与基金管理者是一种委托代理关系且两者之间存在着信息不对称,基金投资者(委托人)想使基金管理人(代理人)按照前者的利益选择行动,但投资者不能直接及时地观察管理人的投资行动,他能观察到的只是另一些指标变量,这些变量由管理人的行动和其他外生随机因素共同决定。
Due to the existing volatility , stochastic and dynamic properties of cash flow , this paper employs exponential smoothing method and moving average method to eliminate the effects of the stochastic factors , use the seasonal exponent to eliminate the seasonal volatility of the cash flow , the exponent curve and polynomial fitting curve to estimate the overall cash flow and also provides the calculating methods and identifying principle of the overall cash flow 由于现金流量的波动性、随机性、动态性等特性的存在，依靠单一方法无法科学、准确的预测现金流量。论文提出利用指数平滑和移动平滑的方法来剔除随机因素影响，利用季节指数来消除现金流量的季节波动，之后再利用指数曲线或者多项式拟合曲线来预测整体现金流量的方法，并给出了整体现金流量的计算方法和确定原理。
