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 wants to make the fund administrator act according to the benefits of the former, but the investor can'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，基金投资者想使基金管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。

The critical level of asymmetry is strongly dependent on the entry tension.

Then positively ana.lyzed transmission effect of monetary policy of China in recent years, and with relative theories, discussed rr~ore deeply the existing principal problems on transmission mechanisms of monetary policy in our state under the realistic institutional situation of economy and finance:(1)Monetary policy tools lag behind the economic and financil background;(2)Separated and uneven money markets, the lack of transaction agents and defect in the relation between money markets and c~potal markets, have rendered the transaction of monetary policy lack on effective channel;(3)over-speculating, illegal operation and insufficient competition have severely weakened the transmission fumction;(4) systematic defect of state -owned commercial bank, asymmetry between financial and economic composition have made monetary policy lose an effective carrier;(5) factors beyond the financial system, such as soft cornstraint over state - owned enterprises policy decision, imperfect social insurance system, etc.

接下来对我国近年来的货币政策传导效果进行了实证分析，在此基础上运用相关传导机制理论并结合我国实际经济、金融制度与环境论述了我国当前货币政策传导机制的主要问题：（1）货币政策工具相对于经济、金融环境显得落后；（2）货币市场的分割、不平衡、交易主体不全以及货币市场与资本市场的联系机制缺位使得货币政策缺乏一个有效的场所；（3）资本市场特别是股票市场的过渡投机、违规操作以及不充分竞争严重地削弱了证券市场的传导功能；（4）国有商业银行现行体制的缺陷，金融结构与经济结构的非对称使得货币政策传导受阻；(5)金融体系外的因素（如国企决策行为软约束、社会保障制度不健全）。
