This paper analyses the homogenous tendency of open-end fund at first,pointing out that unperfect development of market and investors' immature investment opinions is the origin of such phenomena. Secondly,having compared the fund sizes and purchase fee rates of 25 open-end funds in China,conclude that there are problems of diseconomy of scale and indistinctive relativity between fees and achievement in Chinese open-end funds. Then this paper introduces benefit and cost function to analyze the problem of lack of motivation and constrain mechanism towards fund managers because of unreasonable fees in China. Thirdly,this paper analyze funds managers' normal hazards by static game model,and then points out fund managers have serious tunneling behaviors in Chinese open-end fund industry. In the end,this paper analyzes the causes of liquidity risk of open-end fun and the particularity of liquidity risk of open-end fund in China,and concludes that liquidity risk in Chinese open-end fund industry is higher through calculating the rates of share change and comparing the portfolio selections of top 20 open-end funds in China.

本文首先分析了我国目前存在的基金产品同质化现象，指出市场发展的不完善以及投资者投资理念的不成熟是同质化的根源所在；其次对比了我国现有的25只开放式基金的规模和申购费率，得出了我国开放式基金存在着规模效应不明显以及基金业绩与费率相关性不强的问题，并引入效益函数和成本函数分析了由于我国开放式基金费率不合理引发的基金管理者激励约束机制缺失的问题；再次，应用静态博弈模型分析了基金管理人面临的道德风险，指出目前我国开放式基金由于监管机制脆弱而存在着较为严重的管理者利益输送行为；最后，分析了开放式基金流动性风险的形成原因以及我国基金市场流动性风险的特殊性，并通过计算目前我国基金资产规模前20位的开放式基金的份额变动率以及比较它们的投资组合结构，得出了目前我国开放式基金流动性风险偏大的结论。
