文中利用数理统计手段中的变异系数法，计算交易中心风险投资项目的功效和风险监控指标的权重，并采用功效函数法将各种指标统一为无量纲的单一指标，根据这些指标计算出总的功效函数值的大小，来评价交易中心风险投资项目的功效。案例表明，功效函数法可以直观评价功效和风险的高低。
文中利用數理統計手段中的變異繫數法，計算交易中心風險投資項目的功效和風險鑑控指標的權重，併採用功效函數法將各種指標統一為無量綱的單一指標，根據這些指標計算齣總的功效函數值的大小，來評價交易中心風險投資項目的功效。案例錶明，功效函數法可以直觀評價功效和風險的高低。

The variable coefficient method in mathematical statistics has been introduced to calculate the weight of efficacy and risk of the venture investment project in trading center.The efficacy and risk serve as monitor control indexes and are unified as a single dimensionless index using efficacy function method.According to these indexes,the value of efficacy function can be worked out to evaluate the efficacy of the whole project.It will be demonstrated that the efficacy and risk can be directly appraised by efficacy function in the following cases.
