我国证券投资基金快速发展，从属于同一家基金管理公司的单个基金越来越多，形成基金家族。本文研究从单个基金和基金家族的整体两个层面，采用实证检验方法对其业绩持续性进行研究，研究表明我国开放式基金仅具有短期的业绩持续性，而基金家族的整体业绩不存在持续性，籍此结果提示投资者不应仅仅关注基金的短期业绩，应更多关注基金的长期业绩表现，规避投资中对家族和规模的偏好，关注高价值基金，才能最大程度保障资金安全和自身的利益。%With the rapid development of China's securities investment funds, there are more and more single funds subordinate to a same fund management company, forming the fund family. This paper studies the performance persistence of the single fund and fund families by using empirical testing methods. The research indicates that China's open-end fund has only a short-term performance persistence, and the overall performance of the fund family do not have performance persistence. The results suggest that investors should not only concern the short-term performance of the fund, should pay more attention to long-term performance of the fund to avoid the preference for family and size in investment and focus on high value fund, so as order to maximize the safety and interests of funds.
