摘  要
 自2000年9月以来，华安创新、南方稳健成长以及华厦成长开放式基金相继推出，我国基金业进入了一个新的发展时期。伴随着中国经济的高速增长，中国股市的狂热，开放式基金成了目前国内的一个投资热点之一。基金资产净值是投资者可以得到的关于基金资产实际价值的主要公开信息，而且投资者通常都将基金资产净值视为基金资产的实际价值，因此应将尽可能地真实反映基金资产实际价值作为计算基金资产净值时选择证券价格的主要原则。基金资产净值估算是开放式基金有效运作中最关键的一环，在目前所投资的某些基金品种价格缺失的情况下，还不可能有较完善的解决方案，但是随着估值行为本身不断的完善，这一解决方案不断地接近合理。
 我国目前普遍选取基金投资的证券当日交易均价计算基金净值，采用此计算方法的主要优点是：与收盘价相比，证券的当日交易均价比较难以操纵，因此采用此方法计算出的基金资产净值也不容易被操纵，更能合理地反映基金资产的实际价值。在基金业发展初期，我国各基金都选取股票和债券的当日收盘价作为基金资产估值价格，计算基金净值。

Abstract
 Since September 2000, open-end funds, like Huaan Innovation, South Robust Growth and Edifices Growth, have been launched, so China''s fund industry has entered a new period of development. Along with China''s fast economic growth and China''s stock market boom，open-end funds become a hot one in domestic investment market.  Net asset value of fund is the  major public information of the actual value of funds that investors can get, and investors usually regard net value of fund as the real value of fund , net value of fund which should be possible to truly reflect the real value of fund is regarded as the main principles in choosing securities prices. Estimation of net value of fund is a key ring of the most effective operation on open-end funds, at the absent of prices of some securities invested, there can be no better solution in the present conditions. The introduction and improvement of the solutions should keep becoming reasonable as the valuation itself.
 At present in China, it is generally to use the day trading average price of securities investment fund to calculate the net value of the Fund, The major advantages of this method contains: Compared with the closing quotation price, day average price of the securities trading is more difficult to manipulate. Therefore, the net value of the Fund calculated using this method is not easy to be manipulated, and reflect the real value of assets of the Fund more reasonable. In the early days when the fund industry first developed, Funds in China all treated the closing quotation price of stocks and bonds to be the Fund''s assets, then valuated the prices and calculated the net value of Fund.
