摘要
从2008年6月开始,股权分置改革中解禁的非流通股将逐步全流通,这将对流通股价格产生重要影响。非流通股解禁实际上是从不完全市场转向CAPM意义上的完全市场。从有效市场组合角度切入,利用均值—方差平面上的无差异曲线方向的改变进行研究,结果表明:在CARA情形下,非流通股的流通对资产价格水平没有影响;在CRRA≤1的情形下,全流通将导致原有流通市场上的资产价值下降,因此必须给予流通股东以补偿。
From July, 2008, non-marketable shares that have been liberated in the reform of equity separation will gradually become marketable. What impact would this produce on the current marketable shares' prices? This is in fact a transformation from the incomplete market to the complete market as described in CAPM. Therefore, this paper studies the change of directions of Indifference Curve on mean-variance plane in the perspective of efficient market portfolio. The result shows that the marketability of illiquid assets has no effect on liquid assets' prices under the condition of CARA. But Compensation should be paid to the primary holders of marketable shares because the full circulation will reduce the value of primary marketable assets under the condition of CRRA≤ 1.
