摘要：
The paper uses pre- and post-periods of marginal securities expansion to examine the impact of lifting the short sales and margin trading ban on stock liquidity. We find a significant increase in stock return following the short selling and margin buying activity. And the results show an improvement in liquidity measurement after the introduction and subsequent expansion of short selling and margin buying. Moreover, the improvement in liquidity measurement is different in different treatment period. A possible explanation for this result is the effect of stock market trend and investor's reluctance to invest in marginal securities.
