The system of price limits the Stock Markets use of price stabilization measures. This is the starting point of the Topics in this article the operation mechanism of the system of price limits is important for policy makers and investors, but academia on the practical effect of price limits, but there is a fierce debate. System of price limits from the three aspects of validity, volatility, liquidity of the empirical analysis of the system, aimed at the analysis system of price limits on China's stock market, in order to examine the effect of this system for securities regulatory authorities to provide a basis for policy formulation, to promote the development of the stock market. Paper uses event study and packet combining empirical analysis of the interference effect of the delayed effects of the spillover effects of volatility and liquidity, from a statistical point of view to analyze the effects of the operation of the system of price limits; use of the system of price limits may lead to price discovery Correlation Analysis Method Change to stop the relationship between the frequency of the equity scale, from another point of view to analyze the system of price limits on stock market volatility; the constructed regression analysis different scale stock reaches Change stop at the two-day, The turnover rate of change in three days, the research system of price limits for the different sizes stock liquidity.

Research and analysis by comparing concluded between the equity scale and frequency of limit moves a significant negative linear relationship. The study results will provide regulatory agencies classified amplitude provide a theoretical basis for adjusting the price limits. The results of the regression analysis, Change stop after a day of massive stock turnover did not significantly change in trend, the day after the daily limit of the small-scale stock turnover significantly increasing trend, indicating that the system of price limits of different sizes have different effects on stock liquidity.
