As a result, so account for most of china's listing companies. At the beginning of establishing security market, in order to keep the controlling status of public ownership system and being afraid of the lose of statement asset, the stock share of the listing companies are divided into state-owned share, legal person share and negotiable share, among which the former two are not tradable. This leads to the great difference of the stock ownership of listing companies have the following characteristics:(1) complex structure and bad circulate; (2)state-owned shares have little descend (3)the proportion of non-tradable shares decreases slightly;(4)the proportion of legal person shares decreases;(5)the proportion of tradable shares are stable.The separation of stock share ownership affects china's stock market as follows:(1)bad financing;(2)the loss of pricing mechanism;(3)the loss of stock market's function of allocating resources;(4)the macro-economy has close connection with the fluctuation of stock markets, but it is not true for china.Got the approval of state council, on April 29th, 2005, China Securities Regulatory Commission issued the notice on the relevant problems about the trial shares-trade reform.Shares-trade reform will significantly affect the capital market in every aspect.
