the reduction of major shareholders in the A stock market
Abstract
The equity pision reform stared from 2005 broke the steady situation of listed companies' holding of tradable shares and non-tradable shares. Because of the reform, listed companies had the right to trade their non-tradable shares in the secondary stock market. With the stock market into full circulation time, to maximize their own profit, shareholders shifted the profit mechanism significantly. While the large shareholder seeking for the profits, they began to focus on the shares' price in the secondary stock market from companies' equity. So, they made use of accounting advantages or information advantages to raise the shares' price in the secondary stock market. Finally, they made profits through reducing holding-shares. In the accomplished studies, scholars mainly take the share reform and the unlocking of the restricted share as the study object. This paper takes the share reduction after the unlocking of the restricted share as the study object to analyze and study the share reduction from the three aspects of share reduction time, market effect and the reasons of the share price falling after the reduction.
Keywords： Large shareholders Share reduction Reduction time Market effect

1.1研究背景及意义
从2005年开始，我国开始进行股权分置改革，它打破了公司流通股与非流通股长期以来分离的局势。非流通股股东需通过向流通股股东支付股改所需的费用之后，才获取了其拥有的非流通股在二级市场上的流通权。
