摘要股权分置改革从2005年开始实行，它打破了长期以来上市公司流通股与非流通股相分割的局面。股权分置改革后，我国上市公司原有的非流通股获得在二级市场上流通的权利。随着股票市场进入全流通时代，上市公司股东以自身利益最大化为目标的获利机制明显发生转变。他们从关注公司净资产转向更加关注二级市场股票价格的变化。大股东会利用自身的各种优势，包括财务优势、信息优势等，尽量地抬高股价，获取投机收益。在全流通时代，大股东在二级市场上实现利益的最终方式是减持股份。本文从大股东减持的时机选择、减持市场反应和减持后股价变动影响三个方面进行深入的分析和研究。26375

Title The timing,market reaction and influence factors of
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
