摘要: 从上市公司披露内部控制一般缺陷的自愿性动机出发,构建了不完全信息条件下公司内部控制一般缺陷披露问题的信号博弈模型,给出了自愿披露内部控制一般缺陷的混同均衡和分离均衡条件;同时对2011年沪深两市上市公司内部控制一般缺陷的披露情况进行了描述性统计,研究结果表明:剔除ST类公司,披露内部控制一般缺陷公司的绩效要好于行业均值。由于现存规章制度中的惩罚机制不够完善,因此对于内部控制一般缺陷的披露现状,市场上更多的是混同均衡,分离均衡尚未实现。

关键词: 内部控制, 信息披露, 自愿披露, 信号博弈

Abstract: Using the 2010—2011 data of Shanghai Securities Exchange A Shares, this paper made an empirical analysis on the relationship of institutional ownership, analysts follow-up and stock volatility by constructing a non-linear simultaneous equation model. It was found that institutional ownership increases the volatility of the stock market, and the proportion of stock market volatility and institutional ownership takes on a nonlinear inverted U-shaped relationship; securities analysts follow-up plays an important role in stabilizing the stock market while the stocks of much volatility could still attract analysts to follow; there exists a positive correlation between institutional ownership and analysts follow-up; analysts and institutional investors are more concerned about the short-term interests while ignoring the long-term interests. This study is of great significance in regulating and managing institutional investors and securities analysts as well as educating analysts and investors.

Key words: information investor, institutional investor, securities analyst, stock volatility
