加权表决系统在上市公司控制权度量中的应用

The Application of Weighted Voting System in the Measure of the Listed Companies

文章从离散输入的加权表决系统的可靠性理论入手,研究中国上市公司的控制权度量问题.公司的控制权与公司的股权结构有密切的关系.控制权的度量方法有Shapley-Shubik指数和Banzhaf指数模型,和近年提出来的适合中国上市公司的概率股票模型,Shapley-Shubik指数和Banzhaf指数模型没有考虑到股东出席会议的情况,概率投票模型是基于正态分布函数来近似计算的,毕竟这种近似有误差.而文章是基于离散的加权投票系统计算可靠性的方法,建立了中国上市公司控制权的度量模型,并用广义矩生成函数(z变换)的方法计算控制权.

Based on the discrete input weighted system reliability theory,we examin the measure of the Chinese listed companies control.The control of the company has a close relationship with the ownership structure.The measures of the control include Shubik index,Banzhaf Shapley and the probability of voting model.Shapley Shubik and Banzhaf index do not consider whether the shareholders attend the meeting,the probability model is based on normal distribution functions to approximate calculation,but this approximate has a possibility of error. Based on calculating reliability of discrete input weighted voting system we have the method of Chinese listed companies control,and use the generalized moments generating function（z transformation method）to calculate the control.
