過去多數學者探討大股東持股與公司績效的關聯性，並未將股價變化的因素納入考量。倘若大股東持股的增減準則是在於股價變化所產生的，如此其所代表的意義將是有所差異性。因此，本研究以2010年4月至2011年10月之台灣上市公司作為主要研究對象，再以大股東持股變化為標準，取其持股比例漲跌幅最大各100家公司數作為本研究之對象，主要探討大股東持股與股價兩者間之增減變化的四種類型，進而利用統計方法預測未來三個月與一年期間公司經營績效是否有利多或利空的狀況。研究結果顯示:(一) 在未來期間三個月時，不論大股東持股及股價變化如何，對公司經營績效皆無顯著差異性；(二) 在未來期間一年時，當大股東持股減少但是股價卻上漲的情況下，公司經營績效較差。研究結果擬提供投資者對投資標的公司其大股東持股比率變動與股價變化對未來經營期間公司經營績效是否顯著差異性作為投資者投資決策之重要參考依據。

The factor of stock price fluctuation had not been taken into the consideration in the past studies which are researching into the correlation between the large shareholder and company’s performance. If the cause of large shareholder increase or decrease stock holding ratios was on the strength of stock price fluctuation, it would stand for different meaning. Therefore, the main objects of this study are the companies, whose largest shareholder holding fluctuated, and take both of one hundred companies with the largest increase and decrease of the holding ratios, listed on the Taiwan Stock Exchange from April 2010 to October 2011, look into the fluctuation relationship between the large shareholder holding ratios and stock price, and divided research samples into four sigmas and use statistical analysis to predict the company’s performance in the coming three month and one year which are profitable or non-profitable in short term.The results of this study indicate as follows: 1. For the next three months, neither large shareholder holding nor stock price would make notable changes on operating performance. 2. For the coming year, operating performance would go down as the result of lessen large shareholder holding and higher stock price. The result will be taken as substantial information for investors to make decision as they can understand how large shareholder stock hold ratio shifting and stock price fluctuating will impact company’s performance in the future.
