台灣家族企業的經營績效 / This paper focuses on the performance and characteristics of Taiwan Stock Exchange listed family firms. It shows that the trend between 1997 and 2007 is for more firms to be widely held but that family firms retain their importance as a fraction of total asset. Family firms are found to be on average smaller, older and have a better return on equity than widely held firm. The better performance holds when controlling in a multivariate analysis for firm size, age and China investment. Family firm return on equity is not shown to present the curvilinearity of entrenchment – alignment – entrenchment associated in other studies with increasing levels of control. In a time series analysis from 1997 to 2007, there is no evidence that the better performance of family firms is a temporal effect. The ROA and ROE of family firms is better when controlling for year, asset and debt/asset.
