The independent and joint effects of the skill and physical bases of relatedness in diversification
研究多元化中关联性的技能基础和物理基础如何独立及联合影响企业绩效，发现单独使用任一基础均无显著效果，但两者结合对绩效有强正向作用。
By examining the independent and joint effects of the skill and physical bases of relatedness, this study develops a multidimensional view of relatedness in diversification. The paper compares the ways the two bases identify relatedness, and examines empirically the relationship between relatedness and performance for a sample of 158 large diversified manufacturing firms. Each base of relatedness alone had no significant effect on financial performance. However, when the two approaches were combined, there was a strong positive effect on most indicators of performance. The findings demonstrate how different bases of relatedness complement and extend one another, and they clarify findings of previous studies that used a single base of relatedness. © 1998 John Wiley & Sons, Ltd.
