Does corporate strategy matter?
反驳了公司战略不重要的观点，通过分析方差分解文献，证明公司层面的因素，特别是公司战略，对业务间盈利能力差异有显著贡献。
A revisionist view that corporate strategy does not matter has gained considerable influence in recent years. This view largely stems from empirical results of early variance decomposition studies that found negligible corporate effects associated with profitability differences between businesses. Our analysis of the variance decomposition literature shows this view to be incorrect. Not only do the studies as a group show that factors at the corporate level of organizations contribute to profitability differences, but also evidence suggests that factors specifically associated with corporate strategy contribute to corporate effects. Corporate strategy in fact does matter. Copyright © 2001 John Wiley & Sons, Ltd.
