Diversification and Performance: Critical Review and Future Directions*
整合理论框架，回顾了三条研究路径上关于多元化与绩效关系的实证研究，发现各路径结果差异显著，并探讨了关键理论与方法论问题，提出权变视角和未来研究方向。
ABSTRACT This article uses an integrative theoretical framework to review existing empirical research on the diversification‐performance relationship along the three different research streams which have studied this relationship. the article highlights the considerable diversity in the findings across studies in each stream and identifies certain key theoretical and methodological issues which might help to explain the observed diversity. Also discussed is a contingency‐based perspective and several useful directions for future research.
