A new perspective on a fundamental debate: a multilevel approach to industry, corporate, and business unit effects
用多层次方法重新估计行业、公司和业务单元对绩效的相对重要性，发现业务单元效应最重要，但行业和公司效应也不可忽视，且行业集中度、资源丰裕度和母公司资源环境会影响绩效。
Abstract We utilized a multilevel approach to both estimate the relative importance of industry, corporate, and business segment effects on firm performance, as well as to demonstrate how it enables the investigation of specific strategic factors within each class of effects. Our results confirmed previous findings suggesting that although business segment effects carry the most relative importance, industry and corporate effects are also important. Among the findings regarding specific factors, we found that industry concentration and munificence, as well as the resource environment provided by corporate parents, impact performance. These findings suggest that investigators should consider both industry and corporate environments when examining performance. Copyright © 2006 John Wiley & Sons, Ltd.
