PIMS and the FTC line‐of‐business data: A comparison
比较PIMS和FTC行业数据库在描述性和关系性结果上的一致性，发现两者高度可比，差异源于特殊原因而非系统性缺陷，对产业组织和商业战略研究者有参考价值。
Abstract The PIMS data base and the FTC Line‐of‐business data base have both been widely used in industrial organization research and business strategy research. However, both data bases have been criticized because of their sample compositions, their measurement methodologies, and the underlying data structures. This study was designed to explore the issues that have been raised about the two data sets by comparing findings produced by them. Since criticism of the two data sets are dissimilar, it is highly unlikely that comparable results would be obtained if the quality of either or both data sets was deficient. This study shows that the data sets generally produce highly comparable descriptive and relational results. However, a number of disagreements do arise, and these are traced to idiosyncratic causes, rather than to the kinds of systematic shortcomings suggested by critics.
