基于PIMS数据，通过Chow检验对十种常见权变变量进行重要性排序，发现用户部门（消费或工业）是最关键的权变变量，为研究者和高管提供参考。
This study, based on data from the Profit Impact of Market Strategies (PIMS) program, is a preliminary attempt to prioritize contingency variables for the field of business strategy. Chow tests for structural homogeneity shed light on the relative degrees of overall significance of ten widely-cited contingency variables. User sector, consumer or industrial, was the contingency variable that emerged as most potent among those examined. Implications for researchers and executives are suggested.
