Assessment and redirection of longitudinal analysis demonstration with a study of the diversification and divestiture relationship
回顾了纵向分析在战略管理研究中的应用，通过对203项研究的分析发现多数研究者未检验数据假设或关系稳定性，并以180家财富500强公司为例展示了分析方法对结果的影响。
The authors review the application of longitudinal analysis in strategic management research and show that how such analysis is conducted has implications for empirical results and theory development. A content analysis of 203 longitudinal strategic management studies reveals that most researchers have not (1) tested and controlled for violations in the data assumptions underlying longitudinal analysis or (2) tested the stability and form of the empirical relationships over time. Implications of these findings are demonstrated with analyses of the diversification and divestiture relationships of 180 Fortune 500 companies over the period 1985–88. The results show that empirical results, theoretical development, and practical applications can vary on the basis of how longitudinal analysis is performed. Suggestions for the use of longitudinal analysis in strategic management research are offered. © 1997 by John Wiley & Sons, Ltd.
