Diversification in context: a cross‐national and cross‐temporal extension
研究了法国、德国和英国在1982-84和1992-94两个时期多元化与绩效关系的稳定性，发现总体支持相关约束多元化，但不同国家和时期存在显著差异。
Abstract This research note examines the stability of diversification performance relationships in three countries (France, Germany and the United Kingdom), for two time periods (1982–84 and 1992–94). The aggregate findings, taking the three countries and two time periods together, support a general model favoring related‐constrained diversification. However, disaggregated analyses show sharp variations in different countries and time periods. The note concludes that although broad performance relationships can be found, these can be expressed very differently in particular contexts. We consider implications for further research.
