Note—Developing a Global Diversification Measure
针对现有衡量方法只关注国际市场或产品维度的问题，本文构建了一个同时捕捉两个维度的全球多元化衡量指标，帮助商业战略研究者分析企业的全球多元化策略。
Previous measures, focusing on either the international market or product dimension of corporate diversification, have been unsatisfactory for analyzing global diversification since both dimensions constitute important elements of a firm's global diversification strategy. This study constructs a measure in which both dimensions can be captured, allowing business strategy researchers to examine corporate diversification in the global context. In accomplishing this task, this study extends the Jacquemin-Berry entropy diversification measure to the global horizon.
