本文研究公司初次採取地區多角化策略投資者給予公司價值的評價。使用Ohlson（1995）提出之會計基礎評價模型為主要迴歸模型進行實證分析。並且區分公司初次地區多角化之投資地區，將投資地區區分為「租稅天堂地區」以及「非租稅天堂地區」，探討初次多角化投資地區不同性質對公司價值之影響。最後探討，當公司將租稅天堂地區之投資視為進入其他地區（如：中國大陸、美國等）的跳板，投資者對於執行跳板策略會有什麼樣的反映。 實證結果表示，公司初次採取地區多角化時，公司價值會有折價之反映且相當顯著。而投資者對於不同地區之投資會給予不同的反映。當公司初次多角化投資租稅天堂時，投資者給予公司較不好的反映，因此使公司價值減損；當公司初次多角化投資非租稅天堂時，投資者給予公司較正向的反映，因此使公司價值溢價。最後公司將租稅天堂視為跳板時，公司價值得到較好的評價。 ;This study, the evaluation for company value from the company Initial International diversification strategy investors give , use Ohlson (1995) basis of accounting evaluation model, proposed as the main empirical regression model analysis.
