本研究針對企業赴海外上市決策面的三個構面進行探討並以台商為例，首先是探討企業赴海外上市前的動機為何，其次是企業如何選擇海外上市的地點，最後探討這些企業赴海外上市後的效益，也就是企業在海外上市的前、中、後三個不同階段所可能遭遇到的問題進行實務的探討，並以多重個案分析與類型比對的方式，以及一些台商上市現況的統計數字，希望以過去文獻中曾探討的議題來加以研究。 由於過去的研究偏重於台灣、香港、中國大陸三地市場，為了將層面擴大，特別從台商目前赴海外投資最最多的前十名的國家當中，挑出較為重要的六個國家，分別是香港、中國大陸、新加坡、美國、越南、泰國，並研究當地的已上市台商的現況，從當地上市台商所屬產業家數最多者，挑出具代表性的公司，進行個案研究及比較分析。 從個案研究發現，企業赴海外上市的動機，結果是“有利於開拓海外市場”及“易招募優秀人才”的營運面動機較多；企業海外上市地點的選擇，多半因為“市場流動性及規模及本益比”及“資金運用限制”；至於企業赴海外上市後的效益，結果是“提高公司聲譽”及“有助於產品銷售”另外，並發現香港及大陸上市後股東財富增加顯著。 最後，建議企業未來在選擇海外上市地點時，應多方面考量及評估，並非單純僅就幾個因素就決定企業海外的上市地點，應從各利害關係人的角度，去仔細思考在何處上市將是對企業最有利的。 / The research discusses three perspectives on the decision of enterprise go listing abroad and takes Taiwan enterprise as an example.
