光電產業為一成長力高之產業,在2007年本國總產值已占全球市場約17%,對於本國經濟成長有相當之貢獻。本研究試圖探討資本密集度高之光電產業之自由現金流量,自由現金流量時常被當作衡量企業價值之工具,但其影響因素與如何影響企業價值之相關文獻甚少,因此本研究希望能夠找出在企業中自由現金流量所扮演之角色與其明確之影響因素。又因光電產業處於成長階段,規模與成長率對於自由現金流量與企業價值均十分重要,故本研究將成長率放入影響因素中進行探討,其他影響因素包含信用評等、專利授權等也將一併探討。本研究將會就自由現金流量、影響因素與企業價值三者間之關係分析。實證部份採用經濟新報資料庫之資料,以上市櫃公司五年之年資料為基礎,利用近似不相關迴歸模型(SUR)進行實證。 實證結果發現,在不同企業規模下,自由現金流量有顯著之不同,企業規模越大,企業之自由現金流量反而越少。同時,自由現金流量對於企業價值之影響主要表現在未來期間,顯示自由現金流量對企業價值具遞延效果。另外,也發現自由現金流量之介入,會使影響因素對企業價值之顯著性降低,顯示自由現金流量在影響因素與企業價值間擁有部分中介效果。
The optoelectronics industry with the impressive ratio of growth, the total output from Taiwan has reach 17% at 2007. It is a great contribution to the growth of economy in Taiwan.
