台灣高鐵面臨財務上的困難，其主要的原因為負債比例偏高，從台灣高鐵2007年1月至2010年6月，營運以來的經營資料，可知台灣高鐵現在利息負擔沉重，短時間內，台灣高鐵的財務，無法達到損益兩平。經對於台灣高鐵每月的收入、支出的分析，證明本研究以發行特別股的方式，不只可降低台灣高鐵的負債，也可使貸款給台灣高鐵的銀行，其手中持有台灣高鐵的特別股，在台灣高鐵股價優於預期時，銀行可將手中的台灣高鐵特別股，轉為普通股的方式出售，由一般投資人取得普通股；反之，如果股價不如預期，銀行可持續持有台灣高鐵的特別股，無損於銀行所擁有的債權。

The Taiwan High Speed Rail Corporation (THSR) has faced the difficulty of finance. The main reason is that the debt ratio of THSR is getting higher and higher. We can learn from the operation data, January 2007 to May 2010 from the THSR that the interest encumbrance is heavily now. The finance of THSR will not reach balanced in a very short time. Through the research of monthly income and expenditure from THSR, we can prove that with the release of preferred stock not only can lower the debt of THSR, but also can let those banks that lend money to THSR can hold the preferred stock. When the stock price of THSR is better than expectation, the banks can change the preferred stock into the common stock and sell the common stock to general investors. On the other hand, if the stock price is worse than expectation, the banks keep the preferred stock from THSR. This will not harm the rights of creditor of the banks.
