2005~2014年期間台灣股市市值低於韓國股市，並面臨國際不斷出現重大金融事件，本研究在探討此期間台灣上市公司之現金流量表中經營、投資和籌資等三大活動各別與總和的現金流量模式對於公司價值的影響。本文使用年份公司資料，並考量變數的縱橫資料特性，採用censored 縱橫資料模型探討上述關係。此研究的結果顯示，投資活動的現金流出與籌資活動的現金流入，有助於公司價值的提升；此亦符合企業追求永續經營時之資本預算決策，需要投資活動的現金流出和籌資活動的現金流入；然而研究期間台灣上市公司經營活動現金流入卻未必顯示正向訊號。本文探討此期間可能影響台灣上市公司經營活動現金流量的特殊經濟背景發現，台灣上市公司有高達15% ~ 24 % 營業活動無現金流入，其中電子產業約占14%~20 %。從本文彙整之資料分析推論，在台灣與韓國國際市場競爭中，台灣企業可能採用利潤率下降防止銷售金額下滑（防止營業活動現金流入減少）或防止市占率下降導致採購減少（防止營業活動現金流出減少）策略，導致此期間公司之營業活動現金流量的提升，不一定提升公司價值。

      This article explores each and the aggregated impacts of the cash flow variables of operating, investing and financing activities on the firm's value from the cash flow statements of Taiwan listed companies during 2005 to 2014 , while Taiwan's stock market value began to be defeated by the Korean’s, as well as that the international financial crisis continued to occur. Since the collected variables are firm-yearly data, this study employes the censored panel data model to explore the above relationship. The results show that cash outflows from investing activities and cash inflows from financing activities contribute to the firm’s value; this is also in line with the capital budgeting policies when the firms pursue sustainable operations requiring cash flows from investing and financing activities. Nonetheless, the results also reveal that cash inflows from operating activities was not necessarily regarded as a positive signal on firms’ value different from the relevant studies, Taiwanese listed companies may adopt a strategy of reducing profit margins to prevent a decline in sales (to avoid a decrease in operating cash inflows) or to prevent a drop in market share leading to reduced procurement (to avoid a decrease in operating cash outflows) from the evidence of that as much as 15% to 24% of Taiwanese listed companies had no cash inflow from operating activities with the electronic industry accounting for approximately 14% to 20%. As a result, the operating cash inflow during this period may not enhance the firm’s value. Based on the data analysis of this study, it can be inferred that in the international market competition between Taiwan and Korea during this period, Taiwanese companies may adopt strategies of reducing profit margins to prevent a decline in sales (to prevent a decrease in cash inflows from operating activities) or to prevent a decline in market share leading to reduced procurement (to prevent a decrease in cash outflows from operating activities). This led to the result that cash inflows of operating activities during this period did not necessarily enhance the firm’ s value.
