摘要


現金為企業相當重要的財產,但卻是企業所有資產中報酬性最低的,儘管如此,企業仍不將全部的資產拿去投資在報酬性較高的資產,而選擇持有部分的現金,根據本研究之統計,在台灣產業中,又以高科技產業之現金持有量最高,原因為高科技產業之研究發展花費用支出龐大,回收確定,代表著公司可能出現資金不足的情形,所以必須準備一定的現金持有量,因此本論文之目的是採用決策樹方法來預測,台灣上市上櫃之高科技電子業之現金持有,並利用逐步迴歸選出,現金股利發放率、研究費用發展率、槓桿、負債到期結構、來自營運之現金流量、投資活動之現金流量、融資活動之現金流量、營業現金流量比、現金流量比率、公司規模、公司年數共十個變數。並且使用資料探勘軟體WEKA中之決策樹方法(AD Tree、Decision stump、J48、NB Tree、LMT、Random Forest、Random Tree、REP Tree、Simple CART)來進行分類預測,並在研究過程中中共對這八種決策樹設計了三種實驗,分別為:(1) 各決策樹演算法之預測能力;(2) 各決策樹演算法加上效能提升演算法;(3)選一最好之決策樹預測率與Logistic迴歸模型比較。而在這三種實驗中,均顯示隨機森林(Random Forest)為最高,並且也比Logistic迴歸模型之預測率佳。

Cash is very important property for enterprises, but it pays less attention rather than all the assets in the enterprises.The enterprises choose to hold some cash in spite of assets have higher reward after investment. According to the statistics of previous study, especially high-tech electronics industry always has high cash holdings.The high-tech electronics industry spent huge expenses.That means the company may incur the situation of insufficient funds. It is necessary to prepare a certain amount of cash. This paper uses setpwise regression analysis to find suitable variables for cash holdings of high-tech electronics industry in Taiwan. The selected ratios include the cash dividend payout、rate of research costs、leverage、liability、operating cash flow、investment cash flow、financing cash flow、ratio of operating cash flow, ratio of cash flow, size of the company. Using decision tree methods (AD Tree、Decision stump、 J48、NB Tree、LMT、Random Forest、Random Tree、REP Tree、Simple CART) to predict the accurate rate after classification by decision tree methods.This study have three experiments, namely: (1) the predictive ability of the decision tree algorithm; (2) of the decision tree algorithm with performance improvement algorithm; (3) choose the best decision tree forecast rate comparison with the logistic regression model. In three experiments, the Random Forest is the highest and better rate than the prediction of the logistic regression model.
