二手車的價格，取決於很多因素，如年份、車身鈑金、內裝、行駛里程、車型、汽車製造商和其他條件，本研究利用台灣二手車拍賣市場資料來探討二手車價格的決定因素，本研究聚焦於國產二手車，其最終拍賣價格不超過一百萬新台幣，本研究不含卡車、進口車和豪華車，研究數據來自2014年台灣二手車拍賣網站。
本研究以線性模式與最小平方法來評估這些數據。研究結果顯示，所有選擇變數之p-value介於1％的信賴區間（p值<0.01），證明所選擇之變數(引擎狀況、使用年份、行駛里程、車身鈑金、內裝車型、與豐田汽車製造商變數)與二手車價具有顯著相關。但交易日在星期五與引擎數2千CC以上之變數之p-value為0.1217，不具有車輛的價格顯著相關性。

Price of the second-hand car depends on many factors, such as age, conditions of body and interior, mileage, type, manufacturer and many others. This research examines determinants of second-hand vehicle price using the example of Taiwan auctions. The research focuses on used passenger cars which were produced in Taiwan and whose final price does not exceed one million New Taiwan Dollars. Trucks, imported cars and luxury vehicles were excluded from the research. The study uses data from used cars auction website which included observations of successful transactions in 2014. The log-linear multiple regression model is applied to evaluate this data. According to the results, polynomial log-linear multiple regression model is more suitable for this research and produces better results. As the result shows, all chosen variables are statistically significant at 1% confidence interval (p-value<0.01) and all coefficient signs are as expected. Only one variable LOG(MILEAGE) is not statistically significant.
