影響工程標價之因素眾多，而標案規模為其中最重要因素之一，然而因為缺少實際數據，過去鮮少有研究以實際案例分析予以佐證。本研究藉由蒐集國內第二高速公路25個以「支撐先進工法」與23個以「場撐工法」施工的工程案例，以多元迴歸分析探討標案規模對工程標價的影響。
本研究首先透過專家訪談以及文獻回顧，確定出橋樑工程之規模因子，分有「橋樑全長」、「橋樑總面積」及「橋樑跨徑」等三項，另加上足以反應市場競爭情況之「競標廠商家數」，共計四項因子當作自變數，再以橋樑工程上部結構之合約單價為依變數進行探討。本研究經過迴歸係數判定﹙R2﹚、t檢定、F總檢定量檢測及共線性檢定，建立出「支撐先進工法」與「場撐工法」之迴歸模型，並依之推論出工程標案規模的大型化，可降低工程標價，而且競標家數的多寡，對於工程標價亦有顯著的影響。

Many factors that affect the bid price level have been identified previously and among these, project scale is recognized as one of the most important factors. However, few empirical studies have been made due to lack of study samples. This research is designed to study the effect of project scale on the bid price. Conclusions were made based on the multiple regression analysis of data collected from 25 projects adopting “Advanced Shoring Construction Method” and 23 projects adopting “Scaffolding Construction Method” of Taiwan Second Freeway.
Through literature reviews and interviews with experts, three independent variables that represent project scale such as “length of bridge”, “span of bridge”, and “total deck area of bridge” were selected. “Bidder number” which represents the competition level of market situation was further considered as the fourth independent variable in the multiple regression analysis. The bid price of bridge upper structure was used as dependent variable. A model was established according to the statistical results and it appears that the level of the bid price is highly associated with the project scale and the number of bidders.
