公共工程施工履約爭議處理，存在跨專業知識領域、研究素材取得與方法選擇等高度困難門檻，因此，既往研究鮮少符合統計檢定，多為局部片段敘述性結論，對於具體爭議個案無法一體適用。本研究普查迄至2008年的上一個十年間，台灣高等法院（分院）之公共工程民事訴訟判決，擇取其中凡有一部理由可歸責於採購機關訟案共400件。藉由類目分析、對數線性模型與多元對應分析方法，探索事實審判決相關變數之關聯，並以視覺化輔助數據解析，將超過數百萬言之判決主文，化約成單張二維圖像，並同步指認具備客觀意義之訟案，從而跨越以往直觀取材逕自微觀的研究障礙，填補未能符合科學定義的空白。本研究主要發現如下： 一、 類目分析結合對數線性模型與多元對應分析方法，化繁為簡的邏輯對於治絲益棼的工程法務研究證實具體可行。 二、 工程專業機關較易涉訟，較之於非工程專業機關相對高出51%。採購法施行對縮短訴訟時間具有貢獻，冗長訴訟耗時之勝算比大幅下降近5倍之多；且影響司法實務朝向抑制廠商投機行為，與促進採購機關法律經濟思維發展。 三、 一審判決上訴維持率存有地域上之差異，給付類於北部36.85%，中部24.65%，南部64.94%；賠償類於北部63.15%；中部75.35%；南部35.06%。 The construction dispute is an ancient issue, probably since the time of Hammurabi Code or even earlier. Nowadays, these issues have increasingly been a common social phenomenon in public works, and contribute to a major portion to legal practice. Existing studies regarding public works disputes and claims have drawn on small-scale cases to the exclusion of other cases and few have met the requirements of statistical tests. This study performs an investigation of a total of 400 cases of civil litigation in which owners lost their disputes in Taiwan High Courts and branches between 1999 and 2008. Category analysis coding is used to construct a Log-linear model for judgment decisions; this model is augmented by Multiple Correspondence Analysis to reduce judicial opinions of over 4 million words to a two-dimensional figure, allowing for visual interpretation and identifying specific cases for qualitative examination. The primary findings were: （1）the Government Procurement Law has contribute to shortening litigation times; （2）professional engineering agencies are easily involved in lawsuits, （3）the judgment affirmed of the First Instance review of court houses in different regions are different; （4）the social science methods provide a new channel for construction disputes research.
