[[abstract]]中文摘要 為增進公共工程的採購效率並達到提升工程品質的目標，本研究針對異質最低標的優點缺點及改善建議進行問卷調查，對象為南高屏地區之公共工程參與人員，期能提供有助於相關作業的意見。收到的有效填答問卷共48份，而其統計分析結果顯示所列項目獲得大部分受訪者的認同，故值得參考。異質最低標的優點中以「可以排除不肖承攬廠商」和「可以減少浪費公帑的問題」最受認同。其缺點中以「評審委員認知有別，很難達一致性及公平性」和「評選浮濫有可能淪為同質最低標決標」最受認同。至於改善建議中則以「評審委員的人數及專業能力應符合工程需求」和「加強採購人員專業訓練」最受認同。本研究並發現很多中小型承攬廠商尚不熟悉此種決標方式。為避免投標廠商家數不足而造成工程延宕，建議業主在招標期間辦理評選說明會，期能提高廠商之參與意願。[[abstract]]Abstract To promote procurement efficiency of public construction projects and achieve the goal of increasing construction quality this study has carried out a questionnaire survey on the pros and cons and improvements of contractor selection based on the lowest bid after technical screening of bidders and aimed at project participants in Tainan Kaohsiung and Pingtung areas in the hope of providing opinions useful for related operations A total of 48 validly filled questionnaire copies were received and the results of statistical analysis of them show that the listed items have largely gained the acceptance of the respondents and hence are worth reference Among the reasons for the selection method “ability to remove unreliable contractors” and “ability to decrease wastes of public funds” are most accepted Among the reasons against this method “difficulty in achieving consistency by screening committee members due to differences in assessment” and “possibility of it being reduced to the traditional low-bid method due to loose screening”are most accepted Among the suggested improvements “number and expertise of the screening committee members to meet the needs of the project” and “professional training of those in charge of procurement” are most accepted The study also found that many medium-small contractors are not yet familiar with this selection method To avoid the delay of a project caused by an insufficient number of bidders it is recommended that owners arrange question-and-answer sessions during the tender period so as to increase the willingness of contractors to participat
