提升營運量是高雄捷運永續經營之迫切課題。本研究以德菲法在公共政策、經營管理、乘客感受等3 個 構面中，篩檢出提升高雄捷運營運量之9 項重要因素，再利用層級分析法及社會判斷理論評估各構面與因素 間之相對權重與函數形式。在4 組受測群體分別操作AHP 與SJT 所獲得的構面權重中，除政府官員在AHP 組的權重呈現公共政策略重於經營管理外，其餘各組受測者均最重視乘客感受，其次是經營管理，最後才是 公共政策。另外，各受測群體對乘客感受及經營管理兩者與提升運量間的函數形式，均以正相關的比例為最 高。而公共政策與提升運量間的函數形式卻以負相關或適中最好的比例最高，顯示多數受測者認為政府的過 度介入未必有利於運量提升。

From the beginning of opening, KMRT is suffering from the loss. It has become an urgent issue to improve the performance. This study used Delphi to select nine important decision-making factors about promoting KMRT’s performances in three dimensions−public policy, management, and affection of passengers. Then this study applied analytic hierarchy process (AHP) and social judgment theory (SJT) to get the weights and the function forms for dimensions and factors analysis. AHP and SJT test were applied in four stakeholder groups separately. All groups agree the ranking of weights is affection of passengers, management, and public policy except officers in AHP test, who attach a lightly higher weight to public policy than management. Besides, for all stakeholder groups the highest proportion of function form between management, affection of passengers and KMRT’s performances are positive linear. But the highest proportion of function forms between public policy and performances are negative or inverted U-shaped quadratic. It shows that most of the subjects don’t think the involvement of public policy will improve performance.
