城市競爭力（City Competitiveness）是一個城市在全球化發展過程中，與其他城市相較，能更具吸引、更多元化、更快速流動、更具優勢創的創造財富價值的能力。因此，提升城市競爭力，為各國積極推動之目標，除發展地區化、城市治理外，基礎建設的規劃為重要一環。本研究以臺北市、新北市為研究範圍，引用德菲法之專家、學者問卷調查，找出衡量捷運系統持續發展改善的關鍵因素之模型建構，經決策實驗室法及層級程序分析法研究顯示，主要的關鍵因素為經濟與財務規劃、交通與都市規劃、基礎建設與環境、服務與經營能力等四項構面，都市人口密度、地方政府財政自有財源比例等十二項準則。其中四項構面，以經濟與財務規劃構面、服務與經營能力構面為因群，若配合中心度來看，經濟與財務規劃優於服務與經營能力，構面中的準則，以都市人口密度、地方政府財政自有財源比例、都市開發預留捷運系統規劃指標、土地開發規劃與執行能力等四項重要度較高，而評估之重要性較低之準則為大眾運輸使用率、運具間的整合、道路系統、步道系統規劃、系統可靠度等四項，建議朝此項目進行改善與調整。因捷運系統建設與營運，促使人口集中、土地開發、都市規劃，商業活絡，產業發展，快速流動，更具提高城市競爭力的重要基礎建設，也為環境保育提供綠色交通運輸系統，達到科技與自然合一的優勢。
During the progress of globalization, city competitiveness is the ability of a city to outperform other cities in terms of its attractiveness, diversity, pace, and advantageous ability to generate wealth and valuables. In addition to a city’s specialties and its management system, another important factor influencing the competitiveness of a city is its infrastructure（such as its public transit system）. This study identify critical criteria and model for the evaluation of sustainable development of the public transit system -- Mass Rapid Transportation（MRT）-- in Taipei City and New Taipei City via the Delphi Method. The Decision Making Trial and Evaluation Laboratory（DEMATEL）and Analytic Hierarchical Process（AHP）approach identifies four criterias（economic and financial planning, transportation and urban planning, infrastructure and environment, and service and operating abilityand twelve sub-criteria such as city population density and local government’s self-generated capital ratio）. Of the four criteria, economic and financial planning and service and operating ability are the first and second most prominent and influential criteria. Of the twelve sub-criteria, city population density, and local government’s self-generated capital ratio are the three most well-performed factors, while the integration of transportation vehicles, road and trail system planning, and system reliability are the three sub-criteria that require attention and improvements the most in order to achieve a more technologically-advanced yet sustainable metro system for fulfilling the city’s transportation needs thereby making it more competitive.
