都市及區域交通隨著經濟發展與私有機動車輛的迅速成長，擁擠情況日益嚴重，運輸部門的能源消耗與二氧化碳排放量亦日益升高。客運業者正面臨外在節能減碳要求、同業競爭、成本提升與內在營運艱困雙重壓力，導致客運業者服務品質下降，長期營運面臨虧損。本研究依產業特性評估項目考慮負面因子，以Fielding et al.(1985)之績效評估架構，從成本效率及服務效果面探討客運業者路線經營效率變化趨勢及改善方向，以提升客運業者服務水準之品質，並獲得永續經營。 本研究根據Avkiran & Rowands (2008) 所提出Slacks-based Measure-Data Envelopment Analysis(SBM-DEA)三階段包絡分析模式進行實證分析，藉由運輸產業績效的探討，排除外在環境變數及統計干擾等因素，以較客觀方式找出經營績效較佳路線，輔以麥式生產指數，進行路線經營績效評估。根據分析結果，提出改善方向供客運業者參考。 Accompanying with rapid economic development and the increase of vehicles in private sector, traffic congestion prevails in road network and energy consumption and carbon dioxide emissions become more serious in the transport sector in an urban area. The transport company faces the increasing pressure of the requirement to reduce carbon dioxides, piers competition and internal problems. Long-term final deficit may force the transport company to deteriorate its service quality to passengers. Given the undesirable input/output of the transport industry, the study uses the performance assessment framework, suggested by Fielding et al. (1985), to shape the dimensions of cost effectiveness and service efficiency to investigate the trend of change and catch the direction of improvement.. With the Malmquist index, the study employs the “Three-Stage SBM-DEA” method by Avkiran & Rowands (2008) to exclude both external factor and statistical interference to evaluate and choose the route with the better performance for the empirical case of Taichung city. According to the analysis, the result may provide the government and managers of transport company to improve passenger service in the near future.
