本研究藉由資料包絡分析與麥氏生產力指數 (Malmquist Productivity Index, MPI) 來衡量美國市場車商主力車款的營運銷售績效表現。除此之外，本研究更進一步運用拔靴法(Bootstrap)對麥氏生產力指數進行敏感度分析，藉以驗證生產力指數之穩定度。本研究以2003至2012年，共計79台車為研究樣本。研究結果顯示，就整體而言，各車款在績效表現上具有一定水準，需改善幅度不大。Pickup車款平均效率值優於SUV、Minivans與Sedan/Hatchbacks。二萬美金以下的車款效率值相對較低。就技術上沒有太大的進步，反而呈現退步。最後，透過拔靴法，可使研究結果更為嚴謹，並具有可信度，進而可合理的進行統計估計與推論。;This research using Malmquist Productivity Index (MPI) to measure operating sales performance of the mainstream market’s car in the US. In addition, this study further use of bootstrapping (Bootstrap) productivity index for the McPherson sensitivity analysis in order to verify the stability of the productivity index. This research using 79 cars sells in the US from 2003 to 2012 for the study sample. The results show that all cars have a certain level of performance on performance, just need improve marginally. Pickup vehicles have average efficiency value than SUV, Minivans and Sedan / Hatchbacks. Under $20000 US dollars has relatively low efficient cars value. Technically there is not much progress, but showed deterioration. Finally, through the bootstrap method, the results can be more rigorous and credible, and thus can be estimated with reasonable statistical inference.
