本研究採資料包絡分析法(Data Envelopment Analysis，DEA)視窗模式(Window Analysis)模式探討海峽兩岸六個直轄城市2001年至2005年城市競爭力及生產力變動趨勢，以敏感度分析探討各項投入變數對城市整體競爭力之影響。
研究結果顯示：整體平均效率不佳，僅達0.280，顯示海峽兩岸直轄市中，除台北市以外均有明顯競爭力不足的窘境。六座城市中以台北市競爭效率值達0.983，表現最佳；中國境內四座城市效率值則有很大的成長空間，但均呈現穩定成長中，應改善勞動人口素質方面著手，長期應從教育政策方面改善，並以第三產業為重點目標，以提升勞動人口的生產效能；短期間應以職業訓練為主，培育第二產業及第三產業基礎人力；台北市已達發展飽和，應吸引外資或其他資金創造生產機會。

This study employed DEA Window Analysis Model to assess the performances on competitiveness of 4 municipalities in China and 2 municipalities in Taiwan over 2001-2005. Sensitivity Analysis was applied to identify the individual input variable influences on these municipalities performances.

Our finding indicated that：the overall performances poorly performed with an average efficiency score of 0.280. The well-performed municipality is Taipei City in Taiwan with an efficiency score of 0.983. 4 municipalities in China will have a long way to go and should promote employees in the field of service abilities. In the short term, China may provide employees with vocation trainings and educate employees with work skills in productive industry and services fields. In the long term, China should improve education policy and focus on upgrading employees in the field of service skills. In the future, Taipei should try to expand foreign capitals and find new ways to create more opportunities to maintain her competitive advantages.
