The length of time required for the 14 major development projects varies according to their nature. For example, China Steel's third expansion project can be completed this year, yet only about five kilometers a year can be completed of the Taipei municipal rapid transit system, which will reach 100 kilometers in length, while the urban waste disposal project is an ongoing one.
十四項重要建設計畫，依其性質不同，所需時間長短也不同；例如中鋼第三期擴建計畫今年就可完成，台北地區大眾捷運系統長達一百公里，平均每年所能完成的不過五公里左右，都市垃圾處理計畫，會一直作下去。
