This is especially true for notebook computers. If Taiwan and mainland China establish direct links, shipping costs from Shanghai to Taipei would be less expensive than shipping costs from Kaohsiung to Taipei. A computer could make several trips across the strait before final assembly. For example, a notebook's LCD screen, which accounts for a large portion of the computer's cost, can be produced in Taiwan and attached during final assembly.
尤其筆記型電腦中有三百多種零組件，如果兩岸可以三通，從上海到台北的運費比從高雄到台北還便宜，一台電腦在完成前，可以在兩岸間來來回回好幾趟，例如佔成本很大一部份的液晶顯示器，就可以在台灣生產好，最後再組裝上去。
