清中叶是闽台贸易发展由盛转衰的关键时期。这时期闽台贸易总量可通过考证闽台之间运输海船的数量与载重量而得到统计。清中叶闽台贸易总量的定量分析也为深入研究闽台贸易史和闽台经济史提供了坚实基础。 The middle and mid-Qing period is a crucial period for the development of commerce between Fujian and Taiwan from prosperity to decline. The total volume of trade between Fujian and Taiwan during this period can be estimated by examining the number and carrying capacity of sea-going ships between Fujian and Taiwan. The quantitative analysis of the total trade volume between Fujian and Taiwan in the mid-Qing Dynasty also provides a solid foundation for further studying the history of trade between Fujian and Taiwan and the economic history of Fujian and Taiwan.
