明清的福建海商在海禁政策面前选择了向北部沿海拓展的路径。江浙沪是当时手工业较为发达的地区,棉纺织、丝织业等均较发达,福建则是亚热带水果大量出产的地区,福建需要江浙沪的产品,江浙沪也需要福建和福建商人采购来的产品,双方通过海上商业交流达到了各自的目的。这表明海上商业交流已成为清代地区间物资调剂余缺的重要途径。 Fujian’s maritime merchants in the Ming and Qing Dynasties chose to expand their route to the northern coast in the face of the ban on sea transportation. Jiangsu, Zhejiang and Shanghai were more developed handicraft areas, cotton textile, silk industry are more developed, Fujian is the production of large quantities of subtropical fruits, Fujian need Jiangsu, Zhejiang and Shanghai products, Jiangsu and Zhejiang also need to Fujian and Fujian merchants to purchase products Both sides reached their own goals through commercial exchanges at sea. This shows that the commercial exchange at sea has become an important way for the shortage of materials in the Qing Dynasty.
