On the Economic Development of North-eastern Fujian and Sandu' Ao Self-established Trading Port in Modern Times——on the Basis of the Ten-year Customs Report in Sandu'Ao Port(1899-1931)

Sandu'Ao,as a self-established trading port,is not developed as a typical trading port in modern times,which has a direct relationship with the long time unchanged economic type in its hinterland——north-eastern Fujian.From the start,Sandu'Ao port only worked as a transfer station instead of a junction center station for economy in north-eastern Fujian linking to the outside world,therefore its function was to simply organize and carry away goods in linterland rather than to spur on economic development and economic type transformation in hinerland by port economy.
