开放通商之后,为了适应对外贸易大型船舶的停泊需要,上海、天津和汉口三大口岸的城市重心逐渐由浅水沿岸向深水沿岸转移、由“华界”向租界转移、由旧港城向新港市转移,从而完成了从内向型小港城向外向型国际化大港市演变的历史进程。 After the opening up of trade, in order to meet the needs of mooring large vessels for foreign trade, the city centers of gravity of the three major ports of Shanghai, Tianjin and Hankou gradually shifted from the shallow coast to the deep-water coast and shifted from the “Ward Bound” to the Concession from Old Port City to New Port City transfer, thus completing from the inward-oriented small port city to the internationalized Dagangxu evolution of the historical process.
