We argue that this is due to the benefit of the economies of agglomeration and the externalities from the lower transportation cost. 此外，車(chē)站地之地價(jià)上升幅度也大于非車(chē)站地，這反映運輸量上升所產(chǎn)生的聚集經(jīng)濟與外部利益。
The result is that the cities both have not seen agglomeration economy effects, but the special industrial sectors and zones have there own agglomeration economy advantages. 但從具體行業(yè)和特定地區來(lái)看，上海市和天津市呈現了各自的聚集經(jīng)濟優(yōu)勢。
