虽然运输和集聚经济之间的相互作用被广泛接受，但没有足够的研究试图直接的实证量化。使用美国大都市地区的平衡面板数据集，我们估计了一个联立方程系统，以衡量通过运输提供而产生的城市群经济的间接影响。我们的研究结果表明，公共交通加强了城市群的影响，而道路里程似乎削弱了它。研究结果强调了公共交通在支持正向城市群外部性方面的重要性。
While the interaction between transport and agglomeration economies is widely accepted, there is insufficient research attempting at a direct empirical quantification. Using a balanced panel dataset for US metropolitan areas, we estimate a system of simultaneous equations to measure the indirect effect of urban agglomeration economies which arises through transport provision. Our findings suggest that public transit reinforces the effect of urban agglomeration, whereas road lane miles appearto weaken it. The results highlight the importance of public transit in supporting positive urban agglomeration externalities.
