试图从一个新的理论视角说明交通运输与经济增长的关系，对交通运输与经济增长关系问题的研究，可以看成是经济学关于分工问题研究的一个组成部分，是一个最基本的经济学问题。目前经济学对于产业间分工与市场规模之间的相互作用关系，制度安排促进交通业发展的内在机制，及由此导致的收益递增式经济增长还缺乏深入研究，经济学中还缺乏一个分析经济增长、交通运输基础设施、制度安排之间相互作用机制的理论框架。本文试图以美国19世纪经济发展中，制度安排推动了交通运输业的发展，交通运输业的发展促进经济增长，而经济增长有促进了交通运输业发展的历史事实，对上述问题进行初步的理论探讨。

On the Relationship Between the Transportation Industry and Economic Growth
