本文分析了运输契约由自雇运输向受雇运输发展的运输契约深化过程,认为网络经济是推动不同运输契约结构形成的主要原因。网络经济使大量交通运输活动在交通区位、线位和站位上集聚,对运输资源和和运输生产全过程控制力增强,从而使交易风险和不确定性得到控制,专业化分工水平得到深化。 This paper analyzes the process of deepening the contract of carriage of transportation contract from self-employed transport to employed transport, and considers that the network economy is the main reason to promote the formation of different transport contractual structures. The network economy brings a large number of transportation activities together at traffic locations, lines and stations, and increases control over the entire process of transportation resources and transportation and production so as to control the risks and uncertainties of transactions and to deepen the level of specialized division of labor.
