The paper aims to have a more profound understanding of the development process of intelligent logistics and lay a theoretical foundation for intelligent transformation and upgrading of logistics enterprises. Based on the essential connotation of intelligent logistics, the paper identified the four main elements that play a decisive role in the development of intelligent logistics: logistics enterprises, government, demand subject and technical service intermediaries. A four-dimensional model of intelligent logistics composed of the four main elements was constructed. It analyzed the relationship between the four main elements of intelligent logistics and the evolution process of intelligent logistics development. Combining the S-curve of intelligent logistics development and the main driving elements in different periods, the development process of intelligent logistics is divided into government-driven development stage, demand subject pulled-enterprise pushed development stage and consciously balanced development stage, and the concrete manifestations of the four-dimensional model in different development stages were expounded.
