China's coastline from the south to the north is covered with all kinds of ports, each port is an economic entity, which not only undertakes the domestic and international commercial trade, but also leads the economic development of the port location. The port economy has become an indispensable part of the modern Chinese economy. As an important driver of regional economic development, port economy is an important driving force to adjust the regional industrial structure. Its development not only benefits from the inherent favorable conditions of the port and external promotion factors, but also has a close relationship with the port collection and distribution system. The collection and distribution system is the basis for the survival and development of ports, and is one of the important pillars of port development. In recent years, port throughput has been showing a rapid growth trend. The rapid growth of port throughput not only puts forward higher requirements for the construction of port infrastructure, but also brings greater challenges to the further improvement of port collection and distribution system. At present, the evaluation of port collection and distribution system lacks a relatively unified standard. In this regard, this paper selects Tianjin, Qingdao, Ningbo and Guangzhou as the research object, uses the multi-attribute decision-making model, uses the relevant evaluation index to carry on the comprehensive evaluation comparison, and puts forward the corresponding policy suggestions according to the related insufficiency.
